Hi All, I had a very short break in the clouds this morning, just in the right place & right time to spot Superbird A (20040 / 89-041A) & get a timing of it's flash maxima. A break in clouds appeared around 03:12 UT & I spotted Superbird shortly after using 10x50 binoculars. Every second flash appeared somewhat fainter (mag +3 to +4) than the main flashes (mag +2 to +3), so I took these to be secondary flashes & counted the principle (bright) flashes. Counting 10 flash periods I got a period of 23.1s (& of course a period half this if you include the secondary flashes). The flashes increased somewhat in brightness & my impression was that the brightest flashes were at those at 03:16:03 & 03:16:26 UT (5-Aug-1998), although for a minute or two before this time the maxima were also quite bright. I estimate the flashes were easily mag+2 if not brighter. The flashes seemed to fade after this time & I couldn't see them beyond 03:19UT. However, there was still some thin cloud in the area & the twilight was making it difficult to see the stars by this time. Best wishes & clear skies, Jason -- Jason P Hatton INSERM U311 ETS Strasbourg 67065 Strasbourg Cedex France 48.538N / 7.731E / 143m
