Pierre said in a DSat message: This evening,interval 96-72A/01-44A should be 2h47.3. Do they wait that W part of Europe completely overcast to perform their pending manoeuvre ? Since the KH orbits are elliptical, and do not have their perigees in the "same" orbital longitudes, the separation in time varies with position in orbit. In my message to DSat 2004-06-13 I proposed a theory that the southbound daylight pass is more significant to determine the time of maneouvre. In that case 2:45 is reached on June 19, using the elsets available at that date. I doubt new elsets would change the time by more than a few hours earlier. I have not verified with earlier occasions, but I know it gave a better result at least once. I had a bad "typo" in that message: If it has moved one day earlier than expected, it will be about two minutes LATE. I don't think I can observe it - weather is unreliable, but above all Sun is at -4 on tonight's 26 deg pass, -6 at the 13 degree pass on June 19 /Björn ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
