sky phenomenon in 2018
halo steemians, many events in the sky that we will see in this year. hopefully, we can still see the phenomenon. lets you have to set up telescopes and other necessary tools. Good luck!!!

prepare yourself to observe the celestial events of 2018. This year Indonesia is lucky enough to witness the Total Moon Eclipse that occurred in January and July. For the solar eclipse, it seems we have not been lucky.
Do not worry. There is still an annual meteor shower that will grace the night sky as the Earth crosses the remaining areas of comet dust and planetary opposition events and planetary opposition events.
Eclipse
The 2018 eclipse season will begin with the Total Moon Eclipse that occurred at the end of January and followed by a solar eclipse some two weeks later. In 2018, the eclipse season will be filled by 5 eclipses with the composition of 3 solar eclipses and 2 lunar eclipses.
January 31 - Total Moon Eclipse
GBT January 31 will be the first eclipse in the 2018 eclipse series. The January 31st GBT event is generally observable from all over Indonesia since the rising Moon. Especially for parts of western Indonesia, the moon rises after the first contact when the Moon has begun to enter the earth penumbra cones. At the moment there are not many visible changes because it only happens to dim.
When the total Moon eclipse, the Moon will enter the shadow of the Earth and looks reddish to the observer on Earth. For January 31st GBT, the Moon will begin entering Earth's shadow at 18:48 WIB and spend 3 hours 22 minutes in Earth's umbra. Overall lunar eclipse will occur for 5 hours 17 minutes with a total eclipse duration of 1 hour 16 minutes 4 seconds.
GBT events January 31, 2018, can be observed from Asia including Indonesia, parts of Europe, Russia, Australia, the Pacific region, as well as the western and northern American regions.
February 16 - Partial Solar Eclipse

Throughout 2018, parts of the Earth could observe the closure of some of the faces of the Sun. During GMS, the location across the eclipse will only experience dimming or decreasing sunlight.
For GMS February 15, only observers in the South American region are fortunate enough to witness the eclipse. And even then only a small part of the Sun covered the Moon. Some countries that can see the partial eclipses are parts of Chile, Argentina, Uruguay, a southern part of Paraguay and the southern part of Brazil. Observers in the southernmost parts of South America, including the island of Malvinas, can observe a loss of 30% of the sun's light. Other areas traversed are the Atlantic Ocean, the Pacific Ocean and parts of Antarctica.
Want to make observations? Go to the existing research base in Antarctica.
July 13 - Partial Solar Eclipse
The third eclipse of 2018 is again a partial solar eclipse (GMS). The second solar eclipse in this eclipse season will cross only a small part of the uninhabited area of southern Australia or precisely in the Viktoria region, and a small part of South Australia. In addition, the island of Tasmania and a small part of southern New Zealand will also experience dimming that may not be the difference because the sun's light is only reduced by <5%. The Indian or Indian oceans and the Pacific Ocean are the areas to be passed by GMS.
The peak of the eclipse and the lion's share of GMS July 13 will again occur in the uninhabited areas of Antarctica.
July 28 - Total Moon Eclipse
The second and final lunar eclipse in 2018 occurs July 28 when the Moon enters the shadows of the Earth and appears reddish to observers on Earth.
Total Moon Eclipse.source
Just like the January 31st GBT incident, the whole of Indonesia can still observe a total lunar eclipse that begins midnight until dawn. As a result, for some parts of Indonesia, not the whole process of the eclipse can be witnessed. The moon goes down while still in eclipse condition.
Some parts of Papua will not even be able to observe the peak of a total lunar eclipse because the Moon is set and the Sun rises. The area of western Indonesia is still fortunate enough because of the dawn of the moon when the Moon was out of the shadows of the Earth.
When the total Moon eclipse, the Moon will enter the shadow of the Earth and looks reddish to the observer on Earth. For the July 28th GBT, the Moon will begin entering Earth's shadow at 00:14 pm and spend 3 hours 54 minutes in Earth's umbra. Overall lunar eclipse will occur for 6 hours 13 minutes with a total eclipse duration of 1 hour 42 minutes. Uniquely this is the longest lunar eclipse since 18 years ago.
