These measurements, occultations 15538i through 15540i (start times 2002/242- 01:42:00 through 2002/242-05:38:00), have +/-0.3 dB random fluctuations in the free-space carrier amplitude due to solar plasma effects. With the exception of DOY 242 and two possible occultations on DOY 245 described immediately below, all measurements included in this report have random free-space carrier amplitude fluctuations due to solar plasma of less than +/-0.2 dB. Fluctuations are now low enough that levels can be considered normal, and there will be no explicit mention of random fluctuations in the carrier amplitude with magnitude less than +/-0.2 dB in future reports. Data collected from DSS 15 (occultation 15574i, start time 2002/245- 00:20:00) had +/-0.4 dB random fluctuations in free-space carrier amplitude over the 30 seconds before ingress. The second measurement captured by DSS 45 on DOY 245, occultation 15586i (start time 2002/245-23:52:00), had +/-0.5 dB random fluctuations in the free-space carrier amplitude. Two out of six scheduled measurements in a pass from DSS 15 were lost to scripting errors (occultations 15569i and 15570i, start times 2002/244- 14:31:00 and 16:29:00, respectively). The remaining four measurements were successfully captured. The first DSS 45 measurement on DOY 245 (occultation 15575i, start time 2002/245-02:17:00) had +/-0.4 dB sinusoidal modulation of the carrier amplitude with period of about 45 seconds before telemetry turned off. It lasted about 3 minutes into the measurement before damping out to normal levels about two minutes before ingress. The second DSS 45 measurement on DOY 245 (occultation 15576i, start time 2002/245-04:15:00) had a small +0.5 dB ramp in the noise level after ingress. The third DSS 45 measurement on DOY 245 (occultation 15577i, start time 2002/245-06:13:00) had a +1 dB ramp in the carrier amplitude over the entire measurement, including both before telemetry turned off and after ingress. This measurement was also successfully captured at DSS 65. Data collected from DSS 65, occultation 15577i (start time 2002/245-06:13:00), had a -0.5 dB ramp in the noise level after ingress. Both DSS 54 measurements (occultations 15579i and 15580i, start times 2002/245-10:08:00 and 12:06:00, respectively) had -0.5 dB dips in the free-space carrier amplitude. For occultation 15579i, there were two -0.5 dB dips over 20 seconds, the first occurring about 80 seconds after telemetry turned off, and the second ended about 80 seconds before ingress. For occulation 15580i, there was one -0.5 dB dip over about 80 seconds, ending about 120 seconds before ingress. There was a small +1 dB spike over about 5 seconds in the noise level for occultation 15585i (start time 2002/245-21:54:00), the first measurement in a pass from DSS 45. The following occulatations had noise level changes after ingress: Occultation Start Date/Time DSS Level Change Time ----------- ----------------- --- ------------ -------- 15568i 2002/244-12:33:00 65 +1 dB step ~150 s The following occultations were captured at two different antennas: Occultation Start Date/Time DSS #1 DSS #2 ----------- ----------------- ------ ------ 15577i 2002/245-06:13:00 45 65 15579i 2002/245-10:08:00 65 54 Closed Loop Data ================ Data Collection --------------- We have obtained the following files from OSCAR and EPIC: Original File Name Name on SOPC ------------------------------------ ------------ ODF: 02242O243_10S.SJO;1 2242243A.ODF ODF: 02243O245_10S.SJO;1 2243245A.ODF ODF: 02245O246_10S.SJO;1 2245246A.ODF TROPCAL: ATC02AUG.CSP;10 2213244B.TRO WEATHER: WEATHER_10_LATEST.TXT;336 20012461.WEA WEATHER: WEATHER_40_LATEST.TXT;336 20012464.WEA WEATHER: WEATHER_60_LATEST.TXT;336 20012466.WEA EOP: 020903-eop.long 20202329.EOP EOP: 020903-eop.short 13282329.EOP Ancillary Data ============== Data Collection --------------- We have obtained the following files from the DOM: Original File Name Name on SOPC ------------------------------------ ------------ AMD: amdgen.02-246.out 2245245A.AMD DKF: mm209a.01.dkf 2254257A.DKF DKF: mm210a.01.dkf 2258262A.DKF SAK: mgs_solar_array_2002-245.ck 2245245A.SAK SOE: mm209a.01.tsoe 2254258A.SOE SOE: mm210a.01.tsoe 2258262A.SOE TCK: mgs_spice_c_kernel_2002-245.ck 2245245A.TCK TCK: mgs_sc_ext5.bc 1346064A.TCK TCK: mgs_sc_ext6.bc 2065148A.TCK We have obtained the following files from NAIF and/or IPNG: Original File Name Name on SOPC ------------------------------------ ------------ AGK: mgs_hga_ck_2002-08-25.ck 2237237A.AGK AGK: mgs_hga_ext5.bc 2065148A.AGK
