    hello everybody,
    
    on 3 oct there will be an annular eclipse for central spain at 08:58 UT, 
    details about which can be found in this sky and telescope article:
    
    http://skyandtelescope.com/observing/objects/eclipses/article_1593_1.asp
    
    I have friends in madrid who are keen on observing the event.  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!
