Craig,  Paul Maley had two days of good flares on northbound morning  passes
See snips below:

correct the area of flare observability. The local elevation and
azimuths of that region were  elevation 35, azimuth 211, phase angles varied 
from 42 to 40 degrees. 

This morning, the same geometry recurred from Houston (26 August 1997
from 10:57:41 to 10:59:32) as the group passed through local elevation
34, azimuth 214 phase angle between 39 and 36 degrees. 

My comments:    I get overhead passes for that time frame but I am not sure
that is correct.  I assume you will get good  flares for 2-4 days very soon.
If you can check yourphase angle AND max elevation pass against what Paul
saw, maybe you can isolate the flare period to a few days.

Paul Maley,  If you could provide the maximum elevation of the passes on
25-26 August, that may help Craig.
