Heavy Ion Counter (HIC) Galileo SS Derived Ion Fluxes Oct89 Solar Event readme.txt ============================================================================= Brief Bundle Description ============================================================================= This Bundle includes values for the fluxes of heavy ions associated with an energetic particle event of solar origin. The values are derived from HIC data taken during the Interplanetary Cruise to Jupiter. All data files are stored in the 'DATA' branch of the directory tree. Most data are stored in ASCII tables although some binary data may also be included. All files give time values in Spacecraft Event Time (SCET). Some files may give an additional time column that contains the Earth Received Time (ERT) in addition to the SCET. Users of these data are encouraged to acknowledge both the PDS and the principal investigators of the instruments whose data is used in analysis in all publications. ============================================================================= Mission Facts ============================================================================= The Galileo spacecraft and some science instruments were reprogrammed after arrival at Jupiter so that data acquisition and downlink could be achieved at the low bit rates associated with the mission after the high gain antenna (HGA) anomaly (see readme_oct89flare-ionfluxes.txt file in the Document directory). New software was telemetered to the spacecraft in early May 1996 in a period known as the 'Inflight Load' or IFL. The mission prior to the IFL is known as the Phase 1 mission. After the IFL the mission is referred to as the Phase 2 mission. In Phase 1 raw data were provided to the instrument teams in Experiment Data Record (EDR) format. In Phase 2, the whole telemetry stream and ground data system were changed. The raw data were 'packetized' and delivered electronically as packet files or instrument packet files (IPF). The difference between a packet file and an IPF is a single 44 byte header called an SFDU. The Io data stored on this Bundle were acquired during Phase 1 and downlinked after the IFL by use of the new capabilities of the Phase 2 flight software. As such, they are a hybrid form of data that were acquired by using flight software that may differ from other files of the same raw data format. This is primarily of concern when instrument reprogramming has resulted in a change in the contents of the raw data (i.e. MAG). The Galileo orbits were named by concatenating the first letter of the name of the primary target in each orbit with the orbit number. Thus, the fourth Jupiter orbit, in which Europa is the primary target, is called E4. The project defined orbits according to spacecraft command load boundaries rather than the normal convention of apoapsis to apoapsis. The navigation team did not always adhere to this convention, causing some confusion. The PDS has organized the data and data delivery schedules around the project defined orbit boundaries. The following tables contain information about the orbital tour and satellite encounters: --------------------------------------------------------------------- Galileo Orbit Information --------------------------------------------------------------------- Orbit Orbit <--- Periapsis Info ----> <-- Apoapsis Info --> Num Start Periapsis Range Local Apoapsis Range Local Date Date/Time Time Date Time --------------------------------------------------------------------- J0 95-12-03 95-12-07 21:54 4.00 16:21 96-03-29 267.7 03:39 G1 96-06-23 96-06-28 00:31 11.03 15:36 96-08-09 125.3 03:24 G2 96-09-01 96-09-07 13:38 10.65 15:22 96-10-07 113.0 03:12 C3 96-11-02 96-11-06 13:31 9.21 15:34 96-11-27 89.1 03:28 E4 96-12-15 96-12-19 03:22 9.16 15:21 97-01-04 72.1 03:00 