Main astronomical events of May 2023

The central event of May this year is the lunar eclipse, the final part of which can be observed from the territory of Ukraine. During it, the Moon will not “touch” the earth’s shadow, but it will sink 96% of its diameter into the penumbra. Such a large penumbral phase allows us to expect that the appearance of our natural moon will change significantly, and it will even be possible to notice it with the naked eye: the northern (upper) edge of the lunar disk will look darker than the southern one. In Kyiv, on the evening of May 5, the Moon will appear above the horizon in almost the maximum phase of the eclipse. In the east and south of Ukraine, the conditions for observing this phenomenon will be slightly better.

The course of the penumbral lunar eclipse on May 5, 2023. In Kyiv, the moon will rise during the maximum phase (in the center). The beginning of the eclipse (on the right) will not be observed from the territory of Ukraine

The next morning, the maximum of the meteor shower n-Aquarid associated with the famous Halley comet (1P/Halley) is expected. But in our latitudes it is quite inconvenient to observe it, besides, this year the visibility of meteors will further complicate the Moon.
