[vsnet-id 199] CP Dra in 1904

[Brian Skiff <bas@lowell.edu>]

     I have examined Dorothea Roberts' 1914 report in the "Astronomische
Nachrichten" 197, 57.  This includes a reproduction of the April 1904 plate
along with some annotations about the mysterious mag. 13-14 star.  The position
given is derived with reference to Astrographic Catalogue stars measured by
Roberts and reduced by Pourteau:  10 07 04.84  +73 55 48.1 (1900), which
precesses to 10 15 40.6  +73 26 04 (2000).  Comparison of the plate with the
DSS indicates that the object is indeed CP Dra, visible at about red mag. 19
on the POSS-I plate at:  10 15 39.8  + 73 26 06 (2000) by my estimate using a
SkyView image.  The star is not in USNO-A2.0, but visible without difficulty
on the DSS image.  (It is neither in the AC2000 or GSC.)  I note that the
Downes & Shara chart does not really show the object, and even the 1997 edition
does not give a precise position.