The events of GBT July 28, 2018, can be observed from South America, Europe, Asia, Australia, Africa, the Atlantic Ocean, Indian Ocean, and Antarctica,
August 11 - Partial Solar Eclipse
The 2018 eclipse season closes with the partial solar eclipse (GMS). This third solar eclipse will be visible to the northern hemisphere community. If two previous GMS crossed the south polar region, this time the north polar region visited. The countries that can see the GMS are the northeastern regions of Europe, northwest Asia, northern Canada, Greenland, the Atlantic Ocean and the Arctic Ocean. The peak of the eclipse occurred in Russia in the East Siberian Sea.
Opposition & Conjunction
March 4 - The Neptune Conjunction
Neptune is at its greatest distance from Earth and is on the opposite side of Earth and the Sun will be between Neptune and Earth. From an observer's point of view on Earth, Saturn will look very close to the Sun and will not be visible to Earth-observers.
May 9 - Jupiter opposition
The largest planet in the Solar System will be in the closest position to the Earth and look very bright in the night sky. Observers can enjoy the presence of Jupiter in the Libra constellation with a magnitude of -2.5 magnitudes since the Sun sets until dawn. Observers can also observe the Galilean satellites that circle the giant planet.
April 18 - Conjunction Uranus
Uranus will be in the furthest position from Earth and the Sun is between the two planets. As a result, observers on Earth will not be able to see the rotating ring planet, because the distance is very close to the Sun.
27 June - Saturn Opposition
The beautifully ringed planet will be in its closest position to Earth on 27 June. So do not miss out! Saturn will look brighter than other times and will be able to enjoy its presence all night in the constellation Sagittarius. Use your telescope and camera to take pictures of this ring planet.
27 July - Mars Opposition
Mars will be at its closest position to the Earth and appear as a bright red dot in the night sky. At the opposition, Mars is at a distance of 0.39 AU or about 58.5 million km with a magnitude of -2.8 magnitudes.
Do not worry, Mars will not look as big as the Moon. No twin moons. This red planet will be easy to find in the constellation of Capricorn as a bright red dot below the full moon.
September 8 - Neptune opposition
It is not easy to observe this blue ice planet. September 8 marks the closest position to Earth. When the Neptune opposition was at a distance of 28.93 AU in the constellation Aquarius with a magnitude of 7.3 magnitudes. To get a glimpse of this ice planet, prepare a telescope and do not be disappointed to find Neptune just a blue dot on your telescope.
24 October - Uranus Opposition
After Mars, Jupiter, Saturn, and Neptune are at their closest position from Earth, it is now Uranus, the other giant ice planet to be close to Earth. The rolling planet will look unique as a greenish-green dot on the telescope. To find it, point the telescope to the constellation Aries. When the opposition Uranus was in the constellation Aries with a magnitude 5.7 magnitude.
November 26 - Jupiter Conjunction
Jupiter is at the greatest distance from Earth. When conjunction with the Sun, Jupiter will be on the opposite side of Earth with the Sun between them. To the observer, Jupiter will disappear from the night sky.
Equinox & Solstice
March 20 – Equinox
The sun is in the equinox or above the equator. The duration of day and night becomes the same ie 12 hours. For people in the northern hemisphere, the 20th of March is the Vernal Equinox or the spring turning point that marks the beginning of spring. In the southern hemisphere, the equinox in March is an autumnal equinox that marks the beginning of autumn.
Vernal Equinox will occur on March 20 at 23:15 pm.
June 21 - Solstice (Summer Solstice - Northern Hemisphere; Winter Solstice - Southern Hemisphere)
The summer turning point for the people of the Northern Hemisphere and the winter turning point for the inhabitants of the Southern Hemisphere. In addition, for people in the southern hemisphere, this is the longest night and for those in the north, this is the longest day.
The summer turning point will occur on June 21st at 17:07 pm.
