I noticed this ray when I first started observing the moon 18 minutes prior to the calculated prediction from Akkana Peck’s original observation. I believe it would be possible to observe this ray at an earlier time. It was a very thin shaft of light ~ 60 Km. long. I was only able to observe it for a couple minutes because of very cloudy conditions. I only observed one ray during this period. If there was a smaller second ray, I may not have been able to see it because of very poor seeing conditions. The next opportunity came at 23:10 U.T.; thirty minutes after Akkana’s observation. Again, I was only able to observe it for a couple minutes before the clouds obscured the moon. The ray, by this time, was already a very wide swath of light, which had also lengthened. It was unrecognizable as a ray. There was a shadow of a peak cast onto this wide swath of light. The peak’s shadow didn’t extend to the end of the swath of light. At the calculated prediction time, this peak may have caused the appearance of a double ray, like Akkana’s sketch that she included with her original observational report on this site. My observations may have been too early and too late to see what she observed.
