Almost Nothing

24 hr Moon
image by Riccardo Di Nasso

Seeing the Moon before it is 24 hrs old has become a competitive sport, with Stephen O’Meara being the apparent champion with a record of 15 hr, 32 min. On June 7, 2005, the less than one day old Moon was once again a challenging and frustrating target. For many observers clouds interfered, and for others the lack of contrast between a nearly setting Moon and a hazy horizon made it impossible to find. But Italian photographer Riccardo Di Nasso was prepared and lucky. In his image, just beyond the clouds, and only 2.5 degrees above the Tirrenum Sea, is the broken crescent of a 21 hr 45 min old Moon. The thin spots in the pencil-width crescent are where the darkness of maria Marginis, Smythii and Australe reflect little sunlight.
