hi all! yesterday, at 23:39:30 UTC plus or minus 15 seconds, I observed an object which appeared against daylit sky, flaring, fading and flaring again as if a tumbling object but seeming very similar in appearance to an iridium flare. the object moved from right to left, paralell to the western horizon at approximately 280-285 degrees azimuth when i first spotted it and flared quickly twice or thrice before i lost sight of it... it then flared less brightliy but was visible again for a short time after that, perhaps for 8 or 9 seconds; this all took place above and slightly to the left of the sun's position in the west, at an altitiude of between 28 and about 35 degrees. I checked HA to see if there were any predicted daytime iridium flares. but nothing was listed, and I've never seen an iridium flare multiple times over a 30-second-or-so span as this object did. checking calsky, I cannot figure out how to get it to show objects crossing during daylight... this was possoibly an aircraft, but i believe I would have been able to make out a shape or at least a small dark spot, depending on the distance and altitude of the aircraft, but i saw neither. i'd love to read instructions about how to ID daytime events like this, either using HA or calsky, if it's possible, and wish to know the identity of that object. clear skies! stephan szyman chicago IL USA 41.6840N, 87.7000W; 188 msl _________________________________________________________________ http://imagine-windowslive.com/hotmail/?locale=en-us&ocid=TXT_TAGHM_migration_HM_mini_pcmag_0507 ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
