On Aug.04 (-97) at about 20:48:30 UTC while waiting for #24805 I saw
a mag. +1 flash, followed by more similar. I picked it up in 7*50
- it was almost invisible between flashes, but they were not the
on/off type, but quite rounded maxima. 

It was moving above (?) Hercules in direction 085 rel.to the horizon
and took 17 seconds to cross the 7.1 degree FOV just before culmination.
Later, it crossed midway zeta/eta UMa, in direction 120 degrees r.t.h.
Unfortunately, I did not take exact time there.

The flash/speed measurements were 20:48:50.7 - 20:49:08.1 UTC

The flash periods were multiple, possibly 2.5 / 2.3 / 4.5 seconds (?)

This was a beutiful beacon.
At 21:48 Local Standard Time and lat. 59+ the skies were still quite
bright, and I missed #24805 (1-power), as I missed #24680 (7-power)
forty minutes earlier.

By molczan.tle it appears to be #22823 Spot 3.
Can anyone confirm this by visual appearance ?

If this one is spinning with Earth-orientation, look for flashes at
the same local time and position ( 60 deg above W )
If it is free-tumbling, look at the same starfield whenever it
passes there - if flashes elsewhere, we may guess the spin axis.