September 23 – Equinox
The sun is in the equinox or above the equator. The duration of day and night becomes the same ie 12 hours. For people in the northern hemisphere, September 23 is an Autumnal Equinox or autumn turning point that marks the beginning of autumn. In the southern hemisphere, on the other hand, the equinox in September is a vernal equinox or spring equinox that marks the beginning of spring.
Autumnal Equinox will occur on 23 September at 08:54 pm.
December 21 - Solstice (Winter Solstice - Northern Hemisphere; Summer Solstice - Southern Hemisphere)
The winter turning point for the people of the Northern Hemisphere and the summer turning point for the inhabitants of the Southern Hemisphere. In addition, for people in the southern hemisphere, this is the longest day and for those in the north, this is the longest night.
The winter turning point will be December 22 at 05:22 WIB
Meteor Rain
January 4 - Quadrantid Meteor Rain
Quadrantids, the First Meteor Shower .source
The year 2018 will be preceded by Quadrantid meteor showers in the sky from 28 December to 12 January. The Quadrantid meteor shower peak will take place on 4 January 2018 at 04:00 AM in the morning. Quadrantid meteor showers appear from the Bootes which appeared at 03:00 am in the northeast. In contrast to other meteor showers, the peak of the Quadrantid meteor shower lasted only a few hours.
At night peak observers can enjoy at least 50-120 meteors per hour. However, for observers in the Southern Hemisphere, Quadrantid meteor shower is not as good as observers in the North and the number of meteors that can be enjoyed is also less. Especially for the year 2018, the Moon will be the main source of light pollution because it just passed the phase of full-moon or convex ~ 99%.
April 23 - Lyrid Meteor Rain
Meteor showers coming from Thatcher C / 1861 G1 comet tail dust will peak on April 23 in the early hours of precisely at 01:00 am. Lyrid meteor shower can be enjoyed by Lyra constellation that the direction comes, rising at 23:00 pm. Early early moons had already set in the middle of the night so that observers could enjoy the presence of meteor trails in the sky until dawn. At the peak, observers can only see 18 meteors per hour moving at speeds of 48.8 km/sec.
May 6 - Eta Aquariid Rain Meteor
From April 19 to May 28, Eta Aquariid meteor rains from the rest of Halley's comet will peak on May 6th. The meteor shower will appear to come from the Aquarius constellation and can be observed after midnight until dawn after the constellation Aquarius rises midnight.
The new moon will reach the final and final stage of the farming at midnight at 22:04 pm, followed by Aquarius Race an hour later. At peak night, observers can see 40 - 85 meteors every hour with a speed of 66.9 km/sec.
July 30 - South Delta meteor showers
The meteor shower of the Aquariid Delta is a meteor shower from Marsden and Kracht Sungrazing comets. Just like the Aquariid eta, southern delta meteors of Aquariid delta also appear to originate from the constellation of Aquarius and will peak on July 30 with 16-25 meteors per hour. But if you want to make observations, the rain of meteors Aquariid can be observed from sunset until dawn. Likewise, the Moon which rises at 19:50 WIB will be perched in the sky until dawn and become a source of light pollution for the observers.
July 30 - Alpha Capricornid
Mag. -13 alpha-Capricornid recorded on 29 July 2016.source
In addition to the southern Aquariid delta, on 30 July the alpha Capricornid meteor shower will reach its peak. Meteor showers that run from 3 July to 15 August will appear to come from the direction of the constellation Capricorn and derived from the comet 45P Honda-Mrkos-Pajdusakova. Another alleged origin of this meteor rain from the 2002 EX12 asteroid later known as the comet 169P / NEAT.
The peak of the Capricornid meteor shower will occur on July 30 at a rate of 5 meteors per hour. However, there is usually a fireball that forms and passes through the night sky. The Capricorn constellation has been published since the Sunsets and observers can enjoy the alpha Capricornid meteor shower all night until dawn. Again a large convex Moon would be the main source of light pollution for this one meteor shower.
