Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org Today's 2 topics: - My Catalina Sky Survey teammate Josh Hogan was asteroid hunting in the constellation Sextans with our 60 inch telescope on Mt. Lemmon, Arizona when he discovered the largest asteroid in nearly a decade. 2023 HQ2 is its name. - The natural night sky is alive with its own lights. In addition to celestial sources often there is natural night sky airglow powered by space weather from above and/or tropospheric activity from below. It is not the Aurora Borealis. Amazing images show green airglow waves which are brighter than the Milky Way.The theory behind these beautiful images remains a mystery.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
