report: V and K band imagery of V1055 Ori (IAUC 5717) were obtained on
March 5.1 UT at the Hall 1.1-m and Perkins 1.8-m telescopes at the
Lowell Observatory using the Lowell RCA direct CCD camera and the newly
commissioned Ohio State Infrared Imaging System respectively. Digital
aperture photometry of these data gives V = 20.0 +/- 0.7 and K = 17.2
+/- 0.3, with the large error in the V magnitude attributable to the
small telescope and a bright background from the nearly full moon. Our
results are consistent with previous photometry of V1055 Ori (Machin et
al. 1990, MNRAS, 247, 205; Gottwald et al. 1991, A&A Suppl., 89, 367)
which give a mean V = 18.9 +/- 0.1 but with some intrinsic variability
of ~ 0.2-0.3 mag. Our photometry indicates that V1055 Ori appears to
be near its quiescent brightness and not in an unusual high state, but
the observations cover only one epoch. Additional photometric
observations are encouraged.
