Because the ISS can be viewed very clearly in June/July with the naked eye, a Dutch journalist and a Dutch astronomer have started a service on twitter to let people know when the ISS passes over their location.

According to NASA ISS Ham Radio Project Engineer Kenneth Ransom, N5VHO, there is a good possibility that groups participating in ARRL Field Day may be able to make a contact with one of the astronauts aboard the International Space Station (ISS).

"Some of the crew members of the International Space Station plan to make contacts with operators on the ground during Field Day operations as time permits" Ransom said. "Since the ISS now has a multinational crew representing all five space agencies, the possible club call signs to be heard are RS0ISS, NA1SS and OR4ISS. The crew could also elect to use their personal calls, as well. In either case, they will be signing 1A (Alfa) ISS after the call sign."
