===========================================================

DATA LOSSES:

1846-1849: Realtime data lost due to stn CPA problem
0400-0501: Several momentary dropouts


PASS ACTIVITIES SUMMARY:

PASS 1. SSR DUMP
SUPPORT TIMES:  0840-1336      STATION: D66

Nominal SSR dump.  S/C nominal.


PASS 2. SSR DUMP, Experiment Power-ON (SWAN, CEPAC, LASCO/EIT), Guide Star 
Update/CCD Test
SUPPORT TIMES:  1545-2331      STATION: D16

Nominal.  SWAN powered ON.  NRT: 1633-44.  CEPAC powered ON.  Set ESR Warning

flag for experiments:  UVCS, CEPAC, SWAN, and MDI.  Performed OCD 48: MDI 
Oven Thermal control Monitoring.  Performed guide star change to Mv 3 double 
star and released all others for CCD background level checkout.  LASCO/EIT 
powered ON.  Loaded 7-day HGA Nominal Control table good until 14 Dec/2000.  
Performed additional manual OBT correlations.  Delta appears to be fairly 
steady at approximately 38-39 msec. fast.  Handover to D42 at 2249.


PASS 3. SSR DUMP, LASCO Power Recycle
SUPPORT TIMES:  2255-0735      STATION: D42

Nominal S/C.  SSR dump nominal.  Some problems at station with uplink.  TRSP2

lost lock several times.  D42 requested expanding their tracking bandwidth 
from 1200 to 4800 Hz.  DR opened.  LASCO processor hung.  Ran OCD 52 to cycle

LASCO LEB power at 0430 - successful.  NRT up at 0455.  Lost D/L at site at 
0501 briefly - expect same problem as before.  Continued LASCO NRT.  LASCO 
requested OBT dist. - executed at 0549.  SSR->record @ 0719.  Stn S/S=-107dB.


PASS 4. SSR DUMP
SUPPORT TIMES:  0840-1336      STATION: D66

Nominal SSR dump.  S/C nominal.
