Solar array angleA plot of the solar array angle at the time of ACA high background events shows that there is no strong correlation. The plots below show the SA angle versus time and versus the "strength" of the high-background event. There is a slight hint that in recent years the high-background events occur less frequently at mid-range pitch angles, but the statistics are not conclusive.Momentum Dumps"Strong" events (strength >= 50)Hi Bgd Time Strength Mom Dump Time A1 A2 A3 A4 Delta_T ----------------- ------ ----------------- ----- ------ ----- ----- ------- 2001:111:00:25:36 737.9 2001:100:01:35:01 433 0 540 117 1 2001:126:13:08:46 660.0 2001:126:12:05:02 355 0 740 240 1 hr 2001:126:22:17:36 344.4 2001:126:12:05:02 355 0 740 240 10 hr 2001:176:19:12:16 65.6 2001:070:23:43:01 0 124 320 282 6 2001:182:10:27:16 399.7 2001:167:11:00:02 0 720 342 365 15 2001:182:10:32:26 153.7 2001:167:11:00:02 0 720 342 365 15 2001:185:02:23:06 299.3 2001:185:01:50:02 940 0 177 625 < 1 hr 2001:202:22:01:46 305.4 2001:202:21:20:02 0 437 1160 156 < 1 hr 2002:125:09:48:36 65.6 2002:104:17:17:02 31 0 327 860 21 2002:213:03:43:06 98.4 2002:178:04:50:08 0 326 860 473 35 2002:220:01:10:36 84.0 2002:178:04:50:08 0 326 860 473 42 2002:258:09:54:06 61.5 2002:254:00:15:02 0 60 568 680 4 2003:088:04:03:26 789.2 2003:015:16:36:29 2951 463 0 2525 73 2003:174:18:05:26 293.1 2003:163:13:26:32 867 0 783 1060 11 2004:123:23:40:36 69.7 2004:089:18:16:39 421 0 740 430 34 "Weak" events (strength < 50)Hi Bgd Time Strength Mom Dump Time A1 A2 A3 A4 Delta_T ----------------- ------ ----------------- ----- ------ ----- ----- ------- 2002:361:19:20:16 12.3 2002:356:12:30:03 2080 0 806 1022 5 2003:178:22:24:06 10.2 2003:163:13:26:32 867 0 783 1060 15 2003:190:19:36:56 18.4 2003:163:13:26:32 867 0 783 1060 27 2003:215:15:35:36 47.1 2003:203:15:04:17 236 0 584 1180 12 2004:013:07:10:56 16.4 2003:301:11:19:58 1380 484 0 893 27 2004:033:07:05:46 18.4 2003:301:11:19:58 1380 484 0 893 97 2004:104:12:39:26 22.5 2004:089:18:16:39 421 0 740 430 15 Aspect Information main page Comments or questions: Aspect Help Last modified:12/27/13 |
