===========================================================
Important Station Information
This session has mixed bandwidths since Fortaleza is
included. Fortaleza is using 4 MHz.
Ny Alesund was tagged along to this session.
Since Seshan has only 8 BBCs, there are only
4 being used at X and 4 being used at S. A total of 9
channels are being recorded because one of the X-band
converters is used for both upper and lower sideband.
===========================================================
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.
