It is only necessary to count the days to reach the end of 2017. For 356 days, there have been many interesting astronomical events.
On December 14, 2017, we have witnessed geminids meteor showers at 9 pm to 4 am the following morning. In addition, on December 3, 2017 the first full supermoon and the last time in 2017 occurred.
Interesting sky phenomenon can still be witnessed in 2018. EndJanuary 2018 for example, will occur super rare phenomenon.
The moon that rises on the night of January 31, 2018 is full moon, blue moon, super moon aka supermoon, once every two months will experience eclipse. Four phenomena at once are rare.
Full moon occurs every 29.5 days. At the distance closest to the earth (perigee point), the moon looks bigger. That is the cause of the emergence of supermoon phenomena.
Because the cycle is every 29.5 days, in one calendar month BC can occur twice full moon. In January 2018, the first full moon fell on January 1, 2018 and the second on January 31, 2018.
The second full moon within the same month is popularly called the blue moon. However, the color of the moon certainly does not become blue.
During the second full moon, the earth's position lies between the sun and the moon. In the end, the moon blocks the moon from the sun, causing an eclipse. At eclipse, the moon is red like blood.
Based on the analysis of the US Aeronautics and Space Agency (NASA), eclipse phenomenon as well as three others that can be witnessed from Indonesia.
The beginning of the eclipse occurred at 17:51 pm. The western part of Indonesia will skip this early stage. However, at the peak of the eclipse at around 20:55 pm.
Because rare, not to miss the four phenomena of the month at once. Hopefully that night is also sunny weather for all countries.
