===========================================================
Important Station Information
Kokee will be running warm during this session. So the SEFDs
were increased by a factor of three for X-band and a factor of
two for S-band.
===========================================================
There are no observations for Kokee and Wettzell from 18:15 U.T.
to 19:45 U.T. Kokee and Wettzell will participate in the
intensive session during this period.
