OBSERVING
FROM WHERE YOU AREWhat it takes to see 2MASS J11011926-7732383 for yourself. Everything in this part of the page is worked out for a real horizon, a real night and the equipment you say you have.
Say where you are, and this line says when 2MASS J11011926-7732383 is worth going out for.
THROUGH AN EYEPIECE
150 MM TELESCOPE · 25 MM EYEPIECEIts brightest companion sits 1.40″ away, which at 48× is right at the limit — a steady night and a good eye.

A is where the pair was the year it was measured — the ones above, in 2015, and a pair in a real orbit has moved since.
APPARENT PLACE
EQUINOX J2026.8Where a telescope has to be pointed today, which is not quite where the catalogue records the object: the coordinate grid itself has turned since the year 2000 the catalogue is referred to.

- none published
Computed for 2026-10-23 00:00 UT. No proper motion is published for 2MASS J11011926-7732383, so nothing here moves the object; what separates this from the catalogued position above is the coordinate grid turning under it — about fifty arcseconds a year of precession since 2000, and the small nodding of the Earth’s axis on top of that. The catalogue it came from publishes no error for that position, so nothing here says how far this arithmetic can be trusted — the digits above are as precise as the place they were computed from, and no more. Aberration, parallax and refraction are left out. Aberration swings every position by up to twenty arcseconds over a year; parallax stays under an arcsecond for all but the nearest stars; refraction is nothing overhead and about half a degree at the horizon, where it answers to the air, not the sky. The same figure for any date.

Separation and position angle are as measured in the year given; a position angle is measured from north, through east. Washington Double Star Catalog 11013-7733.
CATALOG DATA
4 FIELDSThe raw catalogue values, as the source published them, with the error bars where one was published — sorted by what each set of figures is about rather than by the order they happened to be stored in.
THE ORBIT
The shape of the path, where the object sits on it, and the instant those figures were true of. An orbit is a fit to observations and drifts away from the real one either side of its epoch.

1 SERVICEEach link carries the identifier printed beside it. Nothing on this page is a measurement of our own, so a number that disagrees with one of these is worth reporting — and a service that has never catalogued this object under this name will say so plainly.
