Analyzing e-CALLISTO Images: Sunspot Number, 10.7 cm Flux and Radio Solar Bursts
This paper investigates on the sun’s activity based on sunspot images using time series of sunspot numbers and absolute 10.7 cm flux that would also enable to establish relationship between these indices and provide possible forecasts. Moreover, these indices are also compared with the monthly number of solar bursts detected by the Mauritian Radio Telescope which forms part of the e-CALLISTO network.

I would like to thank Dr. Beehary of the Physics department of the University of Mauritius as he was the one who provided the data from the Mauritian Radio Telescope and all those working at MRT for gathering the data.
