Important Station Information
Tigo only picked up one scan when it was tagged along to this
schedule file. So, Tigo will not participate in this session
even if their media clears customs in time. The media is
currently being held in Santiago.
===========================================================
There are no observations for Wettzell from 18:15 U.T.
to 19:45 U.T. Wettzell will participate in the
intensive session during this period.
