The Arecibo RFI Environment:
The Arecibo monitoring system continues its round-the-clock
operation for a hill-top near the optical lab. This page
shows the present environment for RFI at Arecibo.

The Northern VLA Sky Survey (NVSS):
This is a radio continuum survey covering the sky north of -40 deg declination
The survey has a great postage stamp server located at
http://www.cv.nrao.edu/NVSS/postage.html
The NASA/IPAC Extragalactic Data Base (NED):
This is built around a master list of extragalactic objects for which
cross-identifications of names have been established, accurate
positions and redshifts entered to the extent possible, and some basic data c
collected.
Bibliographic references relevant to individual objects have been compiled, a
nd abstracts
of extragalactic interest are kept on line. Detailed and
referenced photometry, position, and redshift data, have been taken from large
e compilations
and from the literature. NED's data and references are
being continually updated, with revised versions being put on-line every 2-3
months.
This is located at http://nedwww.ipac.caltech.edu
SIMBAD:
The SIMBAD astronomical database, created and maintained by the
CDS, Strasbourg, brings together basic data, cross-identifications,
observational measurements, and bibliography, for celestial objects
outside the solar system: stars, galaxies, and nonstellar objects within our
galaxy,
or in external galaxies.
SIMBAD is located at http://cdsweb.u-strasbg.fr/Simbad.html
The STScI Digital Sky Survey (DPOSS):
The Digitized Sky Survey comprises a set of all-sky photographic surveys in E
, V, J, R, and N bands conducted with the Palomar and UK Schmidt telescopes.
The images are available at

SkyView:
SkyView is a Virtual Observatory on the Net generating images of any part of
the sky at wavelengths in all regimes from Radio to Gamma-Ray.
