Tohban Report 07/03/22 - 07/09/22 Tohban Name: Colin Wilkins (updated [2022/7/11]) Special Notes ------------- - The spacecraft were in a low power state due to their orbit, limiting collections - There was a minor storm-like event beginning on 7/4 and a moderate strength storm on 7/7 - The operational plan for this week was 2 OBO/day and no IBO/day with near-consecutive science zone collections between ELA/ELB on the nightside southern hemisphere -- for the data downlinked so far, there aren't any consecutive passes, but presumably they may come down later Abbreviations used: - ORB=Outer Radiation Belt (visible fluxes) - IRB=Inner Radiation Belt (visible fluxes) - PS=Plasma Sheet (visible fluxes) - IB=Isotropic Boundary - 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 Automatic report generated 2022-07-11 15:00:05.257275 (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 ------------------------------------------------------ 3 0 184 29 -7 2.0 ... 3 3 132 24 7 0.0 ... 3 6 94 15 9 0.7 ... 3 9 102 17 22 1.3 ... 3 12 85 15 19 1.7 ... 3 15 101 18 18 1.0 ... 3 18 583 112 3 2.0 ... 3 21 225 34 3 3.0 ... 4 0 335 78 17 3.0 ... 4 3 1146 221 -10 4.3 Onset of minor storm-like event; AE activation 4 6 591 139 -7 4.0 ... 4 9 245 52 -10 3.0 ... 4 12 556 128 -8 2.7 ... 4 15 1159 318 -25 3.3 AE activation 4 18 1195 215 -30 3.3 AE activation 4 21 747 176 -26 2.3 ... 5 0 94 18 -15 0.3 ... 5 3 185 40 -13 0.3 ... 5 6 189 32 -12 0.3 ... 5 9 188 38 -10 0.3 ... 5 12 132 31 -8 0.3 ... 5 15 132 26 -6 0.7 ... 5 18 140 23 -4 0.7 ... 5 21 113 25 11 0.7 ... 6 0 151 28 10 1.0 ... 6 3 163 31 18 0.7 ... 6 6 374 69 14 1.3 ... 6 9 396 73 9 1.3 ... 6 12 170 31 13 0.7 ... 6 15 287 65 8 1.3 ... 6 18 207 33 8 1.0 ... 6 21 122 27 10 0.0 ... 7 0 113 22 13 0.3 ... 7 3 160 30 16 0.3 ... 7 6 283 51 14 2.0 ... 7 9 264 48 29 2.7 Sudden storm commencement 7 12 1377 390 -20 5.3 Begin main phase of storm; significant and persistent AE from here through all of main phase 7 15 1559 258 -52 3.7 Highly active AE 7 18 1707 284 -76 3.3 Highly active AE 7 21 1456 293 -82 3.7 Peak main phase of storm 8 0 1633 273 -71 5.3 End of intense AE activity 8 3 866 237 -57 4.7 ... 8 6 425 69 -30 3.3 ... 8 9 555 154 -31 3.0 ... 8 12 547 110 -34 3.0 ... 8 15 184 40 -37 1.7 ... 8 18 492 115 -25 2.7 ... 8 21 140 24 -15 1.7 ... 9 0 76 18 -15 1.0 ... 9 3 188 46 -16 1.0 ... 9 6 94 20 -15 0.3 ... 9 9 94 19 -7 0.7 ... 9 12 237 52 -5 2.7 ... 9 15 436 81 -15 1.7 ... 9 18 203 38 -17 1.3 ... 9 21 199 45 -15 1.7 ...
