Fitting a circular orbit to this gives the following:

inclination 141.522 degrees, period 92.89 minutes, height 419 km
RA Node 292.8 degrees, epoch 017007.7515 , revs/day = 15.5023
Looks like an Ofeq satellite ?   About mag +3.5 as it moved
westwards.

NOTES:
--------
(1) Prime purpose of session was to try the several element sets
     given by Bjorn a few days back for USA 188. Nothing seen
     that could be USA 188 a few minutes either side of
     predictions so looks like USA 188 is well and truly lost.
     However I have not given up yet and will revert to doing
     plane scans now that I have a sort of working system again.

(2) All the above satellites seen by accident when they crossed
     the field of view.

Cheers
Greg
