SXT STATUS REPORT FROM ISAS Tuesday, 11 August 1992 Yohkoh operations for SXT and the spacecraft as whole have gone smoothly for the past few weeks. At the beginning of this week the SXT suffered a SEU in the portion of the micro-code that normally performs the SEU recovery. Thus, the micro could not recovery by itself, and a manual recovery was performed during the KSC real-time passes. Apart from this short interruption, data from SXT has been nearly continuous for the past month. The solar activity continues to be diminished as observed in SXT full-Sun images. Typically there are only one or two bright regions observed at any time. In the past couple of weeks only a few C flares and one M flare have been observed by Yohkoh. On 30 July a large prominence was observed to lift off the north-east limb by H-alpha telescopes at Mitaka. An arcade of loops was observed in the SXT images on the 31st near the same location. The X-ray images are typical of a region which has been restructured by a filament eruption or disapperance. More SXT images may become available when the DSN data has been reformatted for this time period. Unfortunately, our DSN coverage has been reduced by about a factor 4 to 5 from what we normally expect because of the Space Shuttle operations. Special coordinated observations with the VLA as a part of the Max 91/Flares 22 program were conducted on different days over the past three weeks. This campaign will resume later in August on three different occasions. This campaign is emphasizing flare observations. The Lockheed Tunable Filter has been observing from the Swedish Observatory in La Palma (1 May - 3 July) and more recently from the German Vacuum Tower in Tenerife. On 3 July a flare was well observed by both the SXT and the Tunable Filter. This data set may very well represent the best joint X-ray/visible observations of a flare every obtained. The analysis of this data is currently underway. The Tunable Filter follows the same region as the SXT for a portion of each observing day. These observations are expected to continue from Tenerife until some time in September. -- End of Report: J. R. Lemen --
