		BV 394 = BD+42deg3471 (8.9m)

	Observations by R. WEBER, Paris (communication by letter)
and K. HAUSSLER (communicated in Hartha Beobachtungs-Zirkular
1966, No. 34, 35, 36) proved our data concerning variability and type
of Cepheid of BD +42deg3471 (8.9m) given in Vol. VI, No. 16 of the
"Veroffentlichungen der Remeis-Sternwarte Bamberg".
	According to his observations HAUSSLER had already
derived a period on which we based our calculations. Because of the
large time-interval covered by our observations we could improve
the period and we had to enlarge it from 4.925 249d to 4.925 46d. The
period is accurate according to an interval of 2564 epochs (1932-1965).
	Magnitude-estimations of HAUSSLER have been fitted to our 
lightcurve.
	Elements: Max = 2426427.300 + 4.925 46d  E (Cep)
		  ptg. magnitudes: 9.4m - 10.3m (Fig. 1)
