Multi-frequency observations of the February 6, 1992 flare
Observations of the two-ribbon flare of February 6, 1992 which occured in the active region NOAA 7042 involving a sigmoidal soft X-ray loop pattern, are described. YOHKOH SXT images, H-alpha filtergrams and coronal magnetic field extrapolations are used to reveal details of the preflare coronal magnetic field configuration. The development of the flare in SXR, H-alpha and dm-m radio wavelength range is followed in detail to disclose the basic stages of the energy release process.
