G'day all,
Some of my observations of southern variables for December 3 (at last, a
clear night!).
Also noted: Eta Carinae was not its usual orange colour, although its
magnitude was typical of recent months. Visual examination with my 15cm
telescope at 214x revealed a star, pale greenish-white in colour, at the
centre of the "Homunculus" object. The Homunculus was its normal orange
colour (see Sky & Telescope Oct 1996 p13 for a recent HST image of the
Homunculus).
I speculate that I was looking at "the real Eta Carinae" through a gap
in the Homunculus. I wonder if it will be visible again tonight??
