Arrange 9 photos together in PowerPoint.

During the total lunar eclipse on November 8, when the moon passed through Earth's umbra just before its third contact, I photographed the dark red moon's edge starting to appear blue. From the third contact to the fourth contact, it can be seen that there is a very obvious blue band between the red dark area and the bright area of the moon! This set of photos shows how the blue band changes throughout the process. According to some sources, blue band appearing on the surface of Moon is due to refraction of sun light by our Ozone Layer.
