POSSIBLE NOVA IN TRIANGULUM AUSTRALE
     Nicholas J. Brown, Quinns Rocks, Western Australia, reports his discovery
of a possible nova (mag 9.2) on two T-Max 400 films taken on Apr. 1.73 UT with
a 135-mm f/2 camera lens; the variable is located approximately at R.A. =
16h18m47s, Decl. = -60o27'57" (equinox 2000.0; uncertainty estimated as about
10"); a precise position is urgently needed.  Brown adds that no star is
visible at this position on his film from Mar. 16.76 (limiting mag 11.5), and
nothing is visible to mag about 14 in this position on the Digitized Sky
Survey.  A catalogued star of mag 13.5-14.0 is visible to the northwest of
the variable.  Brown's visual observation of the variable on Apr. 2.74 yields
mag approximately 9.0; he also provides visual mag 10.1 on Apr. 4.695.
Following posting on the Central Bureau's unconfirmed-objects webpage, A.
Amorim, Florianopolis, Brazil, reports the following visual magnitude
estimates for the variable:  Apr. 3.158 UT, 9.3; 4.097, 9.9.  W. Liller,
Vina del Mar, Chile, reports that a Technical Pan photo (limiting mag about
11.0) taken with an 85-mm camera lens on Mar. 31.33 through an orange filter
shows a faint but definite image of the possible nova at approximate
magnitude 10.5; nothing brighter than about magnitude 11 appears on a
photo taken on Mar. 15.
