ISS Transit info

(Finally a thread about a Transit that doesnt involve Venus!)

Many of you will have seen images from people showing the ISS transiting the moon or the Sun. This ( iss-transit.sourceforge.net/TransitAlert.html website allows you to register to recieve an email about when transits are occuring near you.

I find the web page a little confused but it makes sence when it sends you out an email with predictions.
[code:1]
A - travel distance (miles) and direction
B - date
C - time
D - elevation angle of the ISS
E - azimuth angle of the ISS ( + is East from North; - is W from N)
F - range (miles)
G - latitude for observing the transit
H - longitude
I - how far (miles) can I be from the centerline?

For other than solar transits:
J - lunar transits: is space station sunlit?
planetary encounters: 1=Mercury; 2=Venus; 4=Mars; 5=Jupiter; 6=Saturn
K - sun elevation angle
L - sun/moon or sun/planet separation angle

As you can see this does involve you driving many miles to get onto the transit line, and then setting up the scope etc, but an interesting challenge!

Albert, I've seen this in the June issue of S&T, and I too found the webpage confusing, I tried to subscribe, but have'nt got any e-mail back, but it sure is worth a subscription. It wouls be cool to know in advance when the ISS will transit the sun or moon. Could get a nice shot!

I'll try to subscribe again....
