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

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

They can be found here http://alpo-j.asahik...13/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.asahik...12/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!
