Another clear night with some thin clouds after 02 UT.
Later some small thicker clouds

34839 is a spectacular flasher.
It has bright flares every 2 sec in the middle of along flat max A
on alternating bright flare. The other bright flares were in the
moddle of fainter max a.
There were secondary fainter flares after 2 bright flares.
Pattern: F - (F+A) (f+a)
At first I thought it was an airplane, but predicted and imaged
track fit exactly.

19164 88 043B is Cosmos 1947, a Glonass, in a orbit at 19100 km.
It was seen on 2 images; then not on the next 12 images; then on the next
3 images. So visible for more than 20 sec (10 sec per image); then inv for
less than 130 sec and finally visible for more than 30 sec.
The first 2 were near the edge of the image, so a 3rd is possible.

Yesterday night a UNID was imaged.
Satfit gives: 28492    0.921   -0.036    0.007 17586A    0.979
Residuals: 28492 17 586A   |  0.07094 deg   15.871 sec   1.0 day, 1376.6 km
So a positive ID of Helios 2A.
Cees Bassa confirmed the ID; he has seen it in the same pass.
