Tohban Report 09/04/22 - 09/10/22 Tohban Name: Colin Wilkins (updated [9/12/2022]) Special Notes ------------- - The operational plan for the week was to have all ND passes; up to 6 OBO/day on ELA with 2 consecutive with ELB to align with THEMIS conjunctions and one IBO on ELA, with up to 2 OB/day with ELB and 1 IBO/day - A moderate strength storm began on 9/4 and recovered throughout the entire week - ELA data all seems to need a phase delay correction at the time of writing 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 2022-09-12 15:00:06.968439 (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 ------------------------------------------------------ 4 0 1350 323 -12 5.3 Roughly the start of storm main phase; AE activations 4 3 1403 329 -41 5.7 AE activations 4 6 1673 287 -53 6.0 AE activations 4 9 1715 326 -74 6.3 AE activations 4 12 1363 251 -64 4.7 AE activations 4 15 1925 331 -72 5.7 Peak main phase and start of recovery, which lasted all week 4 18 749 110 -64 4.7 ... 4 21 1467 245 -53 5.3 AE activations 5 0 1276 262 -44 5.0 AE activations 5 3 863 203 -44 4.7 ... 5 6 1186 277 -53 4.0 AE activations 5 9 1727 336 -50 4.7 AE activations 5 12 1091 185 -54 3.7 AE activations 5 15 1360 238 -59 4.7 AE activations 5 18 833 186 -48 4.0 ... 5 21 787 188 -41 4.3 ... 6 0 1224 237 -42 4.3 AE activations 6 3 985 193 -41 4.0 ... 6 6 988 176 -40 3.0 ... 6 9 852 146 -41 3.0 ... 6 12 870 150 -45 2.7 ... 6 15 751 130 -46 3.0 ... 6 18 740 167 -35 3.7 ... 6 21 614 118 -32 3.7 ... 7 0 362 72 -25 3.0 ... 7 3 288 54 -27 2.3 ... 7 6 959 242 -34 3.0 ... 7 9 734 220 -36 3.0 ... 7 12 758 171 -34 3.0 ... 7 15 1371 260 -49 3.0 AE activations 7 18 827 178 -51 3.0 ... 7 21 147 23 -31 1.3 ... 8 0 262 53 -23 2.3 ... 8 3 790 153 -29 4.0 ... 8 6 1214 259 -34 4.0 AE activations 8 9 968 276 -36 3.0 ... 8 12 489 104 -36 3.0 ... 8 15 748 152 -30 2.7 ... 8 18 723 128 -33 2.7 ... 8 21 974 182 -28 4.3 ... 9 0 758 151 -38 4.0 ... 9 3 296 57 -34 2.0 ... 9 6 819 247 -28 2.7 ... 9 9 1476 276 -42 3.7 ... 9 12 660 184 -44 2.7 ... 9 15 283 66 -33 1.7 ... 9 18 94 19 -27 0.7 ... 9 21 283 68 -23 2.3 ... 10 0 527 122 -19 2.7 ... 10 3 279 53 -19 2.0 ... 10 6 803 156 -25 3.3 ... 10 9 528 137 -26 2.0 ... 10 12 1066 212 -52 2.7 AE activations 10 15 708 188 -43 3.3 ... 10 18 672 117 -29 3.3 ... 10 21 584 133 -27 1.7 ...
