Small flares with unusually strong X-ray emission Original Research Article

The RF15-I X-ray photometer aboard INTERBALL-Tail satellite has observed numerous flares of B GOES class with significant emission above 30 keV. In this paper we analyse these flares using Yohkoh SXT images and RF15-I data. We show that some of these flares occur in systems of relatively small low laying loop systems with Y type interaction.
