ИСТИНА

We present a catalogue of solar flare data observed with two Ondřejov optical spectrographs during 1998-2007 years. This database was created to enable the data processing more convenient for users interested in the study of the energy release and transport in solar flares. The spectra and Hα filtergrams were obtained both at the Multichannel Flare Spectrograph (MFS) and at the Large Horizontal Spectrograph (HSFA2). The catalogue contains basic information about time of observation of solar flares, their location in AR, importance, availability of related data at the selected Xray, EUV and radio instruments. The catalogue is available at www.asu.cas.cz/~sos/flare_archive.html .
