Date & Time: 5/26/00, 10 p.m. EDT Seeing: 6 <1-10 Seeing Scale (10 best)> Transparency: 5 Location of site: Englishtown NJ, 40.25 N 74.333 W Site classification: Suburban Sky darkness: ?? <Limiting magnitude> Telescope: 8 inch Dob Magnification: 47x (26 mm)

Viewed this star as a primary with a very dim faint companion
(only one seen). The separation was quite close but resolveable. Colors
were primary orange and the secondary a very dim blue.

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): 29 May, 2000; 0330 hours Site classification: suburban Sky conditions: Seeing-- 8 out of 10 (long periods of 10!!) Transparency-- 8 out of 10 Limiting visual magnitude-- 4.5 Telescope: Celestron C-8 Eyepiece: 10mm Ortho (211x) |
Magnitudes: 4.2 (F6V), 12.9, 10.9
Sep/PA's: AB = 48/73, AC = 70/62 (both seps are increasing and both PAs are decreasing) Year of last measurement: 1988 Distance (light years): 62 Luminosity (in suns): 6.3 A diffraction mask was a surprising help here as it "cleaned up" the image of A a great deal, turning a somewhat rough image into a sharp Airy disk and two diffraction rings with 6 perfect spikes. (I have often noted how a diffraction mask sharply improves bright star image quality and can't help but wonder if the central restriction caused by the SCT's secondary mirror doesn't extract a higher price in image quality than most SCT's owners would concede.) I had to nudge A to just off the edge of the field to let B pop out, even with the mask. C was much easier. Colors of White, ??, and White.

Date of Observation: 5/30/00 22:30UT Location of Observation: Ciudad Rodrigo, Salamanca, Spain 40º 36' N, 6º 32'W, Elev. 800 Meters Seeing: 4 to 5 (1 - 10, 10 best) Transparency: 6 to 7. Limiting Mag. (naked eye): 4 Site classification: Urban Instrument: Meade 8"SCT Magnification: 167X |
Separation (Clear or Touching):Clear (Easily split brighter two components).
Magnitude Comment: Primary and 10.9 component in accordance with data. Thought I could see 12.9 mag with averted vision between the two but was not sure. Color comment: Bluish primary white component General Comment On a nite of poor seeing these dim secondary components are hard to find and see.

Date & Time: Wednesday, June 29th 2000 10 -11p.m local; UT +10 Seeing: 5-6/10 <1-10 Seeing Scale (10 best)> Transparency: 7/10 Temperature: 7ºC, Light breeze. Location of Site: Terara, New South Wales, Australia, Long.150.38 degrees; South 34.52. Site Classification: Suburban Sky darkness: Northern sky to mag. 4.5; Southern to 5.5 <Limiting magnitude> Instrument: 8" F9 Dobsonian Magnification: 72x (25mm K) |
This star is easily located in the centre of a wide triangle
of mag. 4.5 stars. The primary has a marked greenish hue and the wide 10.9
and 12.9mag. dim companions are nicely clustered close together.
