Report from ISAS 8 - 14 August 1994 Nariaki Nitta SUMMARY Compared with the previous week, the operations were less hectic even though a CCD bakeout was carried out. A rapidly growing region appeared well after the emerging flux observing campaign was over last week. Some serious scientific activities resumed. PERSONNEL No change in the US SXT operations team. The usual absence of people from Japanese institutions (such as NAOJ) was severer because of the big summer holiday period in Japan. OPERATIONS The bakeout was finished without operational problem. So far, there have not been as many dark images to look at as one can find out the effect of the bakeout. The typhoon season started at last. A major one (No. 14) attacked the Uchinoura/Kagoshima operations center, resulting in loss of data in a few visible orbits. SOLAR ACTIVITY The last target region of the Hida campaign, AR 7762, did not show remarkable growth after all. However, as Hugh Hudson heard from B.V. Jackson, it produced an IPS signature, whose identification would have been much harder had there been many other regions on the Sun. An apparently more energetic region, AR 7765, emerged rather abruptly on 12 August, producing many C class flares and finally an M4 flare at 17:35 UT on 14 August. This flare was well observed by Yohkoh and as intense as one could synthesize HXT maps in its highest energy channel. We will be on the alert for this region for some time. SCIENCE Mukul Kundu, a vising professor at ISAS until early September, and his collaborators, have come up with a nice result of comparing SXT and meter wave data. Type III bursts as observed at Nancay are shown to be correlated both spatially and temporally with at least two ``anemone jets'' of K.Shibata and his student M.Shimojo. This result, plus the U burst reported by Pick et al. in the Kofu proceedings, may clarify the geometry of fast-drift radio bursts near the Sun, with angular resolution far exceeding any available at metric wavelengths where such events are normally observed. These examples suggest that the electrons responsible for type IIIs propagate along the channels that are relatively narrow and sharply defined, not expanding strongly with height. They are accompanied by plasma ejection in the jet. K.Shibata, who is presently enjoying Texan life, will certrainly be interested in this result. Both Hugh Hudson and Nariaki Nitta are also working with Kundu finding X-ray signatures of type II, III and IV emissions from flares. ISAS WORKSTATIONS One of the workstations the SXT-U team brought to ISAS had kept causing problem. Gary Linford helped a DEC service person replace the sick disk. He also backed up all our workstations. In comparison, one cannot help wondering how often the J-side workstations are backed up. There are some 20 workstaions, which would be really nice if they were working properly. It is a pity five Sparc-10 workstations are sitting here, doing almost nothing for two months. The lack of IDL is not the only problem. Now there are too many disks, which would frequently undergo time-out if all of them were cross- mounted. Some local graduate students are assigned to be managers of these workstations, but considering their rare presence at ISAS, we may need a full- time specialist, getting this humongous system under control. SEMINAR There was no Yohkoh seminar this week or next. However, an extended seminar modelled on the Californian neighborhood meeting is planned for 24 August. Six or seven graduate students and young scientists have already told us enthusiastically that they want to speak at the seminar.
