imaged ARY 51 (Halifax)

Tried to sort another "neglected" double star...

I used the data culled from an old list for 09390+3017 ARY. It showed data from 2003 with a position angle of 273 and an angular separation of 116.4. Magnitude 9.1 and 9.4 stars, one of which was a K2.

I programmed the Burke-Gaffney Observatory robot to acquire some photons from the distant suns in Leo.

neglected double-star ARY 51 in luminance

Luminance only, 1 second subexposures, 12 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

Clearly there's a very wide pair of stars, nearly perfectly horizontal, nearly equal in brightness. So, not a lot to write home about.

A pair of stars shows in SkyTools at this location. SAO 61616 on the left or east and SAO 61615 to the west.

This is the last neglected done via the old technique...


I checked the current data for the system.

ID 09390+3017
discoverer ARY  51
pair AB
first report 1903
last report 2017
angle 273
first sep 116.4
last sep 118.7
mags 9.15 and 9.55
precise 093859.33+301631.6

It's interesting that the first reporting appears to have been rolled back 100 years.
