 00:14:38 UT *1, 01:50:45 UT *1

-Started data recording at 00:03 UT.
-Transmitter power was stable (1.4-1.5 MW).
-Sometimes cloudy, but relatively clear sky.
-Disturbed ionosphere between 01:10 and 01:46 UT 
 (See http://polaris.nipr.ac.jp/~yogawa/reimei200611/plot/2006-11-16_arc1_60_all@uhf.png)


2006-11-17 00:00 UT - 2006-11-17 02:30 UT (2.5 hours)
 00:33:22 UT *2, 02:09:19 UT *1

-Started data recording at 00:02 UT.
-Transmitter power was stable (1.4-1.5 MW).
-Mostly cloudy.
-Disturbed ionosphere after 00:00 UT 
 (would be related to Southward turning of the IMF Bz)


2006-11-18 00:00 UT - 2006-11-18 03:00 UT (3 hours)
 00:52:03 UT *2, 02:27:51 UT *1

-Started data recording at 00:00 UT.
-Transmitter power was stable (1.4-1.5 MW).
-Mostly cloudy.
-Quiet ionosphere between 00:00 and 03:00 UT 


2006-11-18 23:00 UT - 2006-11-19 03:00 UT (4 hours)
 23:34 UT *1, 01:10:43 UT *2, 02:46:22 UT *1

-Started Reimei SP at 23 UT due to cancellation of the UK's SP (SP-UK-MISS)
-Started data recording at 23:05 UT.
-Transmitter power was stable (1.4-1.5 MW).
-Mostly cloudy.
-Electron density in the E-region increased between 02:00 and 03:00 UT .


2006-11-19 23:40 UT - 2006-11-20 01:40 UT (2 hours)
 23:53:03 UT *1, 01:29:21 UT *1

-Started Reimei SP at 23:40 UT, but stopped and restarted it at 23:45 UT 
 due to a problem with the Kiruna antenna (acu failed to bring AZIMUTH online).
-Started Tromsoe and Sodankyla data recording (no Kiruna data) at 23:43 UT.
-Transmitter power was stable (1.6-1.7 MW).
-Clear sky, but very quiet ionosphere.
-Sporadic E layer were clearly seen between 00:40 and 02:40 UT, 
 probably due to the Leonid meteor shower.

2006-11-21 00:00 UT - 2006-11-21 02:00 UT (2 hours)
 00:11:49 UT *1, 01:47:57 UT *1

-Started data recording at 00:00 UT.
-Transmitter power was low (0.8 MW) in the beginning, 
 but increased up to 1.7 MW at 00:08 UT. 
 Crowbar occurred at 01:52 UT.
-Mostly cloudy and very quiet ionosphere.


2006-11-22 00:00 UT - 2006-11-22 02:30 UT (2.5 hours)
 00:30:32 UT *2, 02:06:31 UT *1

-Started data recording at 00:01 UT.
-Transmitter power was low (1.4 MW) in the beginning, 
 Crowbar occurred at 00:21 UT when the power was increased up to 1.7 MW.
 Transmitter power was about 1.4 MW between 00:22 UT and 02:30 UT. 
-Mostly cloudy, and extremely quiet ionosphere.


2006-11-23 00:00 UT - 2006-11-23 03:00 UT (3 hours)
 00:49:14 UT *2, 02:25:03 UT *1
 
-Started data recording at 00:11 UT because of restarting the EROS.
-Transmitter power was stable (1.5-1.6 MW), but crowbar occurred at 
 02:46 UT and stopped our experiment at 02:49 UT.
-Mostly cloudy, sometimes clear sky.
-Disturbed ionosphere after 18:00 UT on Nov. 22
 (related to Southward turning of the IMF Bz).


2006-11-23 23:00 UT - 2006-11-24 03:00 UT (4 hours)
 23:31:23 UT *1, 01:07:54 UT *2, 02:43:34 UT *1

-Started data recording at 23:03 UT after UK's experiment.
-Transmitter power was unstable tonight. Crowbar and HV trip 
 occurred at 00:29, 00:35, 00:45, 01:25 UT, and then Power trip 
 occurred at 02:02 UT, so we reset Transmitter and restart at 02:20 UT.
-Fortunately clear sky over Tromsoe.
-Disturbed ionosphere tonight. In particular, electron density in the 
 E region was high after 01 UT.


2006-11-23 23:40 UT - 2006-11-24 01:40 UT (2 hours)
 23:50:11 UT *1, 01:26:31 UT *2, 

-The second priority (Finland's SP has the first priority).


 *1 MAC mode H, no EISA
 *2 EISA mode T and MAC, or MAC pointing observation and EISA
