Abstract : | Solar flares ranging from small microflares to large X-class flares are
believed to be the result of sudden release of magnetic energy in the
atmosphere of the Sun. Measuring the distribution of various flare parameters
over a wide range of flare intensities provide a good opportunity to
investigate the scale invariance of the underlying physical processes. Solar
X-ray Monitor (XSM) on board Chandrayaan-2 has been observing the Sun for more
than three years, providing soft X-ray spectral measurements and has detected a
many flares from sub-A class to X-class. XSM data provides a great
opportunity for statistical studies of the solar flare parameters. For this
purpose, we developed an automated flare-detection algorithm to identify the
different flaring episodes from the XSM light curves that provide the start and
end times of the flares in addition to the peak time. As the XSM observations
often have gaps due to the Sun being out of its field of view, the algorithm is
designed taking these gaps into consideration. The algorithm is applied on the
XSM observations during its primary observing seasons to generate a flare
database which is planned to be reguarly updated and made available on the XSM
website along with additional information of the flares from other sources.
Here we present the details of the flare detection techniques and the results.
We also discuss the preliminary flare parameter distributions and their future
potential.
