Mike Mccants reports obs of Superbird A from Florida (USA east coast)
on 8 Feb 97 at about 0300 UT.

I am assuming from previous obs that flashing ( if observed) will
occur about the same time throughout the US.

I will leave it up to the folks analyzing this satellite to determine
what they need in obs, however I assume that a period as well as a 
few accurate flash times are in order.

Expect a period (bright flash to bright flash) of about 23.4 seconds.
During the obs last fall from the western US, secondary flashes were
also observed.   On one of my obs,  I detected (not confirmed) a shifting
of the bright flash by 1/2 period.  I ASSUME that this may be due to 
the changing sun angle which reflects more directly off the second array.

Included are recnts elements for Superbird A.  Since the flashes are
reported at 4-5th magnitude, binoculars would be adequate for the 
brighter flashes. Use of a telescope will allow sightings of fainter
