Hello everybody, This is an event very hoped and my group of astronomy is going to Madrid to make the observation of the eclipse. We have many curiosities because, because it is not a total eclipse, we do not know what magnitude will have obscuration of the surroundings and if it is possible to see some of the most shining stars, planets and of course this includes LEO objects. will the sky darken enough at the peak of the event to allow for naked-eye observations of LEO objects? <-- That is the great question. I am enough skeptic and I don't believe that it is going to be possible. I don't believe that we see more of Sirius or Mars. Simullation with the Starry Night doesn't give rise to great hopes. If any of you have experience with this kind of event, please advice me and tell me the experience.

I read the recent discussion (18 sept) between russell eberst, daniel deak, and gerhard holtkamp, and I have the following questions: will the sky darken enough at the peak of the event to allow for naked-eye observations of LEO objects? how can I get predictions for if and when such objects might be visible? using starry night pro (which doesn't list too many LEO objects) for example, I notice iridium 7 is in the area at the time of the peak. will it be obscured by the umbra for the entire time it's in line-of-sight with madrid? I notice also, using the amateur radio predictions from HA, that the mother of all bright sats, the ISS, unfortunately won't be making a pass at the time of the peak. is there any way to tweak HA or Calsky in order to show any illuminated LEO objects which might be visible from madrid at the time of the peak? if not, would someone kindly kick me a list of predictions? ( I noticed mr. holtkamp has offered to do so for geostationary objects.) I suppose if I got really ambitious I could fire up my STK software and use data from calsky, but I'm fairly slow at that type of thing and probably would commit a fundamental error somewhere. I hope one of you veterans can whip this problem with more ease. it's likely these observations will prove impossible from my friend sara's office (one block south of estadio santiago bernabeu, 40.4504N, 3.6877W ) because these objects will obviously be in the shadow when overhead, and also viewing would be complicated by the high buildings and air contamination in that part of the city. mr. iruretagoyena , should you read this, if you are in zaragoza at the time of the event, I'd sure appreciate an account from you. clear skies! stephan szyman chicago IL USA 41.6840N, 87.7000W; 188 msl ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
