Primary was blue-white; the little secondary looked white
with possibly a faint bluish tinge.

Quite easy x47. Comes also seen and held with averted vision
x93. At the higher power, though, the companion is curiously more
difficult, although still fairly easy in absolute terms. The primary
is pure white, perhaps with a dash of blue. No colour seen in comes.
Estimated PA = 165 degrees.

Date & Time: 21-October-2000 ( 20:15 UT ) Seeing: 6-7 <1-10 Seeing Scale (10 best)> Location of site: Cheshire. UK 53° 15' N –2º 33' W Site classification: Suburban Sky darkness: 4.4 <Limiting magnitude> Telescope: 200mm f/6 Newtonian scope mounted over a Vixen GP mount (manual slow motion). Any Quoted PA or SEP using micro guide. Magnification: X120, ( X324 Microguide )
|
In the X120 magnification field of view the primary star
of this system seemed be a blue/white colour with the fainter companion
having a pale blue/purple colour.
A single measure using the Microguide at X324 gave the PA for the secondary to be 175deg and a separation of 35.4 sec

Again the bright 4.5 mag.
primary and relatively high altitude made this an easy star to find, lying
just North of Epsilon and Delta And. The wide separation in these
conditions also attracted me. Comments: This double was easy at low power
and the Primary appeared a Pearly White with the wide companion a crisp
Dark Blue.

84X yielded a white primary and blue-white secondary and
this time my observation agrees with Smyth and Olcott.

Location of site: Northern Kansas City, Missouri (USA) 94d 30m west longitude, 39d 15m north latitude 980 ft above Mean Sea Level Date of observations (UT): Nov 2, 2000 at 2330 Site classification: suburban Sky conditions: seeing-- 8 out of 10 (at times, approaching 9) transparency-- 7 out of 10 (high, thin and spotty clouds, taking perhaps 1magnitude from the starlight) limiting visual magnitude-- 4.0 mag Telescope: Celestron C-8 Eyepiece: 20mm, 104x |
Year of first measurement: AB 1821, 35.9 / 173;
AC 1879, 55 /357
Year of last measurement: 1992 Distance (light years): 660 Luminosity (in suns): 670 Eyepiece and magnification: 20mm, 104x Colors noted: W, L??, undetermined. Webb saw them as Y and B and mentions a distant 11.5 mag star. That 11.5 star ("C") is probably an optical interloper. It was discovered by William Herschel. Star A is a spectroscopic binary with a period of 143.606 days (the stars are less than 2 AU apart). There is a nice grouping of stars about 10' south of here. I rated the system a 4. |

I next tried for pi And.This was also easily found. Starting
from beta, which with mu, forms what I consider to be the pointers to the
M31 complex, and moving towards alpha, the next star visible is delta,
which is flanked on one side by epsilon, and farther away on the other
side is pi. However, at this time this was almost straight overhead, and
I couldn’t use the tripod. Handheld I could not split it. With due deference
to Eddy, I have a new dance, the Bino-Ze-Chacha. I must get that parallelogram
bino mount built!.

Est PA without inst...175d
Est the companion to be 4 mag dimmer than primary. Sky very washed out at this point. No observed color. Ambience: Hmmm. With the leaves gone the neighbors' yard lights are more obnoxious than ever. We are definitely going from fall to winter here. Lots of moisture in the air caused the Portland light bubble to reflect and lighten the sky to be very light. By 11:00 PM a ground fog had moved in and frost was forming on everything. |
