     Due to the wide public access to the Internet during the last
decade, the Central Bureau has experienced a significant, sustained
loss in paying subscribers -- at a gradual-but-steady rate that now
has the total paying subscribers to these Circulars (printed plus
electronic) down by about a quarter in the last five years.  We
have been reluctant to raise prices for fear of losing more paying
subscribers, and indeed no such increase has occurred in the past
decade.  Readership of these Circulars is way up over the past
decade, due both to the former free availability of them at the
CBAT website and to over-liberal distribution within institutions
(and groups) that have single (or no) paid subscriptions.  However,
subscription funds are still necessary for the work behind issuing
these Circulars, so we have initiated two immediate actions:  (1)
to block (at least temporarily) free online access to these
Circulars in favor of our paying subscribers and (2) to request
that all groups and institutions with multiple readers take out
'multiple' subscriptions (a concept that is paralleled in
subscriptions to other astronomical journals in the sense of
'institutional rates').  We propose that groups and institutions
pay their subscriptions as follows:  5-10 readers, twice the single
rate; 11-20 readers, 3x; 21-30, 4x; 31-60, 5x; 61-90, 6x; 91-130,
7x; 131-180, 8x; 181-250, 9x; 251-320, 10x; 321-400, 11x; 401 or
more, 12x.  As has always been the case, astronomers (and groups)
with limited funds can ask for aid in reducing the subscription

     R. Persson, Hindas, Sweden, reports that a USNO-B1.0 star
located at R.A. = 22h53m33s.28, Decl. = +62o32'23".1 (equinox
2000.0; blue mag 20.2, red mag 15.7) was not visible on a red
Palomar Sky Survey plate from 1953 October, but it is present on
digitized Palomar Sky Survey plates taken on 1991 Sept. 2 (red, mag
about 15.7) and 1984 Aug. 28 (Quick-V).
     B. Reipurth, University of Hawaii (UH); and C. Aspin, Gemini
Observatory, report that an R-band CCD image obtained at the UH
2.2-m telescope on 2004 Oct. 9 shows that this star (at R about
17.3) is located at the apex of what appears to be an outflow
cavity in a small dark cloud and is apparently identical with the
bright infrared source 2MASS 22533325+6232235 (J = 10.85).  A GMOS
spectrum (resolution 6200), obtained on Nov. 6 at the Gemini-N
telescope, shows deep and wide H_alpha and Na absorption lines on a
red continuum.  Thus, the variable appears to be a new highly
reddened FU-Ori-type object that has erupted sometime during the
past 50 years.
