IMPORTANT NOTICE TO SUBSCRIBERS
     Further to IAUC 9110, the move of the undersigned and the
Central Bureau to the Department of Earth and Planetary Sciences
(EPS) at Harvard University is essentially complete -- with the
transfer of CBAT computer activity (i.e., issuance of IAUCs and
CBETs, editorial work, etc.) from the Tamkin Foundation computers
at SAO to new Tamkin Foundation computers at EPS having taken place
on August 30.  The generous gift of the Tamkin Foundation to
purchase new computers is gratefully acknowledged, together with
the continued support from Feb.-Aug. by the Minor Planet Center and
the Smithsonian Astrophysical Observatory (for donating the primary
CBAT computer to EPS and for permitting the CBAT to operate on the
MPC and SAO computers until the new computers were set up at EPS).
The EPS faculty and staff are also thanked for their tremendous
support behind the Director and the CBAT.
     With the transfer of large amounts of data from old computers
to new ones (and from one domain to another), there are inevitable
problems -- of some of which subscribers need to be aware.  With
the first issuance of CBETs/IAUCs from EPS, we notice that there
are many e-mail "bounce-backs" because our new eps.harvard.edu
e-mail address is unrecognized (many messages returned and flagged
as "spam"); subscribers will need to have their computers accept
our incoming e-mail.
     The CBAT webpages on the SAO computers have been copied over
to the new website (see URL in banner, above), although there are
many broken links that we are working hard to repair; while the
vast majority of our more-than-20000 webpages appear to be working
(including almost all of the posted Circulars and CBETs), it will
take some time to fix all the broken links.  Readers with a need
to access a webpage with a broken link should e-mail us with the
request.


COMETS C/2009 R3 AND C/2009 R4 (SOHO)
     Further to IAUC 9164, additional Kreutz sungrazers have been
found on SOHO website images.  C/2009 R3 showed a hint of a tail in
C3 images (mag about 6), while in C2 images it was quite diffuse
with a very faint tail.  C/2009 R4 was small in C3 images (mag
about 7-7.5), while it appeared in C2 images as very faint and very
diffuse.
