In April, we are expecting as many as two new moons, and the last of them, falling on April 30, will be accompanied by a partial solar eclipse, not visible from the territory of Ukraine. At the end of the month, comet PanSTARRS (C/2021 O3) will appear in the evening sky — it can be seen with small amateur telescopes, and possibly with the naked eye. But noticeably better conditions for its visibility will come in May. Also in the second half of April, Mercury, the planet closest to the Sun, will be clearly visible above the western horizon in the evenings.
