AAVSO Volunteer Effort Maps The Stars

Astronomers Map 40 Million Stars

"Astronomers will soon have access to a new map of the sky that accurately measures the brightness and position of over 40 million stars. This map is a result of the AAVSO Photometric All-Sky Survey, which has completely covered the sky at a level 100 times fainter than any prior stellar catalog. Millions of stars will have their brightness and color measured accurately for the first time in this survey. The survey is predominantly a pro-am volunteer effort. A team of professional astronomers is primarily responsible for the photometry while a team of amateur astronomers is helping with the equipment, purchased with support from the Robert Martin Ayers Sciences Fund."
