The Nova Search Committee of the AAVSO was established in the early 1930's
with
the belief that a serious stargazer can render valuable contributions to
astronomy with a
systemized visual search for and discovery of novae in the Milky Way. Those
regions in our
galaxy where novae are most likely to occur have been divided into areas
10 degrees in
declination by about 1 hour in right ascension. An observer who is interested
in searching
for novae is assigned specific areas, but once he/she has searched these, he/she
can go on to other
areas, thus encouraging a thorough coverage of the sky. In addition to searching
specific
areas, an observer can also add a "dome search" to his/her program. This is
a naked eye scan of
the whole visible sky, whose purpose is to catch a bright nova among
the brightest stars
(down to 3rd magnitude) of the constellations.
The standard equipment for the AAVSO Nova Search is a good atlas, such as
the
AAVSO Variable Star Atlas, and a pair of 7 x 50 binoculars. Following
a
standard
procedure the observer uses the atlas to prepare charts of the areas he/she is
observing as they
appear to his/her eyes. The observer uses these charts in his/her monthly searches.
At the end of each month the observer uses special report forms to report
the dome and area searches and faintest magnitudes checked to the Chairman.
Potential discoveries are verified by an experienced observer, and if
an
object is verified as "new," the AAVSO Director is contacted immediately.
Upon having
the discovery confirmed, the Director contacts the Central Bureau for Astronomical
Telegrams at the Smithsonian Astrophysical Observatory to alert
the astronomical community
via the International Astronomical Union Circular.
Observers who are interested in becoming involved in this exciting and valuable
nova search program should contact the Chairperson
Kenneth C. Beckmann. Information and assistance can be provided
to you as you begin your nova search.
