Station Comments
----------------

TSUKUB32(T-Ts): OK
                Recorded on K5(VSSP32). 

WETTZELL(V-Wz): Lost 10 scans (061/07:30-07:47) due to 
                the power failure by the thunderstorm.
                Recorded on Mark5.

- comment:
Intensive eVLBI session with TSUKUB32 and WETTZELL.
Recorded Data on Mark5 at WETTZELL were transferred
to Tsukuba Correlator via network. 
Converting Mark5 data into K5 form at Tsukuba Correlator. 
Processed on K5 correlation system.
