             NEW CLASSIFICATION FOR SU COLUMBAE


  SU Col has been supposed to be a CW star with a period of P = 21.55d in
Veroff. Remeis- Sternwarte Bamberg 7, Nr. 76 (1968). On the basis of the
spectrum taken on this star, Dr. W.P. Bidelman, Cleveland, Ohio, doubted this
classification (communication by letter).
I found the following improved data:


    RR Lyrae star, Max. = 242 8763.655 + 0.487361d. E.


More details will be published in Mitt. Veranderl. Sterne, Sonneberg.
