Travelers in the Night Eps. 763 & 764: Hogan’s Big Rock & Green Airglow

The 365 Days of Astronomy

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.
