Abstract
AS already noted in NATURE (Feb. 13, 20 and 27), notable displays of the aurora were observed on January 7 and February 3, and it was anticipated there might be a recurrence after the 27-day interval of solar rotation on March 2. Weather was generally cloudy or overcast and unfavourable for observation on the last-mentioned date, but Mr. W. N. Craig, of Fortrose, Ross-shire, writes that an observer near Cambridge reported seeing the aurora between 20h. and 21h., with a maximum brightness at 20h. 45m. U.T., and another observer at South Queensferry, near Edinburgh, in a small clearing at 19h. 45m., noted the sky to be brighter than usual. Two persons near Stony hurst, in a brief partial clearing of the sky, reported seeing auroral rays between 20h. 20m. and 20h. 30m., and an observer in the vicinity of Preston noted indications of aurora with rays, between 23h. and 23h. 25m. On the other hand, Mr. W. B. Hous-man, director of the Aurora Section of the British Astronomical Association, observing over the Solway Firth from Seaton, Cumberland, reports: “On March 2nd there was no aurora seen throughout a cloudless night here, observations being at very frequent intervals”. On the Stonyhurst magnetic traces there was a moderate magnetic disturbance from 18h. 40m. to 19h. 40m., after which conditions were quiet, with only very slight movements.
