Seanie, that's low and high in terms of the horizon, not the ground.

The ISS is in an orbit inclined to the equator by 51.8deg, thus the highest latitude where it can appear directly overhead is 51.8deg N - ie just North of London. At higher latitudes it will appear in the southern part of the sky to a greater or lesser degree - here in Larne it never gets more than 43deg above the horizon - you'll do better where you are. Some of the current and upcoming passes are as high and bright as they come!

Ah right, I know what you mean Paul, but never thought of it like that in terms of 'altitude'. Thanks.

oops my heavens above settings were somehow wrong.
There is an 84 degree altitude pass on 22 May at 5.01 am, I've never seen it so high, but almost all of the other passes between now and the end of May are very low with only 4 out of the 35 or so passes reaching a decent altitude, but if you have a flat southern horizon, go for it.

but what a way to go. :)
