32m antenna observation with low elevation angle was not allowed 
due to high wind speed on the ground (about 20 m/s on average).


04:00 UT

The data was not able to be analysed, so the pulse code was 
changed from beata to ipy which was used for CP run on November 1.

Tx power: ~550 kW

04:30 UT
Direction of 32m antenna was manually changed from zenith to the magnetic field line. 

05:00 UT
One of Tx was heated and the 32m data show strange features in the F-region ionosphere. 
The problem was fixed around 06:05 UT.

~08:35 UT
airport interlock (for ~10 min)

Note: 
Strong wind and cloudy during the ESR observation.

Note: 
A coronal mass ejection (CME) arrived at about 20 UT on November 3, 
resulting in a magnetic storm (Dst minimum of -107).
Relatively weak wind (~8 m/s) and partially clear sky at Longyearbyen 
during the ESR observation.
