Abstract
This paper describes an experiment carried out during an eclipse to determine the colour of the solar corona. It contains the results of the solar corona colour measurements during the total eclipse of 1994 near the solar limb. The difference in the colour of the corona and the colour of the photosphere might indicate the presence of neutral matter. Moreover, it theoretically indicates the colour according to the present model of the corona. On the basis of the results, it seems that solar corona should be redder everywhere than the solar disc centre even near the limb. The experiment shows that the corona near the limb is bluer than the centre of the solar disc, and this effect decreases with the height in the corona. We compared the results of the experiment with those of the theoretical calculation of the colour. This comparison shows that the experimental results are in agreement with the theoretical, above the height of 3′. This fact probably proves the presence of neutral hydrogen in the corona.
