Four ftp tests are scheduled: (1) 11:09:38 UT (scan 2, 2 sec, J1800+3848) (2) 11:51:58 UT (scan 11, 2 sec, 1922+155) (3) 13:11:38 UT (scan 27, 2 sec, 1922+155) (4) 13:53:38 UT (scan 35, 2 sec, J1800+3848) Please make sure that the autoftp is set up correctly. Good luck with the session and see you on Skype!
