According to various sources, the ISS orbit was raised 1 km Thursday. This will result in a "slippage" of the old Kep's predictions of about 20 seconds per day. So make certain your Keps are up to date. The Celestrak updates used by most tracking programs look good.

That may explain why last night I showed an 88 degree pass for tonight, that now shows as 66 degrees
