11683 Cosmos 1154 r was about 1.5 degree to the right of the given
position at 2:37:40, moving in direction 339 to 159 around the point
az 001.5, el 35 (QuickSat 'Dir'), but 198 to 013 azimuth on the horizon.
(I find it much more accurate to give 'Dir', which can be directly
matched to the observer's visual memory or photograph)
06276 DMSP 1-3 rk works well for the same position, being 1.5 degree
left of the the same position, moving 147 to 327 (Dir); 014 to 210 (az).
And 21287 Delta debris fits this POSITION even better, being 0.4 degrees
left, but moving 034 to 214 (Dir); 135 to 344 (az), and it is predicted
to be magnitude +11.
I find none near the lower position even with a reasonable prediction
error, but I only used alldat+molczan from around Nov.10.
