Abstract:
Results of 2433 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
1013 mean relative positions and range in separation from 0.96" to
58.05", with a mean separation of 13.50". This paper is the 15th
in the series of papers and covers the period 2008 January 3 through
2008 December 21.

Note (1): Notes as follows:
C = Confirming Observation
P = Based on proper motion of the primary and the time
since the last observation, this pair appears to be physical.
1 = Big change in position since the discovery in Baillaud
(1943, Ann. Obs. Besancon New Ser., 3, 33 ).
2 = The 2007 measure, being of lower quality and very different from the
discovery measure of Aitken (1901LicOB...1...66A 1901LicOB...1...66A), was not included in
Mason et al. (2008, Cat. J/AJ/136/2223). With this confirmation the
earlier measure is presented as well.
3 = Partial elements in Hopmann (1960MiWie..10..227H 1960MiWie..10..227H).
4 = The 2007 measure was very different from the discovery measure of
Soulie (1983A&AS...54..281S 1983A&AS...54..281S) and was not included in Mason et al.
(2008, Cat. J/AJ/136/2223). With this confirmation the earlier measure
is presented as well.
