UHF radar observation (beata, CP1)
----------------------------------------------------------

2016-01-05 18:00-28:30 UT

17:12 UT run /kst/exp/beata/beata fm CP1 SP
18:00 UT enablerec
         Tx power : 1.4 MW
18:19 UT crowbar 
01:51 UT crowbar 
04:30 UT stopexp

Note: We extended the SP up to 04:30 UT 
because auroral condition was pretty good.


2016-01-06 19:16-04:30 UT

start the EROS several times.
19:03 UT run /kst/exp/beata/beata fm CP1 SP
19:16 UT enablerec
         Tx power : 1.45 MW
04:30 UT stopexp

Note: It was a clear sky and auroras were seen above Tromsø.
We extended the SP till 04:30 UT because of the excellent condition.
There were troubles with starting the UHF run, and we therefore 
started the run at 19:16 UT.


2016-01-07 18:00-02:00 UT

17:32 UT run /kst/exp/beata/beata fm CP1 SP
18:00 UT enablerec
         Tx power : 1.4 MW
02:00 UT stopexp

Note: It was also a clear sky and auroras were seen above Tromsø.
Electron density enhancements were seen in the EISCAT data between 22 and 24 UT.


2016-01-08 18:00-02:00 UT

Cancelled due to bad weather and geomagnetic activity condition.


2016-01-09 18:00-02:00 UT

Cancelled due to bad weather.


2016-01-10 20:05-02:00 UT

19:40 UT run /kst/exp/beata/beata fm CP1 SP
20:05 UT enablerec
         Tx power : 1.1 MW
21:15 UT Tx power : 1.3 MW
02:00 UT stopexp

Note: We waited for a clear sky and active auroras in the beginning of the SP, 
and then we started the SP when auroras were seen above Tromsø.
Electron density enhancements were seen in the EISCAT data between 20 and 24 UT.


2016-01-11 17:47-04:00 UT

17:38 UT run /kst/exp/beata/beata fm CP1 SP
17:47 UT enablerec
         Tx power : 1.3 MW
19:00 UT Tx power : 1.45 MW
01:43 UT crowbar (UHF & VHF)
03:55 UT crowbar (only VHF)
04:00 UT stopexp

Note: We started the EISCAT UHF run at 17:47 UT because bright auroras were 
seen in the magnetic zenith at Tromsoe. However, weather was very bad for all 
ALIS stations.
Electron density enhancements were seen in the EISCAT data between 17 and 04 UT.


2016-01-12 18:15-02:30 and 03:13-05:00 UT

17:38 UT run /kst/exp/beata/beata fm CP1 SP
18:14 UT Tx ON
18:15 UT enablerec
         Tx power : 1.4-1.5 MW
02:30 UT stopexp

02:37 UT run /kst/exp/beata/beata fm CP1 SP
03:13 UT enablerec
         Tx power : 1.4 MW
03:25 UT crowbar (only VHF)
05:00 UT stopexp

Note: It was a clear sky in Ramfordmoen. Geomagnetic activity was high (Kp =4).


2016-01-13 19:00-01:00 UT

18:09 UT run /kst/exp/beata/beata fm CP1 SP
19:00 UT enablerec
         Tx power : 1.5 MW
22:48 UT strange data recording till 22:52 UT.
01:00 UT stopexp

Note: Some auroral activity occurred in the beginning of SP, 
but it became quiet till the end of SP.


2016-01-14 19:00-01:00 UT

18:32 UT run /kst/exp/beata/beata fm CP1 SP
19:00 UT enablerec
19:03 UT Tx power : 1.4 MW
19:05 UT Tx power : 1.5 MW
01:00 UT stopexp

Note: It became a clear sky at Ramfordmoen and we observed great 
auroral activities at several optical sites (Abisko, Kilpisjärvi, 
and Ramfordmoen) after 20 UT.

------------------------------------------------------------

Summary of the EISCAT UHF runs:
(1) 18-02 UT on January 5-12
      (CP-1 FA mode, beata code, VHF CP run simultaneously.
      We will stop the runs when sky and geomagnetic conditions
      are not good for the campaign.)
(2) 19-01 UT on January 13-14
      (CP-1 FA mode, beata code)
