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 team, the Catalina Sky Survey, would not find a single asteroid without Steward Observatory's Mountain Lemmon Operations, or Mtn Ops for short.

- The closest passage by a non-impacting space rock was made by the tiny asteroid 2011 CQ1.  It was discovered by my Catalina Sky Survey teammate Richard Kowalski, on February 4, 2011.
