Subject: ACT upgrade at Kiruna

Dear Colleagues,

The receiver at Kiruna (KIRU) has been upgraded to an 
AOA SNR-8100 ACT on 29-SEP-2000 17:38 UT as can be seen
below in the included station information form. Trying
to improve the low elevation tracking performance the old 
antenna has been replaced by a new one (ASH701945C_M).

The hourly data flow has been resumed today after several 
days of testing of the new system.

Best regards.
