Here is another OBS. 
 
Does anyone have high-speed photometry of these tumblers?  I feel like I'm 
groping around in the dark down here (no smart remarks about my life, please 
:-)

At the beginning, accuracy was +/- 1.5s, at the end +/- 1s. 
 
Something strange happened near 1 41 20.96.  That flash was faint.  The next 
was fainter.  The maxima became something close to bimodal.  I made a timing 
at 1 41 57.87, but discarded it, because the real maximum occurred at 1 42 
1.30, but in retrospect, I think there were about 3 maxima that were more like 
a Bactrian (two humps) than an Arabian camel (one).  I really don't know what 
to submit for PPAS.  Any suggestions? 
 
Cheers.
