Description: Today’s two stroy:

  • Fuzzy, spread out, asteroid images due to atmospheric and or equipment produced distortions can cause important objects to slip through an asteroid hunter’s discovery images undetected. A careful monitoring of the temperature at a number of different locations in the observatory environment and using fans and other techniques to minimize temperature differences restores the power of a telescope so that it can detect possible asteroid threats to planet Earth.
  • From the time 3 million years ago that our ancestor Lucy walked in what is now Ethiopia until the widespread use of electric lighting began in the 1880s the changing panorama and awe inspiring beauty of the natural night sky was available to most human beings.

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.
