Satellite predictions mis-match

Posted by BC on May 20th, 2008

   Discussing sky events and other astronomy-related things is what keeps me in touch with my astronomer friends. One day Mark Cunningham and I were talking about the up-and-coming multiple ISS passages, when we disagreed on some details. I was going off the information from Spaceweather’s satellite tracker, and he from  NASA’s human space flight.  After investigating the details, I found discrepancies between the two sites in the number of dates when ISS could be seen. The NASA site had more times, but there may be an explanation for the difference between the two sites that I have not found yet.

   Both sites are credible, but if you cannot access reports for your particular location on one, try the other.
