Corona vs. Halo

The video tutorial explains how observing the moon can reveal different atmospheric phenomena such as lunar halos and coronas. A lunar halo, seen around the bright moon, indicates the presence of high cirrus clouds made of ice crystals. In contrast, a corona, which appears as a bright fuzzy area, suggests middle-level altocumulus clouds composed of water droplets. Historically, these observations have been used for weather forecasting. While theoretically possible, seeing both a corona and a lunar halo simultaneously is rare due to the specific cloud conditions required.
