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: - Fireballs are meteors which become brighter than the planet Venus and can sometimes be seen in the daytime. If you are lucky to see a fireball send in your report to the American Meteor Society and become a citizen scientist. - Greg's comet, C/2017 W2 (Leonard), comes into our neighborhood once per human lifetime and spends most of it's time in the lonely space high above or far below the rest of the members of our solar system.   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!
