Solar observing with a Cooke


Mr. A. M. Newbegin, observing at Sutton, Surrey, with a Cooke photo-visual equatorial refractor and modified Evershed spectroscope, has continued his regular programme as in former years, recording the position-angles and heights of solar prominences. The results for 1922 were published in the B.A.A. Journal, Vol. 33, No. 6.