J5* 97-01-15 97-01-20 00:26 9.05 14:54 97-02-04 72.1 02:48 E6 97-02-16 97-02-20 20:55 9.12 14:28 97-03-14 89.2 02:20 G7 97-03-30 97-04-04 11:03 9.12 14:14 97-04-21 75.9 01:56 G8 97-05-04 97-05-08 11:42 9.27 13:29 97-06-02 100.2 01:21 C9 97-06-22 97-06-27 11:52 10.77 12:35 97-08-08 143.0 00:21 C10 97-09-14 97-09-18 23:10 9.17 12:44 97-10-13 98.9 00:36 E11 97-11-02 97-11-06 23:02 9.03 12:36 97-11-26 84.1 00:29 E12 97-12-15 97-12-16 06:35 8.80 12:29 97-12-20 46.6 00:37 J13* 98-02-09 98-02-10 23:09 8.85 12:33 98-03-06 95.2 00:25 E14 98-03-28 98-03-29 07:59 8.83 12:17 98-04-30 199.7 00:16 E15 98-05-30 98-06-01 02:34 8.85 12:12 98-06-26 100.4 00:03 E16 98-07-20 98-07-20 17:18 9.93 11:54 98-08-23 124.4 23:51 E17 98-09-25 98-09-26 08:26 8.91 11:44 98-10-24 110.4 23:34 E18 98-11-21 98-11-22 03:57 9.23 11:24 98-12-27 129.0 23:17 E19 99-01-31 99-02-01 02:38 9.24 10:56 99-03-18 154.3 22:40 C20 99-05-02 99-05-03 17:00 9.37 10:24 99-06-02 114.5 21:46 C21 99-06-29 99-07-02 05:04 7.27 10:04 99-07-22 89.0 21:57 C22 99-08-11 99-08-12 10:58 7.32 09:50 99-08-29 77.1 21:23 C23 99-09-13 99-09-14 19:57 6.55 09:17 99-09-27 65.7 20:46 I24 99-10-10 99-10-11 03:31 5.68 08:41 99-11-01 97.7 20:47 I25 99-11-25 99-11-26 23:30 5.94 08:39 99-12-15 87.2 20:28 E26 00-01-01 00-01-04 03:33 5.78 08:14 00-01-28 102.7 20:05 I27 00-02-20 00-02-22 12:30 5.85 07:56 00-04-06 154.4 19:55 G28 00-05-17 00-05-21 04:52 6.68 07:18 00-09-08 289.9 18:37 G29 00-12-27 00-12-29 03:26 7.49 06:03 01-03-11 216.3 17:37 C30 01-05-07 01-05-23 17:33 7.28 05:11 01-06-29 136.8 16:27 I31 01-08-04 01-08-06 04:52 5.93 04:14 01-09-10 132.2 16:05 I32 01-10-14 01-10-15 23:56 5.78 03:53 01-12-01 160.7 15:39 I33 02-01-16 02-01-17 16:23 5.54 03:13 02-06-13 348.1 14:21 A34 02-11-04 02-11-05 07:23 1.99 01:40 03-04-14 336.7 12:49 J35 03-09-21 03-09-21 18: 1.00 * Solar Conjunction - no data from this orbit ** Rj = 71492 km ------------------------------------------------------------ Satellite Flyby Characteristics* ------------------------------------------------------------ Satellite Planetocentric Coords Range Lat E Lon Orb Moon C/A Time (Rm**) (deg) (deg) Note ------------------------------------------------------------ 0 IO 95-12-07 17:45:58 1.50 -9.6 258.9 W 24 IO 99-10-11 04:33:03 1.34 4.5 135.9 U 27 IO 00-02-22 13:46:41 1.11 18.5 157.4 U 31 IO 01-08-06 04:59:21 1.11 77.5 187.7 P 32 IO 01-10-16 01:23:21 1.10 -78.5 135.3 P 33 IO 02-01-17 14:08:28 1.06 -43.5 41.8 F 4 EUR 96-12-19 06:52:58 1.45 -1.7 322.4 F 6 EUR 97-02-20 17:06:10 1.38 -17.0 34.7 F 11 EUR 97-11-06 20:31:44 2.31 25.7 218.7 F 12 EUR 97-12-16 12:03:20 1.13 -8.7 134.4 U 14 EUR 98-03-29 13:21:05 2.06 12.2 131.2 U 15 EUR 98-05-31 21:12:57 2.62 15.0 225.4 W 19 EUR 99-02-01 02:19:50 1.93 30.5 28.1 U 26 EUR 00-01-03 17:59:43 1.22 -47.1 83.4 U 1 GAN 96-06-27 06:29:07 1.32 30.4 246.7 W 2 GAN 96-09-06 18:59:34 1.10 79.3 236.4 P 7 GAN 97-04-05 07:09:58 2.18 55.8 270.4 W 8 GAN 97-05-07 15:56:10 1.61 28.3 84.8 U 28 GAN 00-05-20 10:10:10 1.31 -19.0 92.4 U 29 GAN 00-12-28 08:25:27 1.89 62.2 269.0 P 3 CALL 96-11-04 13:34:28 1.47 13.2 282.3 W 9 CALL 97-06-25 13:47:50 1.17 2.0 101.0 U 10 CALL 97-09-17 00:18:55 1.22 4.6 281.3 W 30 CALL 01-05-25 11:23:58 1.06 13.6 254.6 W 34 AMA 02-11-05 06:18:40 2.89 -47.7 74.8 U * Satellite encounters with recorded data only J2000 reference, body fixed spherical coordinates. ** Moon Rm (km) ======================= Amalthea 86.2 Io 1818 Europa 1560 Ganymede 2634 Callisto 2409 Notes: Negative latitudes are southern hemisphere, U = upstream F = flank W = wake P = polar =========================================================================== Contacts =========================================================================== The person most directly responsible for the construction and release of this Bundle is Mr. Steven Joy.
