Date & Time: 6 July, 2001, 03:00 to 04:55, UT Seeing: 8 <1-10 Seeing Scale (10 best)>. Transparency: 6-7/10 ,variable, due to high hazy clouds Location of site: Northern Kansas City, Missouri. 39º 15' N, 94º 30' W, 980 ft above Mean Sea Level Site classification: Suburban Sky darkness: <Limiting magnitude> Telescope: Celestron C-11 Eyepieces: 25mm Plossl Magnification: 112x |
Position: 1842+2739
Magnitudes: 9.6 (A0), 9.9 Sep/PA's: 10= / 56= Year of this measurement: 1964 Distance (light years): 270 Luminosity (in suns): 1.4 Colors noted: bW, W Comments: It is a nicely
split pair, but overpowered by a 9m star NNW. It is part of a neat
little pentagram similar in shape to a baseball "home plate."

Date & Time: July/9/01 0500 to 0635 UT Seeing: 7 <1-10 Seeing Scale (10 best)>. Location of site: Killeen, TX, USA Site classification: Suburban Sky darkness: 4 <Limiting magnitude> Temperature: In the 80's F (30's C). Slight breeze. Telescope: Celestar 8" SCT Eyepieces: 25mm, 17mm, 10mm Magnification: 80x, 120x, 200x |
A dim pair, both close to
mag 10 and equal; but fairly wide spread. Easily split at low power. too
faint to detect color.

Date & Time: 17 July 2001 ( 22:30 UT ). Seeing: 6+ <1-10 Seeing Scale (10 best)>. Location of site: Barreras, Salamanca, Spain. Site classification: Rural,Suburban. Conditions: no moon, fairly dry but with gusts of wind. Sky darkness: 5+, some light due to street lights in the village. <Limiting magnitude> Telescope: Meade 7" Mak Cas mounted on a Losmandy GM8. Eyepieces: 12mm plossl Magnification: 223X Harshaw Scale: 2 <1-5; 1 best> |
Nice split at 223X. This double had a halo of stars above the double making for a nice view in the eyepiece. Easy to note the equality of magintudes in the double. Both white | |||

Date & Time: 21st, July, 2001. 21:00 – 23:05UT Seeing: 7-8 <1-10 Seeing Scale (10 best)> Transparency: 3-4 <0:worst -10:best > Location of site: Quintueles, Gijón, Spain. 43º 32N, 5º 55W. Altitude: 20 m. Site classification: Suburban Sky darkness: 3.0 - 3.5 <Limiting magnitude> Temperature: about 15º C Conditions: A lot of haze and moisture. Seeing is rather good, but haze actuates like a light diffusor and that makes difficult observe stars fainter that 10 magnitude. Humidity: about 90% Telescope: Vixen 102 4" achromatic refractor Eyepieces: 35, 10 and 5mm Baader-Planetarium Eudiascopics Magnification: 100x Harschaw Scale: 3 <From 1 to 5. 1 = Great, 5 = poor interest> |
Not a lot of effort to split, although every component is about magnitude 10, and this puts this double in the limit of this night's observing conditions. Anyway, the fact of not having practically difference of magnitude helps a lot. At first I need averted vision to split this double, but after a few moments, the split is clear with direct vision. | |||

No observable color. Clean split at 47x and 112x. Double anchors the southern
corner of a four star asterism shaped roughly like the square of Hercules.
The primary and companion were almost of equal

Easy at 40x, but the field
is what really caught my eye and it got sketched.
