On Saint Patrick's Day, while searching for Earth approaching asteroids with the Catalina Sky Survey's 60 inch telescope on Mt. Lemmon, Arizona I spotted a slightly enlarged star like object with a…
Recently a pair of JPL SynTrack Robotic automated telescopes located at a high altitude low light pollution site in California provided 4 tracking data points taken less than 30 minutes apart which…
To give you an idea of the asteroid traffic in our neighborhood, on a mostly cloudy night, through holes in the clouds, in a space of less than 2 hours, my Catalina Sky Survey teammate Richard…
