The total solar eclipse of March 29 2006 was observed from Kastellorizo, Greece using, (a) a self

constructed monochromatic Lyot filter, tuned at the Fe XIV 5303 Ǻ, with a 4 Ǻ bandwidth, (b) a self

constructed spectrograph and © conventional photographic equipment. The Lyot filter was

constructed from first principles, using off the bench components. A short description of the

construction is presented. The active regions of the solar corona were observed with the above filter

and their distribution along the solar rim is presented. The flash spectrum, lasting a few seconds

before totality, was observed with the above mentioned spectrograph. Spectral analysis revealed a

series of emission lines in the solar atmosphere, which have been identified with distinct chemical

elements. The observed spectra are presented, after removing the corresponding continuum spectrum

of the Sun. Finally several high quality photographs, taken at white light, are displayed.
