DO Dra & other obs

SELECTED OBSERVATIONS OF VARIABLE STARS 
Observer   : Tonny Vanmunster, Landen, BELGIUM  
	     [VVS Belgium, Variable Star Section] 
	     Internet: tvm@lms.be 
Instrument : 0.35-m f/5 Newton  
 
Observations for May 17/18, 1994 
 
 
IMPORTANT REMARK : the list of observations  below  contains  two 
consecutive  magnitude  estimates  of DO Dra.  One entry is based 
on a sequence provided by Dr. Kato (VSLOJ) -CCD frame-, the other 
one is based on the TA (The Astronomer Group)  sequence.  DUE  TO 
DIFFERENCES  IN  THE SEQUENCES, THE RESULTING MAGNITUDE ESTIMATES 
DIFFER BY 1.0 MAG.  For this reason,  estimates  of DO Dra should 
always mention the used sequence and comparison stars,  in  order 
to  be useful for further processing,  as was also pointed out in 
the VVS Cataclysmic Variables Circular No.3.
