UKIRT NEWSLETTER : Top End
Top End
Tom Geballe
Head of UKIRT Operations
Welcome to the first UKIRT Newsletter in several years, and to the first
electronically available UKIRT Newsletter. Previously information about
UKIRT was published in the UKIRT Newsletter until 1990, in the JCMT-UKIRT
Newsletter until 1994, and in Spectrum until 1996. All of these newsletters
were hardcopy only. We plan to publish the new, electronically available
UKIRT Newsletter twice a year in the UKIRT world-wide web pages, as well
as hardcopy versions which will be available to download from UKIRT's WWW
pages. In the future, the timing of each new issue will be 1 month prior
to the PATT deadline, i.e. approximately at the beginnings of March and
September.
I am very pleased that the Upgrades Programme, now in its final year
of funding, has already resulted in significant improvements to the telescope
(e.g. see article on M87 in Ukirt Highlights) and that all of the major
new instruments required in the next few years for UKIRT, UFTI (the fast-track
1024x1024 1-2.5 micron camera), Michelle (the 7-25 micron imager/spectrometer,
and UIST (a 1-5 micron imager/spectrometer) are fully funded in the PPARC
business plan. These instruments plus CGS4, some specialist visitor instruments,
and our accessories such as IRPOL2 and one or possibly more Fabry-Perot
interferometers, will provide UKIRT with basic imaging, spectroscopic,
and polarimetric modes of high quality for years to come. We are concerned
that as of now there is no funding for more advanced instruments for the
longer term and also none for further telescope development beyond the
conclusion of the current Upgrades programme. We will continue to advocate
these, both of which are required to make UKIRT more powerful, versatile
and competitive with and complementary to 3-4m and larger telescopes.
For those of us in Hawaii, supporting the UKIRT operation has been a
strenuous challenge during the last few years, as our small (and ever changing,
it seems) staff works with engineers and scientists in the U.K. and elsewhere
to institute major improvements to the telescope, commission new and upgraded
instruments, and at the same time minimize risk to our observers and maintain
the ability to do high quality and world-beating astronomy. An example
of this risk and the price we sometimes pay immediately comes to mind.
Last evening (April 17) a failure of the CPU board in the telescope mount
computer VME crate resulted in a loss of 6.5 hours of clear weather to
UH observers. This was the first major failure of the mount computer since
it was installed in November 1995. Determining the cause of the problem
involved the effort of the telescope operator, an electrical engineer,
and several of our software staff, one key member of which was in the U.K
attending meetings on Michelle and UFTI and had to log in to JAC via modem
(as the internets both in Cambridge and Hawaii were down) to modify the
telescope control program. As more than one staff member noted, we may
have lost 6.5 hours that night, but we also gained 5. [For a more entertaining
account, see the article by Nick Rees]
There are times when many of us long for a quieter period in which we
can devote most of our hours to standard support and to consolidating and
fine-tuning the new telescope capabilities. This will not happen for a
while. For example, with two new and badly needed instruments arriving
during the next 18 months, much preparation in Hawaii is required. Thus,
during the next few years many of the UKIRT staff will continue to juggle
several critical projects in addition to supporting visiting observers.
Such it is, I suspect, for any observatory with an ambitious development
program and a committed staff. To be successful within its limited budget,
the UKIRT operation balances the effort between support and development,
making what we believe are appropriate compromises between the two. As
always, we welcome suggestions and constructive criticism about the development
of the observatory and about our support of visiting astronomers.
