C-18 = ESO 358-G20. (G,N) Shows a faint ringlike structure to the north,
as well as scattered debris to the southeast and a bright "crescent
moon" feature just south of the nucleus. The Green Bank H I profile is
considerably wider than the Nancay profile (167 and 114 km s^-1^,
respectively) - due to interference? Our observations, plus 30 minutes
more, were used by Matthews et al. (1998). Within the Nancay search area
only two probable ellipticals were found of about 19 mag, without known
redshift, at an average distance of 12.5'.
ESO 358-020.-A peculiar, weak H I spectrum; the data in the
literature on this galaxy appear to be discrepant; the optical
recessional velocity of this galaxy is given as 1853 km s^-1^ by
de Vaucouleurs et al. (1991) and as 1789 km s^-1^ by da Costa et al.
(1991); Richter et al. (1994) include this object in their polar ring
galaxy study, and their Green Bank H I observations reveal a weak, but
irregular, extended H I profile with F = 1.75 Jy km s^-1^, W_20_ =
167 km s^-1^, and V_h_ = 1799 km s^-1^ (cf. van Driel et al. 1998); the
Richter et al. H I profile and/or galaxy identification may be confused
with ESO 358-025, an S0 13' away with V_h_ = 1459 km s^-1^; MG see no
evidence of this galaxy being a polar ring candidate based on its
ESO 358-020: point-like nucleus; barred; very twisted light distribution; HSB
center with three moderately bright, compact sources embedded; 2-step disk.
C-18 = ESO 358-G20. The GB 140' detects this small galaxy with
2.2 x 10^8^ M_sun_ of H I in a very asymmetric profile. The galaxy lies
near a faint, distant galaxy cluster, but NED lists no companions of
similar redshift within 10', and within the GB 140' beam one,
ESO 358-G25, at 13' away and a radial velocity of 1459 km s^-1^, which
may be responsible for some of the flux in the asymmetric line.
Unusual galaxy, type uncertain.
Very patchy chaotic center, faint dist corona. 3rd in group. Type on this
plate (I0:pec) rejected.
Overexposed center, pretty bright (r): 0.55 x 0.5, pretty faint
(R): 1.0 x 0.9. 1st in group.
