Tohban Report 12/19/21 - 12/25/21 Tohban Name: (updated by Muhammad Fraz Bashir[12-28-2021]) Special Notes ------------- There were several Strong AE Activations and also a weak storm ( Dst ~-30) on end of 19 December. Both ELFIN A and B observe few interesting events especially ELFIN-A. There were no data/summary plots for Dec 20 from ELFIN A and 23 December on ELFIN B. ELFIN B completions for several intervals about less than 30%. These are times when the auto Tohban report merged two intervals (in summary plots) same as reported last weak 20 December 20:36:44 - 20:55:27 ELFIN B 21 December 17:10:00 - 17:28:29 ELFIN A 18:42:01 - 19:00:26 ELFIN A 22 December 13:19:56 - 13:39:00 ELFIN A 19:28:56 - 19:46:30 ELFIN A 23 December 17:11:29 - 17:30:00 ELFIN A 18:43:31 - 19:01:56 ELFIN A 20:15:31 - 20:33:44 ELFIN A 24 December 11:48:32 - 12:07:26 ELFIN A 13:21:23 - 13:40:25 ELFIN A 17:58:16 - 18:16:44 ELFIN A 19:30:16 - 19:48:48 ELFIN A 11:28:45 - 11:47:34 ELFIN B 25 December 12:16:31 - 12:35:30 ELFIN B 16:54:02 - 17:12:33 ELFIN B Automatic report generated 2021-12-27 16:00:06.578241 (UTC) Note: data is provisional, and may be subject to change Geomagnetic Activity Overview ----------------------------- Day Hour AE (max) AE (sd) DST (min) KP (max) Notes ------------------------------------------------------ 19 0 94 6 16 0.7 ... 19 3 94 7 12 0.0 ... 19 6 94 7 11 0.0 ... 19 9 240 32 9 0.7 ... 19 12 298 54 6 1.7 ... 19 15 940 168 18 3.3 Strong AE activation 19 18 1118 215 -26 4.0 Strong AE activation and weak Storm ( ~-30nT) 19 21 1244 303 -28 5.0 Strong AE activation and weak Storm ( ~-30nT) 20 0 428 96 -18 4.0 ... 20 3 357 78 -21 3.0 ... 20 6 264 48 -21 2.3 ... 20 9 1435 283 -22 3.7 Strong AE activation 20 12 547 105 -19 2.7 ... 20 15 736 116 -26 3.0 Strong AE activation 20 18 268 34 -20 2.0 ... 20 21 372 69 -23 3.0 ... 21 0 466 98 -20 3.7 ... 21 3 208 35 -10 1.7 ... 21 6 243 49 -16 1.7 ... 21 9 258 33 -15 0.7 ... 21 12 905 198 -16 2.0 Strong AE activation 21 15 472 85 -18 1.7 ... 21 18 789 162 -15 3.0 Strong AE activation 21 21 127 14 -8 1.3 ... 22 0 132 14 -7 2.3 ... 22 3 169 20 -8 2.7 ... 22 6 340 80 -16 2.3 ... 22 9 313 49 -13 2.0 ... 22 12 940 271 -15 3.0 Strong AE activation 22 15 458 80 -20 2.0 ... 22 18 482 74 -17 3.0 ... 22 21 289 65 -17 2.7 ... 23 0 198 33 -10 2.3 ... 23 3 94 7 -3 0.3 ... 23 6 75 0 0 0.3 ... 23 9 297 46 -7 0.7 ... 23 12 132 13 -6 0.3 ... 23 15 113 12 -6 0.3 ... 23 18 450 79 -2 1.3 AE activation 23 21 132 15 0 1.0 ... 24 0 94 9 5 1.0 ... 24 3 94 8 5 1.0 ... 24 6 112 12 3 0.7 ... 24 9 372 90 4 1.0 AE activation 24 12 151 16 4 0.7 ... 24 15 281 49 -1 1.0 prolonged AE activation 24 18 298 62 0 1.7 ... 24 21 356 95 -1 2.3 AE activation 25 0 131 12 -2 1.7 ... 25 3 94 9 5 1.3 ... 25 6 642 130 3 2.3 prolonged AE activation 25 9 565 84 -6 1.7 ... 25 12 563 94 -3 2.7 ... 25 15 639 99 -17 1.7 ... 25 18 296 61 -12 1.7 ... 25 21 113 11 -9 0.3 ...
