Three years from today (Oct. 14, 2023), an annular solar eclipse crosses the USA. I've written a book full of maps and information about this event. tinyurl.com/yyxgnsco

Comet #NEOWISE continues to perform well. It's easy to see with the naked eye 75 minutes after sunset, low in the northwest. this shot from Portal, AZ on 7/17.

@FEspenak Great comet, great photo. But don't forget C/2006 P1 (McNaught) - now THAT was spectacular.

Comet NEOWISE is the best comet in decades. See it low in the NE about 75 minutes before sunrise. This photo July 7, Portal, AZ.
