Podcaster: Dr. Al Grauer
Title: Travelers in the Night Eps. 719 & 720: What A Night & Large PHA
Organization: Travelers in The Night
Description: Today’s two stroy:
- To give you an idea of the celestial traffic in our neighborhood, on a recent clear night, using our 60 inch telescope on Mt. Lemmon, Arizona, my Catalina Sky Survey teammate Hannes Groller posted 20 new objects on the Minor Planet Center’s Near Earth Object Confirmation Page. In the future five of these asteroids may become a valuable source of raw materials for Martian colonists.
- Recently my Catalina Sky Survey teammate Richard Kowalski was asteroid hunting in the constellation of Pegasus with our Schmidt telescope on Mt. Bigelow, Arizona when he discovered a 2,000 foot diameter space rock streaking through the night sky. The extremely remote possibility that a big one might have our number on it keeps asteroid hunters going to their telescopes.
Bio: Dr. Al Grauer is currently an observing member of the Catalina Sky Survey Team at the University of Arizona. This group has discovered nearly half of the Earth approaching objects known to exist. He received a PhD in Physics in 1971 and has been an observational Astronomer for 43 years. He retired as a University Professor after 39 years of interacting with students. He has conducted research projects using telescopes in Arizona, Chile, Australia, Hawaii, Louisiana, and Georgia with funding from NSF and NASA.
He is noted as Co-discoverer of comet P/2010 TO20 Linear-Grauer, Discoverer of comet C/2009 U5 Grauer and has asteroid 18871 Grauer named for him.
