Jupiter and HR 1370

Finally finished the sketch of my observation on January 3d. I thought the alignment of the two moons and the star was really beautiful, especially with the red of the star contrasting the bluish white of the moons. I observed this one for about 3.5 hours, taking time out for dinner and a few short breaks.

You can split it, Ed. Keep at it about 300x.

Norme, last night I split it at 400x. At 320x I could tell it was a double but no split. Right now there is a front passing through and conditions aren't optimal.

It was really neat to see Jupiter with a 'fifth moon' last night.

Ed, Fine sketching of Jupiter and moons and the red star in the field is a real plus as the "wanderer" crosses in front.

Frank, funny you should mention HR 1370 as a 'wanderer'. The sum of a series of small observing errors on my part, as well as having an eye exam late in the afternoon, led me to believe I was tracking a fast moving asteroid the first night.

Ed,

very fine work. I love to see the moons in a Jupiter sketch. And HR1370 add a nice touch to your work!

Jean

After chancing upon the star HR1370/BU 87 near Jupiter on Jan 4 my research on the nature of this double led me to the various threads on CN. So perhaps my impressions may be of some interest.

They can be found here http://alpo-j.asahikawa-med.ac.jp/kk13/j130104z.htm (you will need to scroll right to the bottom!) which includes a routine drawing of Jupiter, and because of the very good conditions also includes details seen on the Galileans. With regard to the scale drawing of the satellites and BU 87 this is in relation to the stars’ separation, the stars themselves necessarily enlarged (about 6x in actuality!).

Some of my observing setup etc is shown here http://alpo-j.asahikawa-med.ac.jp/kk12/c121213z.htm

After checking on Sky Map Pro 11 I see that Jupiter passes through the field of R Gem in 2014 early January. After checking this star out on the AAVSO site it should be near maximum then as now – period 369.91; tho’ possibly fainter than mag. 7. With a B-V colour index of +2.2 it should be pretty much redder than BU 87; I plan to check this out at next opportunity. This is also double but the secondary fainter than mag. 12.

I am only recent signed to CN so please excuse any foul-ups!

David.

David, I checked out the links - Thanks. I'm impressed with the sketches, and that you can observe the detail on the moons. That is some serious hardware you have.

Ed, that's a great sketch. I love the addition of various stars when they are that close to planets in the eyepiece. Funny that you thought it was an asteroid initially. I can see myself conjuring the same thoughts. I agree with others that your color representations are quite enjoyable.
