The path centerline is near the BD airfield, and Karl is inside the path too. Kirk and I plan to try it from Empire Grade.

I observed from Sunlit Ln, 125 ft SW from the NE edge of the mailbox roof cover which is near Empire Grade. Setting at 4x, gain=41. Clear clean skies, calm. Good conditions except for the moon in the same general direction. I didn't make a note, now a month later I can't remember, if this may be the first time I adjusted the contrast on the 'recording levels' screen; adjusted it downward and the brightness recording level to try and darken the sky but keep the star. This time, on PyMovie the histogram of brightnesses looks quite a bit different. Instead of being artificially cut off at the max number of pixels, now there's a clear peak that is much above this level, and looking rather symmetric too. The star was quite easy to see above the very dark gray sky pixel values as it went through the analysis. Also, just watching the time stamp OCR'ing, it looked to be accurate this time with fewer errors. However, when running PyOTE, there were still a high fraction of OCR errors, even against a black sky. I don't know why my OCR'ing is so poor. Manual time stamps are always required for me, using the Startech method.
A clear 1/2s event.

Looks like a miss for 1998 VO6, Dec. 6, 2x at the Berm. PyOTE detectability tool reports an event as short as 0.150s would be detectable, predicted max was 1.05s.
