At the time of the peak of the Lyrid meteor shower, it was estimated that it was only 18 meteor per hour moving at a speed of nearly 50 kilometers per second. From the community website, the best time for observation starts at 02.00 WIB when the moon sets.
Meanwhile, the Pi Puppid meteor shower took place from April 15 – 28, 2021. With a speed of around 18 kilometers per second, the peak period was on April 23 with around 18–40 meteors per hour. Meteor showers from the remains of comet 26P / Grigg-Skjellerup can be observed from sunset to midnight as the constellation Puppis sinks.
As for several other celestial phenomena in April, namely Mercury and Venus, it will be difficult to find earth observers. The two planets in that time of rising and setting almost coincide with the sun so that their appearance seems to disappear behind the bright sunlight.
In addition to the meteor shower, there was an occultation of Mars by the moon on April 17, 2021. At that time the planet Mars seemed to be hiding behind the moon. Then it will appear from the side of the luminous moon. This phenomenon can be witnessed in the western part of Indonesia. Starting from Aceh at 20.08 WIB onwards until Bali and parts of Kalimantan. As for the central and eastern regions of Indonesia, the moon and Mars had already set before the occultation process began.
