So far as these prints and the negatives fromwhich they are made are concerned, there seems to be unmistakable evidencethat either the general brightness, or the extent, or the amount of unpolarisedlight, or all three, were greater on the north-east side of the sun than on anyother side; that is on the side where the great prominence was visible. Thiscan be seen on both the simultaneous photographs. The curved lines of the plume of coronal streamers to the north and southof the great prominence have their convex sides towards the prominence, so Porter and Coif ox. Roy. Soc.
