Meton Lunar Ray Confirmation Report I helped a friend wring out his new ITE DeepSky Pro video camera on the night of 2003/2/9 UT. The location was north of Harrisburg, Pennsylvania. The relative humidity was a miserable 65% and the temperature was -14 degrees Celsius or less. All told I spent about 5 hours outside imaging the moon, Jupiter, and numerous deep-sky objects using the camera and a 12" Meade LX200 SCT working at f/6.3. The Meton Lunar Sunrise Ray (Rukl #4) was seen using a 12.5mm orthoscopic eyepiece (154x) but not on the video monitor or the videotape upon playback. Tony Donnangelo had called us earlier to alert us to this new lunar ray. Dave Mitsky
