Abstract
ON the morning of the 7th inst. a curious form of sunrise-glow was observed on Ben Nevis. The sky at the time was covered by a uniform thin sheet of stratus-cloud lying just a little above the hill-tops all round. About 7 am., shortly after sunrise, the sun was shining downwards through this cloud, and the valleys to the eastward of Ben Nevis were filled with a “glow” exactly similar in colour and general appearance to the upper glow so often observed before sunrise and after sunset. The temperature at the time was very low—9°.2 F.—and at 7.16 a portion of a vertical halo passing through the sun's disk was seen. This “under-glow” would seem therefore to have been due to the presence in the air of ice-crystals, rather than of dust, whether cosmic or otherwise.
