While making observations of sunspots on April 5, 2006 by optical solar telescope (Celestron 5” reflector) with advanced high resolution digital CCD camera, we observed a solar flare on the eastern limb at 08:09:46 UT and an ejected blob of a solar material at 08:14:34 UT, probably emitted due to Coronal Mass Ejection (CME) behind the eastern limb of the sun. After processing the images using ‘Digital Image Processing’ techniques, we conclude that there must be an existence of a group of sunspots behind the limb of the Sun, which are closely associated with these two events. During the period 9-14 April, the sunspots regions 870, 871 and 872 came on the front side of the sun due to solar rotation. The data from SOHO-EIT, LASCO, GOES-SXI are used for the comparative study of these two events. In this paper, an attempt has been made to suggest a model responsible for the occurrence of these events in quick succession.
