Two possible observational exercises


These are quick suggestion without any introduction or preface. If there are any questions one may please us directly. We will answer those questions on these pages.  With the advent of modern digital cameras one can think of two observational exercises those amateur astronomers could try.


The Shadow Bands

The phenomena that takes place just before and after the totality (Check these links , Shadow bands during a total solar eclipse by Dr. Wolfgang Strickling ).

One could use their simple digital camera in the movie mode to try and capture the shadow bands.  Let the time be superimposed on the frames. In addition to the method suggested by Dr Wolfgang Strickling one might draw equidistant parallel line on the sheet spread  on the ground.  Try and keep the camera normal to the sheet.   


The Flash Spectrum

Web links (Flash Spectrum link 1  , Flash Spectrum link 2 )

One needs to be rather quick to record the flash spectrum (the spectrum of chromosphere) and  thus the phenomenon may best be recorded in movie mode. DVDs with their printed layers peeled away make good cheap diffraction gratings.  Put one in front of the camera lens. You can now see the spectrum of any source and can therefore record it too. Make the attachment in such a way that the grating can be rotated easily .

To record the flash spectrum, close to the totality phase when only a thin crescent of the Sun is seen in the sky rotate the grating in such a way that the spectrum is normal to the crescent sun.  Let the camera roll.  First you should have a broad continues spectrum soon you might see some absorption lines and when the photosphere is gone and only chromosphere is left you should be able to see the bright emission lines - the flash spectrum.

For making a simple spectroscope please visit IUCAA link A and link B .
