Todays exercise was to try and catch both ISS and the orbiter in daylight.....with the sun 37 degs above horizon. At 17.06.53 BST ISS was due to pass by at 55.4 degs elevation mag -2.8 , the shuttle was due to follow at 17.07.19 according to Calsky ...elevation again , 55.4 degs , but mag 0.2 ( 26 seconds behind ) I was confident ISS would be vis as 90 minutes earlier I had seen it mag -2.2 with the sun at 50 degs , but the shuttle was another matter. As it turned out , both turned up on time.....and Discovery "was" just visible. Quality of images is poor again due to focus problems and shimmering in the OTA.. FOV about 7 x 4 arc minutes http://mysite.wanadoo-members.co.uk/satcom_transits/ISSSTSdaylight.gif Further details shortly John UK Any images attached are subject to copyright restriction but may be used with prior permission ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
