22 July 1995 D. Alexander SXT CHIEF OBSERVER REPORT AND TABLE PLAN SXT TABLE PLAN FOR WEEK 30 (24-JUL-95 to 30-JUL-95) This week we will only carry out standard ARS1 observing since Hawaii are still waiting for the MCCD to be repaired. We will continue to take offpoint terminator images with the new OG in preparation for the Spartan observations. The observing objectives of this plan are: - Dark Calibration on Monday. - Take offpoint terminator images. The SXT Table Plan for the week is as follows. PLEASE REMEMBER THAT THIS IS SUBJECT TO CHANGE. Our default mode is ARS1 STD+LONG. An asterisk (*) means that the table will only be necessary if there is a change in the terminator filter.

The SSOC tohbans are required to manually insert the off-point OGs for the terminators in the OP tables. The SSOC tohbans, please fax the preliminary OP list to D-tou when it contains a terminator so that the Chief Observer can suggest which OG's to be used. Dumping Patrol images: We request that KSC tobans continue to dump a patrol image each time an SXT table is loaded to facilitate the study of optimizing ARS parameters for an awfully quiet period. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ SXT CHIEF OBSERVER'S REPORT for Week 29: 17-JUL-95 to 23-JUL-95 Sun very quiet again this week. Main operations this week were quiet corona studies on Wednesday and Thursday. Filament campaign is on hold. SOLAR ACTIVITY There is not much to report in terms of activity at the moment. There were a couple of small active regions showing some nice loops. SXT INSTRUMENT STATUS The SXT has been operating without any problem. FILAMENT OBSERVATIONS This ongoing campaign was again on hold this week since filament activity was not too exciting and also due to a hardware problem at Mees. UPCOMING CAMPAIGN Spartan 201-03 is scheduled for a ***NEW*** launch date on 5 August, followed by deployment 24.5 hours later. It will observe solar corona for 43.5 hours. I reminded the UV team of the availability of SXT daily images at CRL, but we will be contacted for more coordination. Our observing plan is still as follows: Observations of the Sun one rotation before the Spartan flight show a large streamer off the SE limb which should provide an excellent target for Spartan. Current plans for SXT are to offpoint to target this region and to minimise pinhole straylight effects. AR7887 was close to the west limb on July 10 and showed some large loop structures. This may prove to be a viable target for Spartan one rotation from now but is unlikely. We will monitor the activity nearer launch and report to the Spartan observers. We will not do anything special for the Northern Coronal Hole observations. Hudson-san created a new OG for the planned offpoint. We will use this for the offpoint terminators from now until after the Spartan flight. The KSC contacts are shown for the Spartan flight are shown on the next page.
