Star: Struve 3037 Date & Time: July 8-9 2003 Seeing: 6 [see http://www.backyard-astro.com/Logs/logsreport.html Transparency: 3/10 Location of site: 45°N // Tomahawk WI, USA Site classification: Rural Temperature: 65°F dropping to 50°F Sky darkness: 4/10 (Thompson Scale) Conditions: surprisingly minimal dew; slight breeze from the North Telescope: Meade 8" f/10 LX-10 (Snoopy ) Eyepieces: 32mm, 13.8mm, 9mm, 5mm Magnification: 63x, 147x, 226x, 406x				Visible split at 63x... at 147x the 'A' star was the color of muslin and was placed in the lower left corner of yet another keystone asterism. Also at 147x, the 'B' star resembled Mu Cephei.

Star: Struve 3037 Date & Time: 11 July 2003, 11:41 PM PDT Seeing: 6 <1-10 Seeing Scale (10 best)>. Transparency: so-so Location of site: Beaverton, OR, USA 45d 29' N, 122d 48' W Site classification: Suburban Temperature: Warm, mid-70's (F) Sky darkness: 4 <Limiting magnitude> Moon: Telescope: Takahashi FC-60 Eyepieces: 7mm UO ortho Magnification: app. 71x				The primary had just a hint of red to it and the secondary was a dim blue. Very wide separation.

Star: Struve 3037 Date: 13 July 2003, 01: 50hrs UT Location of Site: Northwich, Cheshire. UK (53° 15' N -2º 33' W) Seeing: 6 <1-10 Seeing scale (10 best)> Transparency: <1-10 scale (10 best)> Conditions: Clear sky with drifting high haze later. Moon bright. Site classification: Suburban Sky darkness: 3.0 ( UMi ) <Limiting magnitude>. Telescope: 4inch f/15 Vixen achromat. Mount: EQ5 Eyepieces: 9mm Orthoscopic Magnifications: X167				Another wide double star, easily split at this magnification. The primary star appeared to be a yellow/orange with a very faint white companion. I could only just record the dim companion at times due to drifting haze. At times, when in clear sky, I got the fleeting impression of a closer faint star using averted vision. I couldn't see it for most of the time though so couldn't confirm this.Probably needs a clearer darker sky.

Star:Struve 3037 Date: 29, July, 2003 , 23:45 -> 2:45 local time Location of Site: Sena de Luna, Spain 42.55N, 05.57W Seeing: 8->7 <1-10 Seeing scale (10 best)> Transparency: 8->7 <1-10 scale (10 best)> Other conditions: No Moon. Temperature:18ºC Altitude: 1,200 mts (3,940 ft) Site classification: Rural Sky darkness: about 5.5 Telescope: Takahashi FS-102 Mount: Vixen GP + Skysensor 2000 Eyepieces: 9mm Nagler, 5mm and 3.8mm Eudiascopics Diagonal: Zeiss prism diagonal Magnifications: 91x, 164x, 215x				Another "entry level" double. In any case, it's a very nice one, because some other faint stars (I would say between 10 and 11 magnitude) do appear near it, forming a nice asterism of five stars (multiple system??)

Star: Struve 3037
Date: 9, August, 2003 , 00:00 -> 02:30
Location of Site: Eext, The Netherlands
(53N, 06E)
Seeing: 4 <1-10 Seeing scale (10 best)>
Transparency: 7 <1-10 scale (10 best)>
Other conditions: No Moon.
Temperature: 20ºC
Altitude: 1,200 mts (3,940 ft)
Site classification: Rural
Sky darkness: about 5.5
Telescope: Celestron C11
Mount: Losmandy G11
Eyepieces: 40mm Pentax SMC XL,
20mm TV Plossl, 10mm plossl, 5mm LV.
Magnifications: 70x, 140x, 280x, 560x

STF3037 is another surprising double. It turns out to be a multiple systemen with more components than the one (@ 29.4") mentioned in the project.

Using 280x I noticed the real secondary (B) and despite the bad seeing it was a pretty sight (Harshaw rating: 2). The primary has a deep-yellow color.
These are the componets given bij WDS:

A - mag. 7.0
B - mag. 8.7 @ 2.6"
C - mag. 9.9 @ 29.4"
D - mag. 10.9 @ 52"
E - mag. ? @ 110"
F - mag. ? @ 125"

Star: Struve 3037 Date & Time: 4 and 5 Sep 2003 11pm to midnight Seeing: strange 5-7/10 but slow blurring Transparency: Fair Location of site: Silverdale WA, USA 47N 123W Site classification: suburb-rural Conditions: pleasant temps no wind Sky darkness: 5.4 <Limiting magnitude> Telescope: Celestron C8 Eyepieces: Video camera DX8263SL Magnification: 3x barlow app 1000x				Multiple star, the listed component is actually C. Yellow primary and all those faint companions are blue. Measurement: AB 2.8 sec at 211.7 deg PA, AC 29.64 sec at 189.6 deg PA, AD 52.26 sec at 232.4 deg PA. Components E and F are wide and were outside the 3x FOV. Note: my WDS shows a typo in AC reading 39 sec vice 29 sec.
