Morning All, Re the availability of the SDP4 code. After seeing Rob Matson message giving the location of this site I typed the full address is as given and was unable to access the area. I then decided to explore the site and started with the main address, then directory by directory found out what there was- eventually I arrived at the SDP4 code and the rest of the prediction software and the address was exactly as Rob had given it, so it looks like the site doesnt "like" a long address but if you go directory by directory, as given in the address, you will access it with no further trouble. Many thanks to Rob for the address, and also for the Iridium flare software. 96072A has started evening visibility here -currently getting up to about 14 degrees elevation before shadow entry so once I get off my butt and set my scope up again Ill keep a watch on it- anyway this past weekend was no good with late evening cloud hiding what few stars one can see from Cape Town. Cheers Greg
