Celestron C11, 2x barlow, Baader > 610 nm, ASI224MC
Stacks: 3500 frames x 100 ms
Seeing is not so good, but the spot is visible.
It is impossible to measure position precisely with such quality of data,
but we have two results with relatively long time interval (august 10 and
22), so I propose a new ephemeris (use it with caution, I can't quarantee
that it is absolutely correct).
Rough estimation:
10.08 2015 22:00 -> 126°
10.08 2015 22:00 -> 76° (average value based on the data of all stacks)
So, drift speed of the spot is about 25.8° per day
WinJUPOS 10.2.0 (Neptune), C.M. transit times, 2015.08.23 14:39
Object longitude: L = 65,0° + 25,8333°/d * (T - 2015 Aug 22,5)
Time interval: 2015 Aug 22,0 ... 2015 Oct 01,0
Output format: Date UT (C.M. of System 1)
