I am quite new to this, and only received the ISS on 145.825 on a couple of nights a couple of days ago. The last couple of nights I have heard nothing.

When I look at the "Amateur Radio Stations head via ISS" I see that there has been activity, and today there have been reports of receiving the message "ARISS - International Space Station (BBS/APRS on)". But again no reports in the last few hours, and no stations from Europe reported heard.

Is the packet station being turned off during times when the ISS is over Europe, and if so does anyone know why?

The Fluids Integrated Rack, Materials Science Research Rack-1 and Minus Eighty-Degree Laboratory Freezer-2 were transferred from the Leonardo logistics module and installed in the U.S. Destiny Laboratory.

The newest station crewmember, Nicole Stott, had time to orient herself in her new home, and joined Flight Engineer Frank De Winne for two hours of training related to the upcoming arrival of Japan's H-II Transfer Vehicle, set to launch Sept. 10.
