Well, I get 06:13 local daylight time for tonight, and the Sun at -7.8 degrees; you might find it in binoculars, since it is just 1-2 degrees left of zeta Orionis while it flashes. On Sep.06 the time has shifted to 06:21 - 25, and the location to above-right from eta Ori; with Sun at -7.7 If the sky where dark enough, a stationary mount should show a single dot. A long-focus lens on a siderial drive may show a nice series of dots, and the varying brightness - but the flashes are extremely short, and I haven't made a calculation on that effect. -- bjorn.gimle@tietotech.se (office) -- -- b_gimle@algonet.se (home) http://www.algonet.se/~b_gimle -- -- COSPAR 5919, MALMA, 59.2576 N, 18.6172 E, 23 m -- -- COSPAR 5918, HAMMARBY, 59.2985 N, 18.1045 E, 44 m -- ----- Original Message ----- From: "Anthony Ayiomamitis" <anthony@perseus.gr> To: <SeeSat-L@blackadder.lmsal.com> Sent: Tuesday, August 28, 2001 10:32 PM Subject: Re: Superbird A is back > Hi Rob, > > Any window of opportunity for Athens, Greece in the immediate > future?
