NGC 1316 Fornax A MCG-06-08-005 RA 03:22:36 Dec -37°13.4' Galaxy
|
Dunlop 548: "a rather bright, round
nebula, about 1.5' diamater, gradually condensed to the centre."
h: vB, pL, lE, vsvmbM to a nucleus 2" in
diameter; vB, vL, 4' diameter; first gradually then very suddenly very much
brighter towards the middle to a stellar nucleus.
Tom Lorenzin: "10.1M; 3.5'x 2.5' extent;
bright ellipse with very much brighter center and stellar core"
Steve Coe, observing with a 13" f/5.6,
notes: "Pretty bright, large, elongated 1.2 X 1 in PA 75, very suddenly
very much brighter in the middle with an almost stellar nucleus. There are three
levels of brightening at 135X."
AJ Crayon, using an 8" f6 Newtonain,
notes: "It is 5'x4' 10m, has a little brighter middle, NGC 1317 is 5' north
and no other objects seen in field, at 100X."
Steve Gottlieb, 17.5-inch: "vB, mL, E
3:2 SW-NE, about 2.5'x1.5'. Dominated by an intense 40"x30" core which
brightens to a non-stellar nucleus. Forms a pair with N1317 6.3' N.";
8-inch: "B, R, lE, small bright core. Forms a pair with N1317 7' N."
G. de Vaucouleurs ("Galaxies and the
Universe", Chapter 14 - Nearby Groups of Galaxies) notes that the five
brightest members of the Fornax I Group are NGC 1399, NGC 1380, NGC 1404, NGC
1326 & NGC 1350. He notes that NGC 1316 and NGC 1365 are possibly in the
foreground.
De Vaucouleurs (1956) "Survey of bright
galaxies south of -35° declination", Mem. Mount Stromlo, No. 13. On
photos taken with the 30-inch Reynolds reflector, 20-inch diaphragm: bright
inner part 4.8' x 3', faint outer regions 6' x 4.2'. Remarks: Pair with NGC 1317
at 6.3'
Two supernovae erupted in this galaxy; 1980
(12.6v), 1981 (12.7v).
Sidney van den Bergh (1961, Astronomical
Journal, Vol 66) notes that this galaxy could be a radio source. He remarks: "Dark
patches and bright knots. Similar to NGC 1275 and NGC 5128?"
10x50: "quite bright .
. . easy to find - in nice little asterism of stars. Faint but can be seen
directly. Looks like a slightly fuzzy star when viewed directly. With averted:
glow expands with brighter core. Elongated?" (suburban skies) [DC]
11x80: Observing from the
1500 metre plateau of the SAAO observing site in Sutherland, this galaxy is
easily visible in 11x80's. It is seen in a field sprinkled with many stars as a
reasonably bright nebulous patch. Suburban skies, seeing average-good. "Like
an extended 9th mag star, smaller than 1 arc min. Rating: difficult." Exurban
skies, seeing 3, transparency 3, sky darkness 4, lim.mag. at south pole 6.0
(naked eye), 10.7 (binoculars at pole) Strong SE wind. "Readily seen as a
round, 30 arcsec, non-stellar glow."[AS] |
