Hi all,


I observed visually and photographically the pass of 2015-019-B rocket this morning on 23 March 2016.
The appulse to Epsilon Boo occurred at 3h57m09s UTC compared to 3h56m47s UTC according to Calsky.
Hence it was 22 seconds late according to a Calsky ephemeris that predicted decay for today 23 March 12h01m TU


Tonight the brightness variations were not obvious , the satellite being mainly of mag 2.5-3.5 in CVn, Boo and Ser.
On 21 March at 23h04-07 UTC the variations were spectacular and the photometric period was derived from the photos at:  18.0 +/- 0.3 seconds.



Regards


Alain
