I got, as a surprise, the NanoSail-D2 into may fireball camera. This is 2 minute a peak-hold image made with computer from real time video data with the camera:
It is taken at 17:32-17:34 UT.
Vega (about the same magnitude as N.S. maximum) is seen to the lower left in the image and Ursa Major at rigth. Polaris up center.
The second image is a comparison "screen copy" from Heavens Above. Times in it are for timezone UT+2.
