The following doubles form a one degree rhombus in the whispering eddies north of Arcturus. The orange 7thmv star SAO 83251 at 14h 15.0m +23° 41' precedes the box delineated by these doubles, and, aside from the doubles, the box contains eight other stars from 9th to 11th magnitude. All four pairs were observed with my 20cm reflector.

 

HWE 32   14h 16.3m +23° 21'    9.92, 10.61   4.6"   194°   (2018)   Reddish-white, purple. 11thmv companion np. At low power, a coarse 9th, 10thmv pair nf.   40X, 143X

 

STF 3083   14h 19.7m +23° 30'   9.03, 10.98   4.8"   233°   (2018)   G0   Orange, violet. 11thmv companion nf.  143X

 

HJ 2708   14h 19.0m +24° 06'   10.95, 11.08   22.2"   314°   (2015)   F8   Reddish-white, bluish-white. 10thmv companion nf.   143X

 

STF 1828   14h 17.0m +24° 12'   10.40, 10.75   2.1"   159°   (2018)   F2   Copper, brown. 11thmv companion sp.   200X

 

None of these box-corner doubles are spectacular targets, in and of themselves. But as a package, I think they murmur a quiet dignity in the backwaters of Boötes.

You could add a couple more in the area:

 

BU 1441 is not far from HWE 32, it's at 14h 16.6m, +23 29 (J2000), mags 10.1 and 11,6, 3.6" at PA 079 (2002).

 

Also, ROE 74, a bit soth from HWE 32, 14h 15.6m, +22 55, mags 10.5 and 11,0, 7.1" at PA 287 (2011).

 

These should certainly be visible with an 8-inch.

Thanks for the suggestions. The primary of BU1441 is apparently the brighter star of the coarse pair I noted nf HWE 32. Although plotted in Millennium Star Atlas, it is not indicated as a double. ROE 74 is not plotted at all in MSA, but I have penciled its position into the atlas for when I re-observe the area. Thanks again for the extra bows to the box! wink.gif

Great title, Van Jan!

You most certainly do have an astounding imagination to dream up that one - a Boötes Box of Whispers. 

I like it! waytogo.gif  

 

I notice none of these doubles appear in Burnham. 

But doesn't matter. 

It is still very much a splendid report. 

 

I wonder who HWE refers to. 

It's nice to know there is a BU 1441 and a BU 1442 in Boötes. 

 

I reckon if I observed STF 1828 I would be rather pleased with it. grin.gif

 

Clear skies from Aubrey.

Hi Aubrey,

 

I'm going to guess HWE is Howe?.

 

I'm sure I've read that somewhere.

 

Rich.

Pure poetry there.bow.gif .

 

Next time out. I shall take a peek at the quite dignified backwaters of Bootes, and try for this one degree rhombus, and listen for the whispering eddies etc.

 

How cultured and civilised are you!!!!.lol.gif

 

Rich.

fred1871 - As you predicted, I successfully split both BU 1441 and ROE 74 with my 20 cm reflector. choo-choo.gif

 

BU 1441 - Pale red, no color. 10thmv companion sp. 250X

 

ROE 74 - Both white. 143X, 200X

Lovely writing style, I shall have to try these!

 

Almost exactly 4° N of Arcturus (ca. 19° 12').

Bu1441 is turning out to be an elusive target. The primary is easy enough to see in a 6-inch refractor but the secondary is doing its best to play hide-and-seek. Under a full moon using an 8inch f6 I could not see a double star. What is adding to the mystery is vanjan's observation of the PA being sp (south preceeding?). SD as well as Fred say it is 80 degrees or roughly following.

No, the 10thmv companion sp is an additional star in the field of view, not the secondary of the double.

I wouldn't expect to see the fairly close and rather dim companion to BU 1441 with a 6-inch scope and a nearly Full Moon. An 8-inch with much less or no Moon I would hope to see it unless in bad light pollution or outright bad seeing.

July 1 2021 saw a clear and moonless sky. In a mak-newt 8-inch f6 I tracked down BU1441 once again and saw a small and very dim spike of light in the correct PA. Under my light polluted conditions this companion is a very faint averted vision object. Perhaps VanJan could describe his observing conditions. Mine are, simply put, pathetic. I will re-observe this pair when I attend a star party under much darker skies

 Perhaps VanJan could describe his observing conditions. 

 

Typically, my NELM is around 4.0 to 30° off the horizon. Seeing, of course, varies, but it is rarely abysmal and never exceptional. I try to observe an object as close to meridian passage as possible for the best conditions of both transparency and seeing.

 

You are to be commended for your repeated attempts at BU 1441. waytogo.gif  Glad you finally saw it. goodjob.gif
