Tohban Report 09/11/22 - 09/17/22 Tohban Name: Colin Wilkins (updated [9/19/2022]) Special Notes ------------- - This was the final set of ELA-A collections before the satellite de-orbited on 9/17 (bittersweet times!) - The operational plan for the week was to collect up to 4 ND OBO/day and 1 IBO/day on each S/C consecutively, with EL-A being spread evenly throughout the day (until no longer possible), with EPD-I being out of dayglow - There was also a special request to collect data on 9/10 for a conjunction with THEMIS and MMS - There were no major geomagnetic events in this interval Abbreviations used: - ORB=Outer Radiation Belt (visible fluxes) - IRB=Inner Radiation Belt (visible fluxes) - PS=Plasma Sheet (visible fluxes) - IB(s)=Isotropic Boundary (e=electron, i=ion) - prxn=precipitation - LE=low-energy (~500 keV or less) - ME=medium-energy (~500 to 1000 keV) - HE=high-energy (~1 MeV or greater) - SAA=south atlantic anomaly - NS=nightside - DS=dayside - HL=high-latitude - SEP=solar energetic particles - S/C=spacecraft Automatic report generated 2022-09-19 15:00:07.536280 (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 ------------------------------------------------------ 11 0 337 71 -22 3.0 ... 11 3 117 20 -21 1.7 ... 11 6 207 36 -14 1.3 ... 11 9 496 112 -13 2.0 ... 11 12 424 81 -20 2.0 ... 11 15 962 182 -23 3.0 ... 11 18 542 99 -25 2.0 ... 11 21 358 83 -20 1.3 ... 12 0 466 109 -18 2.7 ... 12 3 452 77 -21 2.7 ... 12 6 789 133 -23 2.7 ... 12 9 716 125 -16 2.0 ... 12 12 490 94 -16 1.3 ... 12 15 188 31 -11 0.3 ... 12 18 358 74 -9 1.3 ... 12 21 112 19 -7 0.7 ... 13 0 113 19 -16 0.0 ... 13 3 94 20 -11 0.7 ... 13 6 388 83 -9 1.3 ... 13 9 314 63 -13 0.7 ... 13 12 153 32 -10 0.7 ... 13 15 235 46 -2 0.7 ... 13 18 113 18 1 0.0 ... 13 21 111 20 -1 0.7 ... 14 0 113 23 -4 1.0 ... 14 3 111 17 2 0.7 ... 14 6 107 18 -1 1.7 ... 14 9 185 31 6 1.3 ... 14 12 336 70 4 1.7 ... 14 15 381 59 15 1.3 ... 14 18 464 90 18 2.7 ... 14 21 547 103 -22 4.0 ... 15 0 606 151 -23 3.7 ... 15 3 127 27 -16 0.7 ... 15 6 102 19 -13 0.7 ... 15 9 109 19 -9 0.3 ... 15 12 127 21 -9 1.0 ... 15 15 158 24 -2 2.0 ... 15 18 132 20 5 0.7 ... 15 21 119 16 5 0.7 ... 16 0 113 18 5 0.3 ... 16 3 94 13 3 1.3 ... 16 6 108 16 6 1.3 ... 16 9 120 22 7 1.3 ... 16 12 148 20 1 0.3 ... 16 15 208 40 -4 1.3 ... 16 18 131 23 1 0.3 ... 16 21 113 17 1 1.0 ... 17 0 104 16 0 0.7 ... 17 3 94 17 3 0.0 ... 17 6 127 24 5 0.7 ... 17 9 204 36 1 1.3 ... 17 12 226 49 3 1.7 ... 17 15 113 18 10 0.3 ... 17 18 202 30 5 1.0 ... 17 21 349 62 -4 2.0 ...
