Abstract

The paper presents the results of processing of data on the soft X-ray solar radiation obtained by the PINGVIN-M instrument aboard the KORONAS-FOTON spacecraft in July 2009. The high sensitivity of the device, combined with effective compensation for the magnetospheric background over most of the orbit, made it possible to study in detail the evolution of X-ray radiation from the active region and its X-ray bursts—from microflares to class-C bursts. The analyzed data refer to the period of deep minimum solar activity, during which there was only one active region emitting in the soft X-ray range on the solar disk. This made it possible to study the characteristics of soft X-ray radiation in this region without additional background with a device that records radiation from the entire solar disk, which significantly increases the reliability of the estimates of the parameters of the time and energy spectra of X-ray radiation derived from experimental data.

PINGVIN-M装置于2009年7月注册的太阳活动区NOAA 1024的软X射线辐射特征

摘要

本文介绍了2009年7月由KORONAS-FOTON航天器上的PINGVIN-M仪器获得的有关软X射线太阳辐射的数据处理结果。该设备的高灵敏度以及对磁层背景的有效补偿轨道的大部分区域使得详细研究有源区X射线辐射及其X射线爆发（从微耀斑到C类爆发）的演变成为可能。分析的数据是指太阳活动最小的深期，在此期间，太阳圆盘上只有一个活动区域在软X射线范围内发射。这样一来，无需使用额外的背景记录设备，就可以研究该区域中软X射线辐射的特征，该设备可以记录来自整个太阳盘的辐射，