August 13 - Perseid Meteor Rain
Perseid Meteor Rain 2009.source
Starting July 17 - August 24, Perseid meteor shower from Swift-Tuttle's comet dust will peak on August 13th. At night the peak is estimated 100 meteors will pass every hour and seem to come from the constellation Perseus. For light-pollution-free observation sites, observers can watch at least 50-75 meteors per hour.
Perseus new constellation will be published after midnight ie at 01:00 pm. The moon has just passed the new Moon phase and has been set since 19:48 pm. The dark sky is the perfect condition for hunting for meteors from midnight until dawn. Perseid constellation rises in the northeast.
October 21 - Orionid Meteor Rain
Orionid Meteor Shower 2017.source
Orionid meteor showers derived from Halley comet dust residue will again adorn the night sky from 2 October to 7 November. As the name implies, the Orionid meteor shower appears to emerge from the constellation of Orion the Hunter and reaches its peak on 21 October.
At peak night, observers can enjoy 25 meteors per hour that speed at 66 km/sec. The Orion constellations appear at 22:16 pm and the large convex Moon that is heading west and sets at 2:58 pm will be light pollution that interferes with observations.
November 5 - South Taurid Meteor Showers
South Taurid Meteor Showers 2015.source
The Taurid meteor shower comes from the Asteroid 2004 TG10 dust grains and the remaining 2P of Encke Comet dust, lasting from September 10 to November 20 and never producing more than 5 meteors per hour. Interestingly, this Taurid meteor shower is rich with fireballs.
The peak of meteor showers that came from the Taurus constellation took place on November 5, with only 5 meteors per hour whose speed was only 28 km/sec. Taurid meter rains can be observed after the sun sets as the Taurus constellation also rises in the east until dawn as this constellation will set in the west. Moonlight will not be a factor of light pollution because ahead of the new Moon and the moon rising in the morning at 03:28 pm.
November 12 - North Taurid Meteor Rain
The North Taurid meteor shower also appears to come from the Taurus constellation and starts from October 20 to December 10 with a peak on 12 November. At night peak, North Taurid Meteor Rain will adorn the sky with 5 meteors per hour at a rate of 29 km / h. The constellation of Taurus rises after the sun sets and can be observed until dawn. The thin crescent will not have any effect on the pollution of natural light and the new Moon passing through the new Moon phase is set at 21:52 WIB. The combination of North and South Taurid meteor storms that are still taking place in late October and early November are interesting attractions in the sky. Especially with the presence of fireball.
November 17 - Leonid Meteor Rain
On the morning of November 17, 1966, skywatchers in western North America were spellbound by an awesome flood of Leonid meteors peaking around 5 a.m. Mountain Standard Time..source
The Leonid meteor shower had once triumphed with Leonid storm, but now meteor watchers can only watch 15 meteors per hour at peak on November 17th. The Leonid meteor shower from Tempel-Tuttle's comet remains lasts from November 6 to 30 and appears to have come from the Leo constellation.
For meteor hunters, the new Leo constellation will rise midnight at 00:21 pm and about 30 minutes later, the convex Moon that adorns the night sky will set. Precisely at 00:50 pm. The sky without the moon from midnight to the early morning will be ideal conditions for hunting meteors that pass with speed of 77 km/sec.
December 14 - Geminid Meteor Rain
At the end of 2018, Geminid meteor shower back into an exciting spectacle with 120 meteors per hour at peak. The meteor showers coming from the Gemini twin will last from December 4-17 and the peak will be December 14th. Geminid meteor showers traveling at a speed of 35 km / s, can be enjoyed after the constellation Gemini rises between at 20.00 pm. The moon is on its way to the early and early twilight stage at 23:27 WIB. The best time for observation can be done after 22:00 pm when the Gemini constellation is high enough and from midnight till dawn, there is no Moon that is a natural light pollution factor. Thanks!!!

Already booked them all on my schedule! It was really nice to read them all over again, can't wait!!
:)
Interesting all your compilation
thanks
Thank you for this. I am looking forward to some warm and clear nights to dedicate some time to looking up at the night sky.
