Mike,
High and low power refers more accurately to power consumption rather than transmitted power. Low power means a less than 100% duty cycle. Many of the popular tracking programs such as SATPC32 and MacDoppler will tell you when the satellite is in daylight or eclipsed. A spacecraft is often illuminated when the ground track is in darkness, though the passes you mentioned would be in eclipse.

Whats the difference between high and low power mode? I know its determined by being in eclipse or not and I believe high power is 0.5 W on SSB and FM. But no luck in finding more info than that on the web about power.
So far, all passes I've been able to copy here Eastern US are late at night (11PM-1AM) so I'm assuming I'm getting low power mode.
