Abstract : VLF signal analysis is an effective remote sensing tool to study the conditions and disturbances in ionosphere and hence the level of activity in the sun. The observation of solar flares made during the months of April to June 2015 is presented. The electron density of the ionosphere during the flare onset is also assessed using the International Reference Ionosphere model (IRI). The VLF signals are recorded at receiver site located at Ettimadai, Coimbatore (10.8981°N, 76.9003°E) from the transmitting station VTX (17 kHz) located at South Vijayanagaram, Tuticorin (8.387014°N, 77.752761°E) with Great Circle Path of 294km. The GOES satellite x-ray flux data is used for determining the onset and duration of flare and thus the time delay at the receiver site is assessed.
