                          V 450 Lyr

V 450 Lyr = GR 250 was discovered by Romano (I.B.V.S. No. 645, 1972).
The discoverer classified the star to RR Lyrae type.
I examined the star on 97 sky patrol plates of Sonneberg Observatory
(JD 2438370 - 41984) and confirmed the RR Lyrae type. 12 maxima were
obtained and the following elements:
             Max. hel.= JD 2438370.285 + 0d.5046104.E
                        RRab; M-m = 0p.15

                                DL Sge

DL Sge = BD +18deg3960 (9,5) = Wr 111 was discovered by Weber (I.B.V.S.
No. 6, 1962). The discoverer classified the star as an eclipsing 
binary with the following preliminary elements:
             Min. hel.= JD 2437099.465+0d.8573.E (11m.9-12m.8)
On 501 sky patrol plates of Sonneberg Observatory I examined the
light variations (JD 2426089 - 42009) and obtained the improved
elements:
             Min. hel.= JD 2426089.553+0d.8572706.E
                        EA; 11m.40-12m.22/11m.5pg; D=0p.22
64 observed minima and further particulars will be published in
"Mitteilungen der Bruno-H.-Burgel Sternwarte Hartha, Heft 8".
