According to my own experience, the Aurora with arches arranged longitudinally, thus,
, is the rarest of all the forms. I have not met with it myself, nor do I recollect an illustration of one other than Prof. Smyth’s.
CHAPTER IV.
PHENOMENA SIMULATING AURORÆ.
Auroric Lights (Kinahan).
Mr. Kinahan’s Auroric Lights. White and red. White light appears in pencils radiating from a point.
Mr. G. Henry Kinahan writes to ‘Nature,’ from Ovoca, under date January 27th, 1877, and speaks of two distinct kinds of light so classed—one brilliant and transparent, of a white yellowish-blue or yellowish-red colour, while the other is semi-opaque and of a bloody red colour, the latter being considered in Ireland a forerunner of bad weather. The first kind generally appears as intermittent pencils of light that suddenly appear and disappear.
Frequently not stationary, but jumping about.
