x185 27' TF

NGC 4177 Galaxy *
RA: 12h 12 41.2s Dec: -14 00' 52"
Mag: 14.0 S.B.: --- B-V: --- Size: 1.6'x1.1' Class: SA(rs)c pec:
P.A.: 69 Inclination: --- R.V.: +4083 Source: RC3 *

This is a slightly curious object that is diffuse and quite low SB. It appears as a somewhat flattened oval in about 1.5' x 1' in PA 90 it from slightly to centre but seems to have a weak bar running through it in the same PA. No *s immediately associated.

These three are basically in a line from NW to SE, -14, -22, -48 by 20 and then 10'. Starting with -22 in the centre, it is a small elong oval eg in about PA 15, about 1.25' x 30" LSB outer halo with indistinct edges growing slightly to centre where there is a small, round core zone about 10" diam which in turn brightens to centre but no real nucleus.

-14 is to the W of -22 and nr a short line of 4-5 very faint 8s. Small round eg about 50" diameter. No *s immediately associated rising broadly and slightly to centre where there seems to be a very small slightly brighter stellaring that is only weakly brighter than the halo.

-48 is about 3' N of a mag 12 * as a tiny, almost stellar spot of LSB haze, no more than 15" diameter.

This is a very diffuse quite LSB but sizable eg approaching 2' diameter, round has a very very faint * (mag 16) embedded on the edge of the halo to the SE of the nucleus. Grows broadly and weakly and broadly to centre without any zones or nucleus. The ESO eg pair lies 25' SW.

Both of these are very small or tiny and very faint LSB egs. The N most is -61 which is a small 15" dia spot of gossamer rising slightly to centre.

-59 is a very elong little streak of gossamer about 30" x 5" in PA 90 of consistent SB. Both are very faint.

Of this group, IC 4249 is the brightest and it appears to almost grow out of the side of a mag 11 * in PA 315. A small spindle about 20" x 5" of very low SB. NE by 6' is -53

-53 is a very distant eg, note the RV. Elong in PA 45, a very LSB small oval about 40" x 10" growing broadly and slightly to centre without nucleus.

MCG -5-32-27 is about 10' eastward as a very small spot of very LSB mist with no zones and slight brightening to centre. Seems about 20" diameter and round.

Of these two the IC eg is the brightest and most easily seen. IC 4270 is a small round eg no more than 40" diameter. No *s immediately associated. Grows broadly and slightly to centre azonally without nucleus. ESO 509-38 is 6' SE.

ESO 509-38 is smaller and fainter and of lower SB about. Weakly elong in PA 45 lens shaped 20" x 5" rising hardly at all to centre with what appears to be a mag 16 * nr centre of maybe just to the NW of centre.

Class: IB(s)m P.A.: 75 Inclination: --- R.V.: +477 Source: RC3

On the DSS this is a strange looking lumpy thing to the east by 3-4' from a mag 9 *. There are also two mag 13 * to the E and SSE of the eg just outside the edge of the halo. Pretty smooth looking halo with ill-defined edges 1.75' diameter growing broadly and weakly to the centre azonally and without nucleus. Possesses reasonable though lowish SB.

And that was the end for that part of the sky. With Leo now riding high on the meridian and the sky still 80% clear (most cloud was in the south) it was time to see some in The Lion. The SQM reading at 11pm was 21.69 = ZLM +6.48.

This is a fairly sizable eg pointed at from the SW by 9th and 10th magnitude *s several arc-mis away. Pertty large and of LSB, 3' x 1.5' in about PA 15, very indistinct edges, very LSB growing broadly and weakly to centre. There seems to be a substantial 1' x 30" weakly brighter bar or core cone in the same PA not growing further to centre. An extremely faint extension off the N end to the E about 20" long is 3447A.

About 7' NE to the N of a couple of mag 12.5 *s is another very, very faint spot of mist about 15" diameter with no structure visible -- this is PGC 32713. Note the R.V -- new distance record holder about 1.2 billion ly distant!! This is the brightest eg in AGC 1126

This eg makes a key-stone type asterism with 3 13th mag *s to the N, NW and W a couple of arc-mins away. A small, round reasonable SB eg about 1.25' diameter, round growing broadly and slightly to centre where there is a very small weakly brighter zone, but no real nucleus.

This is a really peculiar object as it appears on the DSS, but no so much of that is visible in the ep. In a very blank field. There are 2 mag 11.5 *s on the field-stop to the NW and SW but little else brighter than mag 12.5. Appears to be elong in PA 30, 1.75' x 10". The nucleus is off-set to the SE flank slightly within the halo, but centred tip-to-tip. A longish streak of LSB and indistinct tips growing weakly to centre and at centre is an ill-defined 5-10" spot weakly brighter than the halo

Note the R.V! This eg is found in the midst of a bunch of mag 10 to 12.5 *s that form a "V" pointing N. It is at the southern extremity. Not quite *ar it is very tiny, 15-20" diameter growing evenly and moderately to centre where there is a very small spot type core that is only weakly brighter than the surrounding halo.

This eg is found about 6' NE of a mag 9 and possesses reasonable SB. Small oval halo in about PA 0, no more than 1.25" x 30" growing broadly and mod to the centre without any apparent zones or nucleus.

-37 is a very small, quite faint eg about 20" diameter, round and growing evenly and slightly to centre where there seems to be a very tiny sub-stellar spot in the centre. -39 is to the N by about 3' and pointed at by a couple of mag 14.5 *s that are east of -37. It is very very tiny, almost *ar spot about 5-10" diameter and very very faint. Almost looks *ar -- like a mag 16 * with a bit of surrounding gossamer.

This eg appears to the N of a mag 13 * by about 3'. It is an oval shaped halo 1' x 20" in about PA 30 growing broadly and slightly to centre with no zones but an extremely faint stellaring occasionally visible nr centre.
