The end of March and almost the whole of April will continue a favorable period of evening visibility of Mercury. The maximum eastern elongation of the planet will take place on April 11, when it will move away from the Sun by almost 20 °. The time interval between the end of civil twilight and its setting over the horizon for 50° north latitude for about three weeks will exceed an hour. However, the conjunction of the Moon, Mercury and Uranus on April 21-22 is already quite difficult to see, since it will happen at 14-15° from our luminary.
A rare annular total solar eclipse on April 20 is not observed on the territory of Ukraine even as a partial one — it will be seen by residents of Australia, Indonesia, Southeast Asia and some islands of the western Pacific Ocean. For the next few days, the Moon will have a small phase, without interfering with observations of the Lyrid meteor shower, the maximum of which falls on April 22. At this time, under the condition of a clear dark sky, up to 20 meteors per hour can be noticed, although in some years the flow power is even higher.
