Also, I had noticed last week that the beginning of contact time as predicted on N2YO.com was about 4 minutes earlier than the ARISS bulletin had it. Now that it's a few days later, N2YO has an updated AOS time that is much closer to the time on ARISS which hasn't changed. I originally assumed that N2YO would be more accurate than the time posted on a static timeline, but now I'm wondering if ARISS has more insider details than are available from the public TLEs or if N2YO was just using an older data source.
