http://earthobservatory.nasa.gov/cgi-bin/MissionControl/overpass.pl 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 /bin/sh -c "/WWW/site-bin/SatTrack/run/sattrack -b '2' 'LatLong+51.971-4.927' 28376 tlex.dat norad shortpr 03Jun05 0:0:0 auto 14 40 nohardcopy" Satellite #28376 : AURA Element Set Number: 222 (Orbit 3372) Element Set Epoch : 03Mar05 22:10:15.546 UTC (3.6 days ago) Orbit Geometry : 698.82 km x 700.41 km at 98.196 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 Sun 08May05 14:11:53 14:18:44 14:25:51 153 72 348 63.1* 687 DDD 4329 Mon 09May05 13:17:49 13:24:08 13:30:28 125 59 354 24.2 686 DDD 4343 14:54:32 15:01:31 15:08:38 175 259 343 57.9* 688 DDD 4344 Tue 10May05 13:59:41 14:06:32 14:13:31 147 68 349 50.0* 687 DDD 4358 15:37:59 15:44:34 15:51:09 198 268 337 25.6 688 DDD 4359 Wed 11May05 14:42:12 14:49:11 14:56:18 169 251 345 73.6* 688 DDD 4373 Thu 12May05 13:47:36 13:54:20 14:01:11 141 66 351 40.0* 687 DDD 4387 15:25:31 15:32:06 15:38:57 191 263 339 32.1 689 DDD 4388 Fri 13May05 14:30:00 14:36:59 14:44:06 163 44 346 88.0* 688 DDD 4402 Sat 14May05 13:35:32 13:42:08 13:48:51 135 64 352 32.4 687 DDD 4416 15:13:03 15:19:46 15:26:45 185 261 341 40.4* 688 DDD 4417 Sun 15May05 14:17:48 14:24:39 14:31:46 156 77 347 70.7* 688 DDD 4431 Mon 16May05 13:23:36 13:29:55 13:36:31 128 62 353 26.6 686 DDD 4445 15:00:35 15:07:26 15:14:33 178 257 342 51.3* 688 DDD 4446 Tue 17May05 14:05:36 14:12:27 14:19:26 150 70 349 56.0* 687 DDD 4460 Wed 18May05 14:48:15 14:55:14 15:02:13 172 261 344 65.5* 688 DDD 4475 Thu 19May05 13:53:23 14:00:15 14:07:06 144 67 350 44.5* 687 DDD 4489 15:31:33 15:38:09 15:44:52 194 266 338 28.7 688 DDD 4490 Fri 20May05 14:35:52 14:42:51 14:49:58 166 240 345 82.5* 688 DDD 4504 Sat 21May05 13:41:24 13:47:59 13:54:51 138 66 351 35.9 687 DDD 4518 15:19:03 15:25:46 15:32:37 188 262 340 36.0 688 DDD 4519 Sun 22May05 14:23:40 14:30:39 14:37:46 159 71 347 79.1* 688 DDD 4533 Mon 23May05 13:29:20 13:35:55 13:42:30 132 61 352 29.3 686 DDD 4547 15:06:35 15:13:26 15:20:25 181 260 342 45.6* 688 DDD 4548 Tue 24May05 14:11:27 14:18:26 14:25:25 153 66 348 62.7* 687 DDD 4562 Wed 25May05 13:17:24 13:23:43 13:30:10 125 59 354 24.1 686 DDD 4576 14:54:15 15:01:06 15:08:13 175 256 343 58.1* 688 DDD 4577 Thu 26May05 13:59:15 14:06:06 14:13:05 147 70 349 49.7* 687 DDD 4591 15:37:41 15:44:09 15:50:44 198 267 337 25.8 688 DDD 4592 Fri 27May05 14:41:54 14:48:54 14:55:53 169 264 345 73.9* 688 DDD 4606 Sat 28May05 13:47:11 13:53:54 14:00:45 141 67 351 39.8 687 DDD 4620 15:25:05 15:31:49 15:38:32 191 266 339 32.2 688 DDD 4621 Sun 29May05 14:29:34 14:36:33 14:43:40 162 65 346 87.8* 687 DDD 4635 Note- OMI spatial zoom mode!
