Yohkoh Galileo meeting J. Sato The Goal of the Flare Catalogue 1: Sufficient information for flare analysis 2: Easy access to the Catalogue Direct and indirect usage for scientific paper product ◎
2
Instruments for the Catalogue SXT: Images HXT: Images, Timeprofiles, Spectrum WBS SXS: Timeprofiles and Spectrum(X) HXS: Timeprofiles and Spectrum GRS: Timeprofiles and Spectrum BCS:?? Supplements: Goes and NOAA number.. etc

Current Flare Catalogue Yohkoh Flare Image Catalogue (flare list and images) It covers from 1991/10 to 2001/12. http://www.solar.physics.montana.edu/sato/ We achieved 1: HXT Flare list 2: SXT and HXT images as a PNG File 3: FITS data of the HXT image near the peak time 4: Simplified documentation

Current Flare Catalogue
5
Future plan, I think at this point A1: Data correction of HXT 1: Correction of HXT PC and PH data (TBD) 2: flare images in some saturated flares 3 : BGD database (fits format) 4: Re-calibration of the HXT H-band modulation parameters (TBD) A2: Other instrumental data in the catalogue 5: Timeprofile and Spectrum derived from SXS, HXS and GRS 6: Gamma-line flare information from GRS 7: Plasma temperature derived from GOES data
6
Important future plan, I think…. B: Flare images 1: SXT Te, EM map near the peak time 2: HXT Spectral map near the peak time 3: beginning and decay flare images 4: Providing image data as a fits file 5: Flare movies and HXT movies (TBD)
