ISS Transit Jan 15th was created by albertw
Hi,

During the ISS passover on January 15th, according to iss-transit.sourceforge.net, the ISS will transit the Moon during the 18:42 pass from around Dun Laoghaire. The actual coordinates it gives are for roughly the middle of Dun Laoghaire harbour!

This should however be visible for a radius of a couple of miles.

This is the first time I've seen the possibility of a transit of the moon from within Dublin.

I'll update with more accurate predictions when I get them.

Cheers.

Based on the orbit details spaceflight.nasa.gov/realdata/sightings/...rbit/ISS/SVPOST.html

It looks like the pass on the 15th will transit the Moon from latitudes Loughlinstown to Bray. What longditudes I dont know.

Cheers,

Could you go out the piers in Dun Laoire if you had to, very windy though.
The moon will be a cresent, will the ISS pass over the dark side, and then onto the bright side. ???

According to www.calsky.com/ it appears that there is another ISS transit of the moon from North Dublin on Thursday at 19:23. The centre line appears to cross the Airport, and the path width is about 17km, which means that the whole northside, and some of the southside, should see the event. This seems to be a good event - the ISS is predicted to take almost 4 seconds to cross the moon, largely because the event takes place only about 10 degrees above the horizon.

Looks like a few satellites transit the moon around the same time as ISS.

Looking at Starry Night Pro (and how precise that is I don't know but I did just update the position files) the transits for Bray are:

18:41 "SOYUZ-TMA 5" mag 0.71
18:42 "PROGRESS-M 51" mag 0.7
18:43 "ISS" mag 0.69

Specifically www.calsky.com/cs.cgi/Satellites/4

These transits of the Moon and Sun occur fairly frequently, since I've been waiting for a pass to occur near me I've noticed that there is a lunar transit almost biweekly around Dublin or Wicklow.

Solar transits seem more rare. I've only been near the path for one in the last couple of months, and yep, you guessed it, it was cloudy.
