WebSolar corona is generally classified into active regions and the quiet solar corona. Active regions are defined as those regions of the solar corona which harbor strong magnetic fields and are bright in X-rays and extreme ultraviolet bands. Active regions are responsible for large explosive events like solar flares, coronal mass ejections etc. WebWe compared the data obtained by the analysis of recorded VLF signals and line spectra for different solar flares. In this paper we treated the DHO VLF signal transmitted from Germany at the frequency of 23.4 kHz recorded by the AWESOME system in Belgrade (Serbia) during solar flares in the period between 10:40 UT and 13:00 UT on 2011 April 22.
