YY Carinae = 123.1904 = HV 799
========================
since the variable was announced by Pickering in AN 166,35 (1904).
     E. Hertzsprung determined the period, 2.64264d (BAN 2,212, 1925) but did not update
the magnitude range. He did however publish a better position : (1875)
     Looking at the field, I see _no_ star of 10th mag. within 10 arcminutes of the
nominal position. In fact the nearest star to the position of YY Car is UCAC2 4756953
YY Car.
     Perhaps the explanation of the discrepant maximum magnitude lies in the remark by
Pickering himself. He states that this star was was near the edge of the plate examined,
and estimates of its brightness were made with difficulty.
observation of an eclipse.
