Abstract:
The results of 1424 speckle interferometric observations of double
stars, made with the 26 inch (66cm) refractor of the US Naval
Observatory, are presented. Each speckle interferometric observation
of a system represents a combination of over 2000 short-exposure
images. These observations are averaged into 1053 mean relative
positions and range in separation from 0.36" to 61.92", with a
median separation of 10.31". This is the 13th in a series of papers
presenting measurements obtained with this system and covers the
period 2006 January 12-December 29. Included in these data are nine
older measurements whose positions were previously deemed possibly
aberrant but are no longer classified this way following a confirming
observation. This paper also includes the first data obtained using a
new "secondary" camera, designed and built at USNO.

Note (1): Object notes as follows:
C = Confirming Observation
P = Given the proper motion and time since the last observation,
this pair is identified as a common proper motion binary
1 = Also known as BEM 15.
2 = Earlier 2004 data not published (Mason et al., 2006,
Cat. J/AJ/132/2219) due to larger than expected positional change
3 = Earlier 2005 data not published (Mason et al. 2006,
Cat. J/AJ/131/2687) due to larger than expected positional change
4 = Also see Table 1
5 = Hyperbolic orbit to this pair given in Hopmann (1967MiWie..13...49H 1967MiWie..13...49H)

Note (1): Flag as follows:
C = System used in calibration
* = System used in characterizing errors
1 = This measure was inconsistent with previous measures, so not
included in Mason et al. (2006, Cat. J/AJ/131/2687). However,
available data are deemed insufficient for a new orbital
calculation at this time
2 = This system was expected to show significant motion over the
calendar year, so multiple observations have been obtained

Note (1): Notes as follows:
1 = The DM cross reference given in Couteau (1966JO.....49..221C 1966JO.....49..221C)
does not match the coordinates in the paper, but the pair is not
found at either location
2 = Hipparcos "suspected nonsingle" (Perryman et al. 1997, I/239,
field H61), possibly due to input catalog listing, but no
indication of duplicity here
3 = Three measures from 1874 to 1894 (Wilson & Seabroke 1875, MmRAS,
42, 59; 1877, MmRAS, 43, 105; Glasenapp 1895, Mesures
Micrometriques d'Etoiles Doubles Faites a St. Petersbourg et a
Domkino, Vol. 3 (St. Petersburg: Impr. Acad. Imperiale Sci.))
and nothing since. Since 1894 the AB pair has been measured 67
times with no accompanying measure of the wide pair
