Abstract:
We report new detailed surface U, B, V, R, and I photometry of 81
stellar structures in the disk of the barred galaxy NGC 3367. The
images show many different structures, indicating that star formation
is going on in most parts of the disk. NGC 3367 is known to have a
very high concentration of molecular gas distribution in the central
regions of the galaxy and bipolar synchrotron emission from the
nucleus, with two lobes (at 6kpc) forming a triple structure similar
to a radio galaxy. We have determined the U, B, V, R, and I magnitudes
and U-B, B-V, U-V, and V-I colors for the central region
(nucleus), a region which includes supernova 2003 AA, and 79 star
associations throughout NGC 3367.
Description:
The observations were carried out using the 84cm optical telescope at
the Observatorio Astronomico Nacional at San Pedro Martir, Baja
California, Mexico on 2005 March 8 and 9.

Note (1): The position of star 3 is RA=08:48:37.5, DE=+11:57:23.4 (B1950);
as a comparison, the position and magnitude reported in the USNO-B
star catalog (Monet et al., 2003, Cat. I/284), for a star probably
associated with star 3, is RA=08:48:37.95, DEB=+11:57:57.9 (B1950)
(magB1=13.98, magB2=13.54).

Note (1): Notes as follows:
b = Centermost region (nucleus + part of the bulge) of the galaxy
c = Northeast region of the stellar bar
d = Southwest region of the stellar bar
e = Position of the peak which includes supernova 2003AA Type Ia
(Swift et al. 2003IAUC.8063....1S 2003IAUC.8063....1S;
Filippenko & Chornock 2003IAUC.8084....4F 2003IAUC.8084....4F)
f = Dim star within NGC 3367
g = Bright star southwest in the field of NGC 3367; this star was
taken as a test star in order to estimate the uncertainties when
obtaining its magnitudes with different aperture radii
h = Small galaxy with weak surface brightness to the south-southwest
in the field of NGC 3367
i = Bright star south-southwest in the field of NGC 3367; this star
was taken as a test star in order to estimate the uncertainties
when obtaining its magnitudes with different aperture radii
