FLIGHT OPERATIONS SUMMARY:

Significant Spacecraft Anomalies: (The following are preliminary 
reports of potential non-nominal performance that will be 
investigated.)

HSTAR 8948: STIS Tungsten Lamp Failed to Turn On. On day 03/061 
             (03/02/03) at 19:57:06 UT, a target acquisition image was 
             taken with STIS's CCD. The third sub-exposure of that 
             image, that is a through-slit exposure of 0.1 sec in 
             length with the Tungsten lamp ON, did not show any flux 
             (other than background noise). Under investigation.

HSTAR 8950: GSacq(1,2,1) results to Finelock Backup (2,0,2). The 
             GSACQ(1,2,1) of 066/06:32:55 - 06:40:17 which begun 
             during ZOE, resulted to Finelock Backup, at AOS 
             066/06:49:04 using FGS#2 (2,0,2) due to SCANSTEP LMT EXC 
             on FGS#1.Possible observations affected:STIS 87,88 WFPCII 
             150 thru 160.  The guide star acquisition for this 
             observation was non-nominal, further analysis will 
             determine if a repeat observation is required.
