Subject: SFER new but provisional antenna

On day 365 the SFER permanent tracking station TRIMBLE L1/L2 with Ground
Plane antenna has been changed provisionally for a CHOKE RING DORNE
MARGOLIN TRIMBLE.. We will back to the old configuration in a few days and
we will mail it then. Please take a look of the new log file I join.

I apologize for the inconveniences. Best regards and Happy New Year.
