Accurate ISS pass times- who is correct?
In trying to determine when the ISS passes over my house, I am noticing a discrepancy between the two sites I normally use to get the pass times; here and Heavens-Above. Below are extracts from both sites; anyone know which is really correct and why one is so far off?
ISS Fan Club data
12 Mar 02:32:32
12 Mar 04:06:57
12 Mar 05:43:50
12 Mar 20:35:35
12 Mar 22:10:07
12 Mar 23:48:00
They are both calculated for the same location in south New Jersey. Any thoughts appreciated.
I suspect the data from here is more accurate, but I'm not sure.
