A significant amount of frozen snow was removed from the sch2 antenna on 2010-01-29 at approximately 21ut.  Data from this station should be used with caution from 10jan25 to
10jan29.  Preliminary analysis shows that the antenna phase center shifted by several cm's due to the snow cover.

I'd also like to thank the CODE AC team for alerting us of this problem.

Brian
