Hello Stephan, On Jan.17 the drag terms suddenly increased 50%. This has a marked effect causing culmination to be lower in the SE. From then on, drag has slowly decreased towards normal values, so I think you can be quite confident. I checked NASA's 'future TLE's' to get their opinion - today the last elset given is for Feb.02 and gives 64 degrees alt. at 19:43:35 UTC+1. (Somewhat surprising though, since they show a higher drag than past elsets. But it's only 11 days, and halving the value results only in a delay of 8 seconds, and four degrees HIGHER) 07033.ISS 1 25544U 98067A 07033.56297412 .00020000 00000-0 20000-3 0 9110 2 25544 51.6328 79.6967 0021746 159.9391 200.2634 15.77781007 29515 http://spaceflight1.nasa.gov:80/realdata/sightings/SSapplications/Post/JavaSSOP/orbit/ISS/SVPOST.html ----- Original Message ----- From: "Stephan Szyman" <szymanss@hotmail.com> > > I am hoping to demonstrate a high, bright pass of the ISS to an audience > at the planetarium of madrid, spain, on or around the evening of the 13th > of february (weather permitting, of course). > > I have been watching predictions for the pass of that evening since the > beginning of this month. on 1 jan HA predicted the maximum elevation of > the pass to have been 75 degrees, occurring at 19:48:43 local time. ... > > today, 21 jan, HA shows 63 degrees at 19:42:30. > ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
