VIRGO太阳总辐射测量中耀斑的特征

The Signature of Flares in VIRGO Total Solar Irradiance Measurements

摘要:

我们使用总太阳辐照度(TSI)测量的VIRGO(太阳辐照度和重力振荡的变化)仪器上SOHO获得的X级太阳耀斑发射的平均总辐射能量的初步估计。基本工具是总历元分析,这也使我们能够检测和部分描述基本数据中存在的系统误差。我们描述了这些错误,显着降低在高频率的光度。我们发现GOES 1- 8AA光度与总测热光度之比为0.01量级。

英文摘要:

We use Total Solar Irradiance (TSI) measurements from the VIRGO (Variability of solar IRradiance and Gravity Oscillations) instrument on board SOHO to obtain preliminary estimates of the mean total radiative energy emitted by X-class solar flares. The basic tool is that of summed-epoch analysis, which has also enabled us to detect and partially characterize systematic errors present in the basic data. We describe these errors, which significantly degrade the photometry at high frequencies. We find the ratio of GOES 1-8\{AA} luminosity to total bolometric luminosity to be of order 0.01.
