Simultaneous observation of Solar Events by Indian Payload (RT-2) and ICSP-VLF receiver.

We present the results of analysis of simultaneous observation of several Solar Flares (SF) by RT-2 Experiment onboard CORONAS-PHOTON satellite and ICSP-VLF receivers. The ionospheric response of the solar flare is clearly detected in the VLF signals. The hard X-ray event shows several pulsations especially in the 5th July, 2009 event, whereas in the VLF signal, we did not detect any such kind of pulsations. Such results are very useful in modeling the ionosphere, especially to understand the atmospheric chemistry. [ABSTRACT FROM AUTHOR]
