Walking on the Moon

Amateur Observers Are Seeing Double


Recommended Posts

As Derek Breit headed for Fremont, California on April 15 to observe a lunar grazing event, little did he know that he was about to make a discovery that would change the way we look at standard stars.

As he set up his 12" Meade SCT and prepared to record the event with a low lux videocamera, it seemed like a fairly routine observation. Until he reviewed his tapes. As frame by frame moved by, he noticed something a little unusual about upsilon Geminorum - a standard star against which others are measured, especially in the infrared. In 55 frames of his video footage, he apparently captured what may be the very first look at a 11th magnitude companion on a slightly variable star not known to be a double.
