eta Carinae.

VERVEER A. and FREW D.

Abstract (from CDS):

A. Verveer, Perth Observatory; and D. Frew, Macquarie University, report the following B and V photometry of eta Car obtained with a 40-cm f/11 reflector (+ Apogee AP7 CCD camera, using standard Bessell filters; comparison star HDE 303308) at Perth Observatory: June 5.526 UT, V = 4.72, B-V = +0.71; Nov. 20.7914, 4.665, +0.709; 21.7733, 4.655, +0.714; 25.7814, 4.665, 0.714. The photometry was summed through a 22" aperture and naturally includes the central binary star plus all of the surrounding Homunculus nebula; the recent HST photometry of Davidson et al. (IAUC 9094) refers only to the star itself and is about a half magnitude fainter.
