摘要
1991年6月6日我们在太阳6659号活动区观测到了一个白光耀斑.这个白光耀斑伴有强烈的H_α、X射线和射电微波发射.我们对这次自光事件作了初步的分析研究,并对它的总能量作了粗略估计.
A solar white-light flare (WLF) was observed at the Beijing Astronomical Observatory in the AR6659 on 6 June, 1991. The white light emission is accompanied by intense Hα, X-ray, and microwave emissions. We studied this event and made an estimation for the total power emitted by the WLF knots in the Wavelength interval of the observation (between 3590A-3610A) to be P =4.96 × 1025 erg · sec-1. The energy of the WLF on the wavelength (3600A) is estimated to be: E3600 A = 7.54 × 1028erg. The estimated energy of WLF in the wavelength range (3590A- 6391 A) is: E=1.21 × 1031erg.
