Suspectedness is based on a single remark "Comp d seems to be weak; Estimate d 0 e" in 1924AN....221..101L for an Argelander type estimate sequence on BR Cyg with Comp d = 12.51 steps and Comp e = 16.38 steps on the average step scale.

Set coords to TYC-2 coords of GSC 3556-3202.
Set type to const: (GCVS ref 1666: F.W.Wright, HA 89, No.13, 1940 = 1940AnHar..89...21W).
Set max mag to Simbad V mag value for GSC 03556-03202 that fit recent V band obs.
Set amplitude to vis mag equivalent of Leiner's steps.
Added object remark on source of variability. |

ACP plots NSV 12298 to a blank space of sky just NE of GSC 3556-3202. Original source of NSV designation is GCVS REF 1666 F.W.Wright, HA 89, No.13, 1940. (See pp. 203 & 207 for reference to "d" comp star). Offset from 1900 coordinates given by Wright match in linear regression of recession, and 1923 coordinates by Leiner (see GCVS reference) fit as well. NSV 12298 = GSC 3556-3202 and is at position 19 40 38.80 +46 45 02.2 (2000), not 194039.6+464509 gieven by GCVS. B. Skiff agrees with this assessment as well (private e-mail). |
