The Solar Vase
When the Sun or the Moon are low upon the horizon, the most curious distortions are to be seen at times. On still, cloudless days the layers of different density are less disturbed during their formation, so that the distortions of the Sun’s edge are more frequent and may be taken to indicate a steady condition of the atmosphere, as well as a sign of fine weather. These phenomena enter their most interesting stage usually only ten minutes before sunset or last until ten minutes after sunrise. In the picture, as the Sun was rising from the Tyrrhenian sea, some atmospheric layers of discontinuity drew the star in a Solar vase shape. The sunrise was recorded from Stintino – Sardinia island – Italy.
