Observation Report - 15 March, 2010 - LMC part 3

Decided that since I had to cut it I would put my favorite run of areas on this last section (except Tarantula Nebula and points south that were on 1st part of this long or. Man is this awkward, this was one long OR but what a rush! Talked the whole time into my recorder nonstop, maybe that is what wore me out?

NGC 1955
Open 9.0 1.8' --- 11.3 III 3 p n BAA 05 26 04.2 -67 29 52
11:30pm 9mmNag 170x Arc of stars in center EW orientation and nebulous region is bowing around on this line's E side being the center of a wide arc open to the W. Averted vision required to see this 7' long 1/3 circle arc with outside edge to E. I did NOT report the western nebulous region that shows up as other side of a big circle if the big arc continued.

NGC 1869
Open 14.0' --- --- association BAA 05 13 53.9 -67 23 00
11:45pm 9mmNag 170x This is an area that has 1873 AND 1871 all within it. So I KNOW I saw this area. Did not make any specific observations as I must have felt it was just general field stars.

NGC 1871
Open 2.0' --- --- BAA 05 13 52.4 -67 27 09
11:45pm 9mmNag 170x 2' cluster EW mostly. About 5-6 tier1 stars. Small amount of nebuloscity.

NGC 1873
Open 3.5' --- --- BAA 05 14 01.7 -67 19 54
11:45pm 9mmNag 170x 1.5' length cluster EW mostly. Small amount of nebuloscity.

SL 125 LH 10 NGC 1763
C+N 5.2x 3.6' RID 04 56 49.0 -66 24 23
11:45pm 9mmNag 170x 5' len 2.5EL 45dPA. Few bright FStars along it's major axis

NGC 1769
C+N 2.0' E NGC 04 57 44.1 -66 27 44
11:45pm 9mmNag 170x Bright nebulous area, less obvious than 1763. with a couple stars resolvable within it. just to East of main 'bean' of 1763.

NGC 1776
Open 1.1' --- --- II NGC 04 58 39.2 -66 25 46
11:48pm 9mmNag 170x Described as a little cluster NE of 1769 and past a field star.

NGC 1773
Star 11.8 0.3 6 GSC 04 58 08.8 -66 21 53
11:48pm 9mmNag 170x Ngc1773 is just SW of this star and was described as nebulous area smaller than 1769 with couple stars.

NGC 1761
Open 1.2' --- --- BAA 04 56 34.4 -66 28 24
11:48pm 9mmNag 170x Cluster region almost as big as the bean and less nebuloscity.

NGC 1760
C+N 2.0' E NGC 04 56 35.9 -66 31 17 << best guess at coordinates
11:48pm 9mmNag 170x Just South of 1761 this object appears as a small and elongated nebulous region. [PostNote: This I think has a core of a thin EW line of stars 2' S of the 1761 cluster/nebula. Was a mysteryObject but later identified by SteveG. ]


I was very very tired and dehydrated from a long walk in the day and started feeling dizzy so decided to pack it up about 12 after a bit of wide-field looking at Milky way and so on. Very hard to pack it up with a wonderful sky and who knows what the weather would bring but had to.

What a great viewing session and what wonderful bits of sky. You've certainly made the most of your visit, Mark. I wonder if your mystery object near NGC 2018 is SL 562, looking at my atlas of the LMC. Don't have any ideas for the others.

Thanks for your reports.

Mystery Objects

Thanks for the thoughts on that object, I'll have to look up the object reference you gave, I dont have enough detail in my references for LMC obscure objects is my problem.

What I would need to figure out these mystery objects is maybe some very detailed reference because I am sure all these things have names. The one by 2018 I attach an image and I think when I said 'about 15' south' it is really about 12' south. I was moving fairly fast so my estimates are anything but 'science'.

There are so many notes to digest still that I think it will take me some time to get down to sorting out what the 'mystery objects' all were.
