IGS 1A was 116 s early on this elset (site 5919). Although I am not certain about these splits, the first one was done at 1-power between zeta and eta Uma, and the last one was in a tight pair of rather bright stars (inclination may be higher?). And I couldn't find any match for my third split! -- 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: "Ted Molczan" <molczan@rogers.com> To: "SeeSat-L" <SeeSat-L@satobs.org> Sent: Friday, April 25, 2003 5:27 PM Subject: TJM obs of 2003 Apr 25 UTC; IGS 1A and IB elements > As expected, IGS 1B manoeuvred; it was about 1.5 min early.
