The acceleration of 92- 30 J I mentioned in my message of yesterday seems not to 
continue. As you can see from the above DRA-obs there is a lot of difference on the 
induvidual flashes.
Flash 1 to 3 are 13.3 - 13.4 sec
Flash 5 and 7 are high, flash 4, 6 and 8 are low; this equals out to 13.46 sec.
Flash 9 to 12 are high: 13.72 to 13.87
Flash 13 and 14 equals out to 13.42 sec.
Flash 15 is high due to a late timing as flash 16 came early: mean time 13.6 sec.
Flash 17 is rather high.
Flash 18 and 19 are almost on the average flashtime.
I followed the sat over most of it path visible from my backyard; over an estimated 120 
degrees. The gradual rising of the period during the pass is due to the synodic effect, 
but the induvidual differences of the flashes must have to do with the satellite's 
shape.

Greetings and clear skies
