An amateur observer, Derek Breit while observing the moon, 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. This discovery happened as he reviewed his tapes that recorded the lunar gazing event with a low lux videocamera. He did this with his 12″ Meade SCT.
