An Extract of a Letter
I received the account of the Parhelia's, seen Ianuar. 30th last, st. n. about one of the clock in the afternoon, over the City of Cassovia in Hungary. It was communicated to me from a Learn'd Iesuit, call'd Father Michel, who lives at Presburg, but is now in this City, There were two Parhelia's, one on each side of the true Sun, and they were so resplendent, that the naked Eye could not bear the brightness thereof. One of them (the lesser of the two) began to decay before the other, and then the other grew bigger, and continued well nigh two houres, projecting very long rays from it self. They were both on that part, which was towards the Sun, tinged with a pale yellow, the other parts being somewhat fuscous. There were at the same time seen several Rainbows, together with the Segment of a great white Circle, of a long duration, pulling through the two Pathelia's and the Sun: and all this at at time, when the Air was almost free from Clouds, though here and there were scatter'd some very thin-ones.
