Star: Struve 2362 
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:  1838+3603 
Magnitudes:  7.2 (A5), 8.8 
Sep/PA's:  4= / 184+ 
Year of this measurement:  1969 
Distance (light years):  318 
Luminosity (in suns):  13 
Colors noted:  Y, bW 

Comments:  A nice pair set in a rich field (although the field within one FOV is not that great).  Webb saw them as yW and B. 
The first PA measure was 180deg; no change in separation.

A very nice view with 67x and 133x. At 67x the pair is tiny but very attractive. They show a yellow and bluish color.

Star: Struve 2362
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: 200x
Harschaw Scale: 4 <From 1 to 5. 1 = Great, 5 = poor interest>
The split is easy at 200x, although the sky's limiting magnitude makes a bit difficult to observe it  well. Maybe the real values of magnitude are fainter than the ones given in Burnham. In any case, I check if dew is starting to form in the objective and no, there is no dew. Anyway, I use the
technique of "hot cloth" to the refractor. This technique is described in the following paragraph:

First, I heat up water until almost reaching the boiling point and then put it inside a glass bottle. Around this heated bottle, I put a cloth made of wool. Then, from time to time (let's say, every two observed doubles or so), I put the wool cloth around the tube, just near the lens cell. Since doubles
in Lyra require that the tube is almost vertical, you must apply your hand at least for a minute or two. The ausence of dew is guaranteed!

Star: Struve 2362 (& T Lyr)
Date & Time: July 28 2001
Seeing: 6.5 <1-10 Seeing Scale (10 best)>
Location of site: Canada
Site classification: Suburban
Conditions: Clean skies and warm temperatures.
Sky darkness: 4.5 <Limiting magnitude> 
Telescope: 6inch/f5 newt
Magnification

 

A disappointing field at 40x; too sparse. 85x bettered the field and resolved the pair - a *** for me - and made me think of the field of STF 2333 by its isolation (strange considering the nearness to the Milky Way). T Lyr. "Red as ever but not very luminous. ~ 8½"

Location of site: Lake Oswego, Oregon 
Site classification: Suburban
Sky darkness: 4.3 <Limiting magnitude>
Sky: Full moon plus 6 days in Taurus
Telescope: 8 inch LX50 SCT

The companion seems much dimmer than the primary
in spite of published magnitudes.
The double is set in a very sparse FOV.
