This paper is an attempt to understand the physical processes occurring in different layers of solar atmosphere during a solar flare. For a complete understanding of the flare we must analyze multi-wavelength datasets, as emission at different wavelength originates from different layers of the solar atmosphere. Also, flares are transient and localized events observed to occur at all longitudes. With these considerations, we have carried out multi-wavelength analysis of two representative flare events. One event occurred close to the centre of the solar disk and other occurred close to the limb. In the former case, we examine the emission from the lower layers of the solar atmosphere. Therefore the chromospheres, transition region and also the photospheric magneto-gram can be analyzed. On the other hand, in near-limb event, coronal features can be clearly studied. In this paper, the first event studied is the M 1.1 class flare from the active region NOAA 10649 located at S10E14 and the second event is the M 1.4 class flare from the active region NOAA 10713 located at S12W90. In both cases, we have observed the excellent multi-wavelength data sets. The observations from multi-instrumental data clearly shows that flares occur in the vicinity of sunspots. These are regions of strong magnetic field with mixed polarity.

太阳耀斑发生期间能量过程的多波长研究

本文试图了解太阳耀斑期间太阳大气不同层中发生的物理过程。为了全面了解耀斑，我们必须分析多波长数据集，因为不同波长的发射来自太阳大气的不同层。此外，耀斑是观察到在所有经度发生的瞬态和局部事件。基于这些考虑，我们对两个有代表性的耀斑事件进行了多波长分析。一个事件发生在靠近太阳盘中心的地方，另一个事件发生在靠近边缘的地方。在前一种情况下，我们检查来自太阳大气下层的发射。因此可以分析色球、过渡区域以及光球磁图。另一方面，在近肢事件中，可以清楚地研究冠状特征。在本文中，研究的第一个事件是来自位于 S10E14 的活动区 NOAA 10649 的 M 1.1 级耀斑，第二个事件是来自位于 S12W90 的活动区 NOAA 10713 的 M 1.4 级耀斑。在这两种情况下，我们都观察到了出色的多波长数据集。多仪器数据的观测清楚地表明，耀斑发生在太阳黑子附近。这些是具有混合极性的强磁场区域。多仪器数据的观测清楚地表明，耀斑发生在太阳黑子附近。这些是具有混合极性的强磁场区域。多仪器数据的观测清楚地表明，耀斑发生在太阳黑子附近。这些是具有混合极性的强磁场区域。
