Jimmy, here's the list, please send observations of only the ones listed here.
It is same that is in the last newsletter and that was posted here a week or so
ago. Thanks for your inquiry.
We'll follow up with Ursa Major again, only this time we will stay east of the
11hour Right Ascension line of demarcation. Again, starting in the southerly
part of the constellation there's NGC3941, a bright barred galaxy with a
brighter middle. Now, moving up to the southwest parts of the bowl find the
barred spiral, M108, that is bright, large and elongated. Estimate these
number for yourself along with its position angle. Since it is 48' to the
southeast try M97, the Owl Nebula. The NGC gives this planetary nebula two
exclamation marks - why? The 3a description is for an irregular disk with very
irregular brightness. Do you see these features and where. Moving to the
bottom of the bowl on the other side is NGC4088 another elongated, barred
spiral. You should be able to see the brighter middle but what about a
distorted arm? Look about 11' to the south to see NGC4085. It could be a
challenge at 2.5'X0.8' and magnitude 12.4. You will probably appreciate our
skipping the next, rather close, object. It is M40 and will be save for some
time in the very distant future. Also skipping M101 and saving it for another
time to study its nearby galaxies we move to the early barred spiral NGC5368 at
13th mag it will also be somewhat of a challenge, but give it a try anyway. It
is faint, small and round. Now going near Alkaid, actually 2.6° is more like
it, is NGC5250, 13th mag and small. I don't get the NGC description of pretty
bright, do you? Now for some challenges above the handle of the Big Dipper.
First is NGC5007 which is 5.2' southwest from mag 6.5 circumpolar SAO 15999.
The galaxy is mag 13.3, listed a very faint and very small. In the 20' field
of view are 3 UGC galaxies UGC 8214, mag 14.4, is 12' in PA 282°, UGC 8234, mag
14.0, is 7' in PA 330° (this galaxy is listed in the SAC database as MCG
+10-19-040 ) and UGC 8237, mag 13.9, is 8' in PA 344°. Continuing above the
handle is the much easier NGC5322 at mag 10.2, an elliptical galaxy, somewhat
elongated, irregular round(?) and brighter middle. Of this selection are two
Messier objects, four Herschel 400 of which two are 110 Best NGC.

Hi AJ,
Anything in particular or just any observation east of 11 hours?
Thank you,

OK, now is the time for all good observers to submit observations from Ursa
Major east of the 11 hours of Right Ascension. So far I've got responses from
the following - Dick Harshaw, Rick Rotramel and Charlie Whiting. I thank the
for the submissions.
If you have any observations for the column please get them to me by Tuesday
so I can complete the article and forward to our illustrious editor.
Again thanks to all for participating.
