1. 2004A&A...418..393S
Re:NGC 4424
NGC 4424 This galaxy has an important bar and the size of the bulge is
difficult to estimate (Kenney et al. 1996 fit the bulge-disk ratio to
between 0.2 and 0.6). It shows little traces of spiral arms. Kenney et
al. write "NGC 4424 is classified as an Sa rather than an S0 because the
outer stellar disk is not structureless". It may well be an S0/a.

Re:UGC 07561
Diffuse radio source. The NVSS flux density is probably too low.

Re:NGC 4424
NGC 4424. - On the tapered map we detect a resolved ~ 1 mJy core
plus 1.5 mJy weak low surface brightness emission to the east along the
projected disk of this candidate merger galaxy (Kenney et al. 1996).
NVSS detected a weak 4.5 mJy source. Our full-resolution data show the
core of this H II nucleus to be somewhat resolved. This is borne out of
our recent high-resolution (0.25") 8.4 GHz observations, which did not
detect NGC 4424 above a 3{sigma} limit of 0.2 mJy.
We also detect an unrelated, slightly resolved 13.3 mJy source,
2.5' to the southeast. The APM identifies it with a 20.2 mag
stellar-like object. Further properties of this background source remain
as yet unknown.

4. 1999A&AS..138..253B
Re:NGC 4424
NGC 4424 - SN 1895A: from both runs (March and May 1995) one faint and
compact patch is visible to the south-east of the SN location (at the
edge of the 5 arcsec ring); it is very red in B-V.

5. 1997A&AS..125..479J
Re:NGC 4424
NGC 4424 (SBa, I=66.8^deg^)
The galaxy is inclined at I=67^deg^. The twist inside the bar (e_max_=0.78
reached at a=8"; PA=110^deg^) does not exceed 7^deg^.

NGC 4424 is classed as a possible Sa, based
on the smooth, massive, semi-spiral outer
envelope. Short-exposure plates show evidence of
star formation in the central regions, burned out
in this reproduction, printed to show the outer
envelope. The galaxy is in the Virgo Cluster,
about 1 deg from the center of subcluster B
surrounding NGC 4472. The redshift of v_o = 323
km/s makes it a highly likely cluster member.
Galaxies within 30' include NGC 4417,
NGC 4445, NGC 4451, and a number of Virgo
Cluster dwarfs (VCC 860, 914, 926, 983, 993,
1013, 1090, 1092, 1128, and 1164).
