Subject: "Red Dot" Observations in the Southern Hemisphere This is part of the Southern hemisphere geostationary flare program of Jeff Umbarger. His assistance and advice has been invaluable as well as the contributions from Bjorn Gimle and Rod Austin. I propose to observe every night until the "flare" season has passed. Equipment: CoSaTrak 1 200mm f/3.5.8 lens with MINTRON surveillance camera integrating for 128 frames (=2.56s exposure). Mount tracking on shadow entry point ( approx RA12h50m Dec +05deg. Field of view of camera 1.76 x 1.39 degrees, star limit magnitude approx +12.5 mag-when conditions good 11 April 2007 ---------------------- SatName Cat No. Time(UT) RA (J2000) Dec Notes ------------ ------- --------- -------------------- ----- Kalpana 1 #27525 18h59m07s 13h38m50s +05d13'03" Insat 3C #27298 19h00m20s 13h39m56s +05d14'27" Intelsat 4 #23636 19h06m27s 13h37m26s +05d10'46" Eutelsat W5 #27554 19h13m39s 13h37m47s +05d13'06" Intelsat 10 #26766 19h20m50s 13h37m22s +05d14'05" Notes: ------------- Thick cloud and when I had brief gaps had cirrus above the cloud making things rather difficult. Eventually too much cloud so gave up in disgust. Weather conditions still unsettled at the moment so not too confident about tonight but will try if possible. So far no sign of flaring or anything different from previous evenings.
