Fomalhaut

Post by Christopher K. » September 8th, 2015, 11:17 pm

This lonely magnitude 1.1 class A star is the brightest in Piscis Austrinus, and it was twinkling forelornly low in the southeast about an hour ago. I used it to hop to Neptune. Although much dimmer than Vega it's only about a tenth of a light-year farther away. If weather permits, take a look between tonight and Thursday night to catch the twinkle.

Just out of curiosity I check out Fomalhaut at 10x Wednesday night right at its culmination (~10:30pm) to investigate its environs. Its nearest companion (at 10x anyway) is A-class magnitude 5.5 HIP113532.

Tonight or tomorrow night, look at Fomalhaut either unaided-eye or in a binoc. It definitely rules its area. The nearest first-magnitude star, Achernar, is dozens of degrees away (and besides, rises all of two-and-a-half degrees in Baton Rouge).

On November 19 at about 8:10pm CST a looked at Fomalhaut along with Beta Ceti and Ankaa. They form a nice, almost equilateral triangle (24.5, 22 and 26.75 degrees for the sides). I looked at Ankaa--a magnitude 2.4 star in the constellation Phoenix) with a Bushnell 10x; it twinkled but I saw its gold tint.

I took one last good look on 3 December at ~7:35pm (after its culmination) with a Bushnell 10x. Three-quarters of a degree NNE of HIP113532 is mag 5.5, K-class HIP 113669. Almost one-and-a-half degrees west of Fomalhaut is mag 6.0, G-class 21 Piscis Austrini. Curiously it is dimmer than the two HIPs yet has a Flamsteed number!

Fomalhaut will culminate at about 6:57pm CST tonight. About ninety minutes after this you should start to see (just) B-class, magnitude 1.6 Bellatrix peeking over the eastern horizon, signaling an oncoming of Orion and the rest of the winter sky.

Some say the only constants are death and taxes. The stars seem constant, though; most of them, at least during a human lifetime anyway. Expect Fomalhaut to make an appearance below the waxing gibbous Moon tomorrow night. The star should hit fifteen degrees at 9:57pm--and thirty degrees at 12:59am Tuesday morning!
