http://earthobservatory.nasa.gov/MissionControl/overpass.html Output format descriptions for Predicted Overpass Summaries Overpass predictions are presented as one line per overpass in this format, with the following information provided: Date The date of the predicted passes Time of Rise/Peak/Set The time for each pass's start, maximum (peak) elevation, and end. Azimuth at Ris/Pk/Set The azimuth (direction the observer must face) to the spacecraft, in degrees, when the pass begins, when the spacecraft reaches maximum elevation, and when the pass ends. 0 corresponds to north, 90 east, 180 south, and 270 west. Peak Elev The spacecraft's maximum elevation above the horizon, in degrees, for this pass. This will be at the time and azimuth specified in the previous columns. Passes with a peak elevation of 40.0 degrees or more are marked with an asterisk (*) at the end of this field. Height at Pk The spacecraft's altitude above the ground in kilometers at the time of peak elevation. Note that this is NOT the distance from the spacecraft to the observer. Vis A three-letter indicator of the spacecraft's visibility at the beginning of the pass (spacecraft rise), maximum elevation, and at the end of the pass (spacecraft set). The letters used are: N spacecraft is in the night portion of the orbit D spacecraft is in the day portion of the orbit V spacecraft is in the day portion of the orbit and the ground site is in nautical twighlight (sun at least 6 degrees below the horizon), making the spacecraft visible Orbit The spacecraft's orbit number for this pass, counting from launch Satellite #28376 : AURA Element Set Number: 642 (Orbit 10461) Element Set Epoch : 03Jul06 17:22:05.845 UTC (1.7 days ago) Orbit Geometry : 698.86 km x 700.57 km at 98.245 deg Propagation Model : SGP4 Ground Location : Lat/Long 51.971000N 4.927000E (Cabauw) Time is shown in : LOC (+2.00 h) * Note - repeat cycle Aura is 16 days (not perfect) * Local clock time including Daylight Savings (= UT + 2) OVERPASS SUMMARY: Date (LOC) Time (LOC) of Azimuth at Peak Height Vis Orbit Rise Peak Set Ris Pk Set Elev at Pk Fri 01Sep06 13:22:29 13:28:49 13:35:16 126 60 354 24.6 686 DDD 11333 14:59:20 15:06:19 15:13:18 176 261 343 56.7* 688 DDD 11334 Sat 02Sep06 14:04:30 14:11:22 14:18:21 148 67 349 51.0* 687 DDD 11348 15:42:49 15:49:24 15:55:59 198 268 337 25.2 689 DDD 11349 Sun 03Sep06 14:47:04 14:54:03 15:01:10 169 252 344 72.1* 688 DDD 11363 Mon 04Sep06 13:52:30 13:59:13 14:06:04 141 67 350 40.8* 687 DDD 11377 15:30:24 15:37:07 15:43:51 192 266 339 31.5 689 DDD 11378 Tue 05Sep06 14:34:55 14:41:54 14:49:01 163 164 346 89.3* 688 DDD 11392 Wed 06Sep06 13:40:29 13:47:12 13:53:56 135 62 351 33.1 687 DDD 11406 15:18:00 15:24:51 15:31:50 185 263 341 39.5 689 DDD 11407 Thu 07Sep06 14:22:46 14:29:45 14:36:52 157 73 347 72.3* 688 DDD 11421 Fri 08Sep06 13:28:36 13:35:04 13:41:39 129 62 353 27.1 687 DDD 11435 15:05:43 15:12:34 15:19:41 179 258 342 50.1* 689 DDD 11436 Sat 09Sep06 14:10:46 14:17:37 14:24:36 151 71 349 57.3* 688 DDD 11450 15:49:20 15:55:47 16:02:14 202 269 336 22.5 689 DDD 11451 Sun 10Sep06 13:16:51 13:23:03 13:29:23 123 59 354 22.4 686 DDD 11464 14:53:27 15:00:26 15:07:33 172 258 344 63.9* 688 DDD 11465 Mon 11Sep06 13:58:45 14:05:28 14:12:27 145 69 350 45.6* 687 DDD 11479 15:36:55 15:43:31 15:50:14 195 267 338 28.1 689 DDD 11480 Tue 12Sep06 14:41:18 14:48:17 14:55:24 166 265 345 80.6* 688 DDD 11494 Wed 13Sep06 13:46:44 13:53:28 14:00:11 138 64 351 36.8 687 DDD 11508 15:24:31 15:31:14 15:38:05 189 264 340 35.1 689 DDD 11509 Thu 14Sep06 14:29:10 14:36:09 14:43:08 160 60 346 80.9* 688 DDD 11523 Fri 15Sep06 13:34:52 13:41:20 13:48:03 132 63 352 30.0 687 DDD 11537 15:12:07 15:18:58 15:25:57 182 261 341 44.4* 689 DDD 11538 Sat 16Sep06 14:17:02 14:24:01 14:31:00 154 66 348 64.5* 688 DDD 11552 15:55:51 16:02:11 16:08:30 205 271 335 20.1 689 DDD 11553 Sun 17Sep06 13:22:59 13:29:19 13:35:46 126 60 353 24.7 686 DDD 11566 14:59:51 15:06:50 15:13:49 176 262 343 56.4* 688 DDD 11567 Mon 18Sep06 14:05:01 14:11:52 14:18:51 148 66 349 51.2* 687 DDD 11581 15:43:19 15:49:46 15:56:30 198 266 337 25.1 689 DDD 11582 Tue 19Sep06 14:47:34 14:54:33 15:01:40 169 254 344 71.8* 688 DDD 11596 Wed 20Sep06 13:53:00 13:59:43 14:06:35 141 66 350 41.0* 687 DDD 11610 15:30:55 15:37:38 15:44:21 192 266 339 31.3 688 DDD 11611 Thu 21Sep06 14:35:25 14:42:24 14:49:31 163 270 346 89.6* 688 DDD 11625 Fri 22Sep06 13:41:00 13:47:35 13:54:18 135 65 352 33.2 687 DDD 11639 15:18:30 15:25:21 15:32:12 185 263 340 39.3 688 DDD 11640 Sat 23Sep06 14:23:17 14:30:16 14:37:23 157 71 347 72.7* 688 DDD 11654 Sun 24Sep06 13:29:07 13:35:34 13:42:09 129 61 353 27.2 686 DDD 11668 15:06:14 15:13:05 15:20:04 179 259 342 49.9* 688 DDD 11669 Mon 25Sep06 14:11:16 14:18:07 14:25:06 151 70 348 57.6* 687 DDD 11683 15:49:50 15:56:10 16:02:45 202 267 336 22.4 689 DDD 11684 Tue 26Sep06 13:17:14 13:23:34 13:29:53 123 58 354 22.5 686 DDD 11697 14:53:57 15:00:56 15:07:55 173 260 344 63.6* 688 DDD 11698 Wed 27Sep06 13:59:15 14:05:59 14:12:58 145 68 350 45.8* 687 DDD 11712 15:37:26 15:43:53 15:50:36 195 265 338 27.9 688 DDD 11713 Thu 28Sep06 14:41:41 14:48:40 14:55:47 166 242 345 80.1* 688 DDD 11727 Fri 29Sep06 13:47:15 13:53:59 14:00:42 138 63 351 36.9 686 DDD 11741 15:24:54 15:31:45 15:38:36 188 266 340 35.0 688 DDD 11742 Sat 30Sep06 14:29:33 14:36:32 14:43:39 160 82 346 81.4* 687 DDD 11756
