1. 1994CAG1..B...0000S
Re:NGC 3780
Sc(r)II.3
PH-7634-S
April 28/29, 1979
103aO
12 min
The spiral pattern in NGC 3780 is similar
to the multiple arms in the prototype
multiple-armed galaxy M101 (Sc; Hubble Atlas,
pp. 27, 31; panel 218 here). Both galaxies are
later versions of the multiple-armed pattern of
NGC 488 (Sab; panels 115, 116, S3, S12).
The arms in NGC 3780 are thin but highly
branched. Most can be traced as individual
fragments for only about a half-rotation.
The many individual HII regions are
unresolved at the 1" level. The redshift of
NGC 3780 is v_o = 2481 km/s.
