Observer: PJ Anway Date/time of observation: 2003/04/12 01:45 U.T. Site location: Munising, MI, USA (46.23° N., 86.40° W.) Seeing: 7/10 Conditions: 35°F, light breeze Age: 10 days 6 hrs Instrument: 8" f/7 Newtonian Magnification: 177X (Zeiss 8mm ortho) Image: Nikon Coolpix 990 through Zeiss 8mm ortho I had intended to image Promontorium Heraclides (the lady in the moon) just as her face came out of the shadows, but one look and I knew that the seeing would make a decent shot difficult. However, as I examined the 260km crater Sinus Iridum, I noticed that to the northeast a lunar ray was emerging from Promontorium Laplace and proceeding westward across the crater's face. Under brief periods of good seeing, the wedge of light was very distinct and I estimated it to be about 27 miles in length (using Lunar Map Pro). In the image I did take, the poor seeing is quite evident, but the ray is there and it looks like the "lady" has the best view.
