At 0445 UTC (1945 PST) the ISS was off the East coast of Africa. Might check your tracking program against a few others to verify its accuracy.
This one is usually a good site to check against. http://spaceflight.nasa.gov/realdata/tracking/index.html

I'm not sure what 1945 PST is in UT, but I heard the ISS today at 11:44
NZ summer time (22:44 4 Nov UT) and 1323 NZST (0023 5 Nov UT).
The digipeater was active on 145.825 MHz.
I find the only reliable way of determining the operating frequency is
to listen. That said, packet is now almost always heard on 145.825 MHz.
If it isn't, it usually means the gear is turned off, but it can mean
that that other modes are active, and it's worth tuning around the
The site www.ariss.net shows that the ISS gear is currently active in
the digipeater mode.
