Abstract:
The results of 2033 intensified CCD observations of double stars, made
with the 26 inch refractor of the U.S. Naval Observatory, are
presented. Each observation of a system represents a combination of
over 2000 short-exposure images. These observations are averaged into
1297 mean relative positions and range in separation from 0.54" to
58.96", with a mean separation of 14.99". This is the 14th in
this series of papers and covers the period 2007 January 17 through
2007 December 31. The first two resolutions of closer companions to
previously known wider pairs are also presented.
Description:
This is the 14th in a series of papers from the U.S. Naval
Observatory's (USNO) speckle interferometry program, presenting
results of observations obtained at the USNO 26 inch telescope in
Washington.

Note (1): Notes as follows:
C = Confirming Observation.
O = Based on proper motion of the primary and the time since the last
observation, this pair appears to be optical.
P = Based on proper motion of the primary and the time since the last
observation, this pair appears to be physical.
1 = Partial elements in Hopmann (1967MiWie..13...49H 1967MiWie..13...49H).
2 = Also known as TDS2606.
3 = Poor agreement with the 1895 discovery measure
(Δθ=64°, Δρ=3.6") is apparently due to
a typographical error in the Potsdam Observatory Catalog used by
Scheiner (1908, Publ. Obs. Potsdam, 20, Pt., 2, 59) for extracting
possible doubles. Matches by GLW to other Astrographic Catalog plates
from 1929 and 1930 are in good agreement (3.3°, 0.74") with the
present measure. The discrepancy cited here was noted by Ed Wiley
(private comm.).
4 = new, closer pair to a known double. See Table 1.
5 = Partial elements in Hopmann (1960MiWie..10..227H 1960MiWie..10..227H).
6 = Partial elements in Zeller (1965AnWie..26..107Z 1965AnWie..26..107Z).
7 = Pair noted by Ian Coster (private comm.) while investigating SHR 1.
This is the first measure of this pair.
