Hobart recoded to 2 types of disk media. Xraid @ 256 Mbps AND Mark5a @ 512 Mbps.

Xraid data on curtV012A1-7_p2 first 12 hrs then curtV012A1-7_p3 for second 12 hours. This disk set also has data from experiment v252h and so will be sent to Curtin.

Mark5A diskpack MPI-0519/4000/1024 will be sent to Bonn using DHL once Chris says. For the moment the Mark5A disk pack will stay in the recorder at Hobart. This disk pack also contains the VC067 fringe check experiment data at the start. 3.3TB total were recorded on the Mark5 module. 3,283,765,272,448 bytes. This disk pack also contains the VC067 fringe check experiment data at the start.

Between the times of 223/2238 till 223/2335 the serial comms to the receiver were hung up and there was no tsys data AND the noise diode was ON.
