• No Changes since last meeting
• ISA Z70771
– Fixed by FSW patch in C24
– Fixed by FSW V1.3 starting C31
• ISA Z86939 (bad EUV data in S11 icylon)
– Probably FSW problem
– Workaround by updating the instrument setup

UVIS_020IC_IMPACT002_RIDER,
UVIS_020IC_IMPACT003_RIDER and
UVIS_021IC_IMPACT002_RIDER: Overflow of the internal buffer - HSP is OK, FUV was not ingested.

HSP field of view.
• Checklist updated
– All IPHSURVEYs in S20 assumed a non-rotating S/C.

• New trajectory/deletion of IMPACT requests
– Example S25
• 14 prime requests - 11 to be re-done (partially or completely)
• Shorter sequence (30 days vs 45 days)
• S23/S24/S25 DSN allocation issues
• As much as possible before the start of a sequence development go thru all the requests and check the instrument setup - S23 has been really bad.
• And when defining an instrument setup use the instrument set up language that was defined in
2001.

• The accuracy of the SCLK to SCET conversion depends on which version of convert_sclk.pro is used.
• Currently you should be running version 1.12
(which follows the latest version of the spacecraft clock conversion file - SCLKSCET.00098)
• The convert_sclk.pro version number is at the top of the file
