A Solar Eclipse provides us an exciting opportunity to study the Very Low Frequency (3 to 30 kHz) propagation effects under a controlled experimental condition where the extreme ultraviolet and the X-rays from the sun are totally blocked by the moon. So far we have studied three Solar eclipses in Indian sub continent and beyond using multi-station VLF campaign.
