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.

Today's 2 topics:

- Minghu Tan, a PhD student at the University of Glasgow has been investigating the possibility of deflecting a small asteroid causing it to graze the Earth's atmosphere and thus use aerobraking to put the small space rock into Earth orbit.

- The fireball meteor streaking across the sky the early evening of January 17, 2018, witnessed by 700 observers in 11 States and Canada was also recorded by infrasonic microphones and seismometers.
