Should you be near an eyepiece right now (8:17pm PDT) there's quite a spectacular ray in the crater Barrow (Rukl 4). Move fast...
I saw this ray from a street corner of San Francisco tonight. We were doing some Sidewalk Astronomy in a friendly neighborhood of the city - the only spot not enveloped in fog! I brought my Rulk Altas with me, and was using my 10-inch f/7.3 homemade dob, Stardust. I also enjoyed the shadows and while not exactly a ray, a wedge of light on the crater floor of Maurolycus (Rukl 66). The shadows in Gemma Frisius/Goodacre (same map) made this crater rally stand out. So much so that more than one of the hundred folks who took a look asked me what the name of that particular crater was!
