SXT REPORT FROM ISAS 27 May 94 to 21 June 94 J. R. Lemen, H. S. Hudson With the recent spate of traveling by several members of the SXT team to various meetings, it has been difficult to produce an SXT report from ISAS. This report been mostly written by HSH with some last minute inputs from JRL. SOLAR ACTIVITY Solar activity ranged from very low to just low as the "active" hemisphere rotated back onto the disk. Before its arrival one could note well-developed trans-equatorial interconnecting loops extending well outside the SXT field of view. These fluctuated slowly, as usual, and eventually were found to connect active regions NOAA 7730 (about S10) and NOAA 7731 (about N08 and half a day behind). This activity produced a background level of about B1 but no flares much larger than C1. PEOPLE David Alexander returned to Montana after an extremely productive tour as SXT chief observer. Marilyn Bruner and Greg Slater departed; Jim Lemen and Tom Metcalf arrived for month-long visits; visitors included Len Culhane, Todd Hoeksema, Mukul Kundu, Lidia van Driel, and N. Gopalswamy and Bernie Jackson. Many regulars (Harra, Hudson, Sterling) returned from the SPD and other activities at the beginning of the month. Brian Handy, a graduate student at MSU, arrived to begin a two-month visit. He will be training to become an SXT Chief Observer. CAMPAIGN ACTIVITIES A campaign organized by H. Kurokawa (Hida Observatory) proceeded until the middle of last week. This effort is aimed at rapid response to newly emerging flux based upon H-alpha guidance to arch filament systems. In between the rainy season in Japan and the low solar activity, some success has been achieved. Hida is now better connected by e-mail, which greatly facilitates observational programs of this type. A campaign effort coordinated by Karen Harvey was set up and began last week and is continuing this week. Its objective is to determine the spatial and temporal correspondence between XBPs and He I 10830 dark points. RESEARCH ITEMS LaBonte finished some interesting work on the terminator images which are used to correct for stray light. He was motivated partly in this area by looking at the long exposures in the S offpoints that Acton had been doing in his most recent visit. These show low-level phenomena in coronal holes (the S hole is well developed these days). Many people (Acton, Culhane, Hara, Hudson, Lemen, Uchida, et al) are interested in this work, which appears to be adding more mysteries to Hara-san's finding of high temperatures in coronal holes on the disk (cf. the 1993 November eclipse). One striking and simple observational result is the non-detection of limb brightening in coronal holes, something as yet unexplained Much discussion of the Masuda "home run" event echoes around D-toh. Shibata- san found ejecta in all of the Masuda events, by diligent examination of the low-resolution SXT flare data, and presented this result at the ASJ meeting. Similarly much discussion centers on the polar crown transient events, stimulated by the remarkable April 14, 1994 event that caused a CME resulting in damage to the terrestrial power grid. These flare-like events have become much more prominent in the past year, although the SXT prototype occurred in the N polar region as early as November 1991. The April event was interesting in that it appeared to point directly at Ulysses. M. Neugebauer brought Ulysses data for the relevant time to the IACG meeting in Sagamihara, however, and it was clear that no major effect took place. This is interesting from the point of view of our future ability to reconstruct the global connectivity of the 3-D coronal field configuration.
