---------------------------------------------------------- KST observations (updated on November 19, 2012) ---------------------------------------------------------- ---------------------------------------------------------- SP_DUA_PA PIs:K. Shiokawa (STEL, Nagoya Univ.) Y. Miyoshi (STEL, Nagoya Univ.), T. T. Tsuda (NIPR), and S. C. Buchert (IRF Uppsala) Resources: NI(44),SW(40) UHF radar observation (beata, field-aligned) VHF radar observation (manda (v4), vertical) ---------------------------------------------------------- 2012-11-13 (Tue) 21-06 LT (20-05 UT) (UHF and VHF) ( 9 hours) (UHF) Continued a previous run (with beata near FA direction) 20:00 UT pointdir 186.2 77.5 05:00 UT stopexp (VHF) 19:50 UT runexp /kst/exp/manda/manda fm zenith SP 20:00 UT enablerec 05:00 UT stopexp High geomagnetic activity and mostly clear sky at Tromso. Data analysis of VHF radar cannot catch up with real-time, mainly due to heavy load of PCs. ---------------------------------------------------------- 2012-11-14 (Wed) 21-06 LT (20-05 UT) (UHF and VHF) ( 9 hours) (UHF) 19:50 UT runexp /kst/exp/beata/beata fm cp1 SP 20:00 UT enablerec 23:57 UT crowbar (0 kW) for 30sec 05:00 UT stopexp (VHF) 19:50 UT runexp /kst/exp/manda/manda fm zenith SP 20:01 UT enablerec 23:57 UT crowbar (0 kW) for about 30sec 05:00 UT stopexp Quiet geomagnetic activity and mostly cloudy at Tromso. Problem of the VHF data analysis was fixed. Tx powers: 1.8 MW for UHF and 1.5 MW for VHF. ---------------------------------------------------------- 2012-11-15 (Thu) 21-06 LT (20-05 UT) (UHF and VHF) ( 9 hours) (UHF) continued a previous run (with beata near FA direction) 20:00 UT pointdir 186.2 77.5 05:00 UT stopexp (VHF) 19:50 UT runexp /kst/exp/manda/manda fm zenith SP 20:00 UT enablerec 05:00 UT stopexp It was mostly cloudy at Tromso. Ionization at about 80 km altitude due to high energy precipitation occurred at 20-20 UT and after 03 UT. Tx powers: 1.7 MW for UHF and 1.5 MW for VHF. ---------------------------------------------------------- 2012-11-16 (Fri) 21-06 LT (20-05 UT) (UHF and VHF) ( 9 hours) (UHF) continued a previous run (with beata near FA direction) 20:00 UT pointdir 186.2 77.5 22:39 UT crowbar (0 kW) for about 2-min 05:00 UT stopexp (VHF) 19:50 UT runexp /kst/exp/manda/manda fm zenith SP 20:00 UT enablerec 22:39 UT crowbar (0 kW) for about 2-min 05:00 UT stopexp It became clear sky after 2230 UT and several types of auroras were seen (e.g., Diffuse aurora after 0230 UT). Tx powers: 1.4-1.5 MW for UHF and 1.5 MW for VHF. ---------------------------------------------------------- 2012-11-17 (Sat) 21-04 LT (20-03 UT) (UHF and VHF) ( 7 hours) (UHF) continued a previous run (with beata near FA direction) 20:00 UT pointdir 186.2 77.5 23:28 UT crowbar (0 kW) for about 1-min 01:04 UT crowbar (0 kW) for about 1-min 01:21 UT crowbar (0 kW) for about 1-min (only UHF) 02:35 UT crowbar (0 kW) for about 1-min 02:58 UT crowbar (0 kW) for about 1-min 03:00 UT stopexp (VHF) 19:50 UT runexp /kst/exp/manda/manda fm zenith SP 20:00 UT enablerec 23:28 UT crowbar (0 kW) for about 1-min 01:04 UT crowbar (0 kW) for about 1-min 02:35 UT crowbar (0 kW) for about 1-min 02:58 UT crowbar (0 kW) for about 1-min 03:00 UT stopexp Mostly cloudy after 20 UT. Tx powers: 1.4-1.6 MW for UHF and 1.5 MW for VHF. ---------------------------------------------------------- 2012-11-18 (Sun) 21-01 LT (20-00 UT) (UHF) ( 4 hours) (UHF) 19:50 UT runexp /kst/exp/beata/beata fm cp1 SP 20:01 UT enablerec 24:00 UT stopexp Completely cloudy after 20 UT. ----------------------------------------------------------
