Observer: Tony Donnangelo Date/time of observation: 2003/02/10 00:05 U.T. Site location: Hummelstown RD 3, PA, USA (40.26° N., 76.75° W.) Site elevation: 479 feet (146 meters) Site classification: Suburban Instrument: Takahashi FS-102 Magnification: 91x(9mm NaglerT6),158x(Pentax 5.2mm XL), 234x(3.5mm Vixen SW), Moon's age: 8d 13:15, 55% illuminated Object: Goldschmidt (walled plain) Size: 120Km.x120Km. Lunar ray coordinates: 02.0°E., 74.75°N. Rukl chart #: 4
I observed this ray as a narrow shaft of light ~55Km. long. The ray had a dark shadow completely cutting across it, making two segments approximately the same length. I believe this was caused by a craterlet inside Goldschmidt near the northern rim.
Conditions were cloudy during the whole night. However, I observed it periodically over the next 1 1/2 hours. It remained the same over this period. It became too overcast and I called it a night. It may be possible to observe this ray at an earlier time, and it probably could've been seen, after I made my last observation.
