   DK Sge = GR 41 was discovered by Romano in 1958 (Romano, G., Oss.
"Ariel" Publ. No. 14). The elements given by discoverer (First 
Supplement GCVS 1960) are as following:

   Min.= JD. 2435630.400+0.310896d * E    (11.9m-12.7m EW).

I examined this star on sky patrol plates (n=220, JD. 2436810.-41570.).
It turned out that the period should be doubled.
The improved elements are:

   Min.= JD. 2435630.400+0.6218188d * E (EB)
           (12.1m - 13.7m / 13.5m)
