Coordinated observations of a large impulsive flare on UV Ceti.
Abstract
The characteristics of the major flare observed on UV Ceti on Decemmber 1985 at 01:26 UT during an international observing campaign are described. X-ray observations were obtained with Exosat in the 0.06-0.3 keV bands and 1-6 keV bands; optical photometry was obtained in 11 wavelength bands, and spectra were recorded in the wavelength range 3500 to 7000 A. The results of the data analysis support the Impulsive Explosion Model proposed for stellar flares and disclose some differences with the solar case.
