The listings on the AO-27 website are not correct at this time....   this
happens every once in a while, where the website gets out-of-sync with the
satellite for some reason (it's about 7 minutes behind right now).

If you use the Java schedule lister instead, written by my son, you will get
accurate listings.  The lister is available to download at
http://sites.google.com/site/ao27satellitescheduler.  Many users here on the
BB will vouch for its accuracy.
