"Your Guide to Watching Lunar and Solar Eclipses"

A penumbral lunar eclipse is set to occur on Sunday night or Monday morning, depending on the time zone, as a prelude to April's solar eclipse. This subtle event, caused by the Earth casting a shadow on the moon, will result in a slight dimming of the moon's full face. While the change may be difficult to observe with the naked eye, using binoculars or a telescope is recommended to witness the moon's brightness change throughout the night.
