Solar white-light flare in AR6659☆
Review articleOpen access

AbstractA solar white-light flare (WLF) was observed at the Beijing Astronomical Observatory in the AR6659 on June 6, 1991. The white light emission was accompanied by intense Hα X-ray and microwave emissions. We studied this event and estimated the total power emitted by the WLF knots in the wavelength band of the observation (between 3590Å — 3610Å) to be P = 4.96 × 1025erg.s−1. The energy of the WLF on 3600 Åis estimated to be E(3600 Å)= 7.54 × 1028erg. The estimated energy of WLF in the whole optical wavelength range (3590 Å-6391 Å) is E = 1.21 × 1031erg.
