I was intrigued by an interesting, though dated, article about the elusive, and apparently greenish, companion of Alpha Scorpii that I read in R. Burnham Jr.'s Celestial Handbook. Burnham states that it might be easier to view Antares' companion star during a lunar occultation when the companion emerges from the darkened limb of the moon before it's parent star, while the glare of the bright parent star is obscured by the moon. Has anyone ever observed this during an occultation?
I tried to view the companion sporadically this summer with no luck. I used powers from 40x up to 333x with no luck. At lower powers and naked eye Antares appears orange with a hint of oscillating blue and white. At higher powers (>100x) the colors incorporate green and red into the oscillation. The colors may be a product of viewing the star so low to the horizon at my latitude, that atmospheric interference is playing a large role in the appearance of the star. I assume that it may be easier to split the pair while viewing near or south of the equator.
My main questions are:
1. At what power(s) have you successfully viewed Antares' companion?
2. What colors did the two stars appear?
3. At what latitude did you observe them?
4. What was the P.A. of the companion?
5. About how far from the parent was the companion (minutes/seconds)?
