CNEOS predicts that the NEO 2019 OR1 will make a close approach on 2022-Nov-21 02:28 ± < 00:01 UT at a distance of 0.04625 AU. H=20.8 magnitude, V relative=13.38 km/sec, 'Rarity'=1 & Condition Code=1. The size is estimated to be 180-410 m so it's 16.6 magnitude according to ST4v at 0.06 AU distant on November 16.

Using MPC's orbital elements for the epoch 2022 November 16 00:00 UT, ST4v predicts that this NEO will reach a maximum brightness of 16.5 magnitude on November 17 at 21:00 EST traveling through Pegasus at 19.5"/min. The minimum distance of 0.05 AU is predicted to occur on November 21 at 21:00 EST when it will be moving through Pisces at 16.8 magnitude and 24.2"/min. Older elements used to calculate the ephemeris in September indicated that this NEO would attain a peak brightness of 16.2 magnitude as indicated in the top portion of the Object Information dialog shown below, but the newer elements indicated otherwise. Consequently this object was downgraded from 4 stars to 3. This NEO passed very close to M 31 on the evening of November 14 when the predicted magnitude was 16.8.

CNEOS predicts that the NEO 2005 LW3 will make a close approach on 2022-Nov-23 10:06 ± < 00:01 UT at a distance of 0.00762 AU. H=21.6 magnitude, V relative=13.49 km/sec, 'Rarity'=2 & Condition Code=0. The size is estimated to be 130-280 m so it's 20 magnitude according to ST4v at 0.06 AU distant on November 15.

Using MPC's orbital elements for the epoch 2022 November 13 00:00 UT, ST4v predicts that this NEO will reach a maximum brightness of 13.4 magnitude on November 23 at 19:00 EST traveling through Pegasus at 106.4"/min. The minimum distance of 1142.0k km is predicted to occur on November 23 at 05:00 EST when it will be moving through Aquarius at 14.0 magnitude and 148.3"/min.

Note that this NEO will pass within 4' of the open cluster M 73 on 2022 Nov 22 1944 EST. It will also be less than 1° from M 72 and the Saturn Nebula around that time.

If the weather cooperates, this should be an excellent chance to observe a fast moving NEO moving through the eyepiece field. Here's an ST4v Scope Finder chart for November 23 using a 13.1" Newtonian reflector showing the motion through the eyepiece: [attachment=2573]

CNEOS predicts that the newly discovered NEO 2022 VL1 will make a close approach on 2022-Nov-13 16:22 ± < 00:01 UT at a distance of 0.00303 AU. H=26.8 magnitude, V relative=8.70 km/sec, 'Rarity' = 0, Condition Code = 7.  This MP was discovered at ATLAS-MLO, Mauna Loa on 2022-11-11.

Using MPC's elements for November 13, 2022 00:00 UT, ST4v predicts that this MP will reach a peak brightness of 15.4 magnitude on November 13 at 05:00 EST when the NEO will be moving through Eridanus at 195.3"/min at 495.3k km distance. This is a southern hemisphere object. This may be too late to catch it as it fades rapidly.

Good hunting.

When doing a Designation Search for Pismis 27, in the "Search Results" box it returns Pismis 27, further down in "Data for Currently Selected Target" shows NGC 6882.
   

However, using the Designation Search tool for NGC 6882, it cannot find it. The top entry in the "Search Results" box is NGC 6885.
And looking at the Info for 6885, it shows the "Also Known As" NGC 6882.
   

In the Harold Corwin's NGC list he has 6882 and 6885 equal to each other.
   

Furthermore, if I'm not mistaken, NGC numbers are basically in RA hour order. 6882 is near the end of the hour order at 20H. And Pismis 27 is at hour 6H

So, should Pismis 27 be linked to NGC 6882 as an Alternate ID?

In the database, object Pismis 1 has only an OCL for a secondary name. It is also an NGC object, NGC 2568.

Here is a NED reference that shows it has the same coordinates as Pismis 1.
https://ned.ipac.caltech.edu/byname?objn...4&corr_z=1

Please add NGC 2568 to Pismis 1.

CNEOS predicts that this large NEO will make a close approach on 2022-Nov-12 18:45 ± < 00:01 UT at a distance of 0.10411 AU. H=15.4 magnitude, V Relative=20.15 km/sec, 'Rarity'=2 & Condition Code=0. This is a large NEO (2.2-5.0 km) with a well determined orbit.

Using MPC's elements for 2022 November 9 00:00 UT, ST4v predicts that this object will reach a peak brightness of 14.0 magnitude between November 20-24, a broad light curve. At minimum earth distance it will be in Centaurus in daylight moving at 16"/min.

Here's an Interactive Atlas chart showing the predicted path from November 12 to December 23 in Brisbane, Australia: [attachment=2567]

This is a southern hemisphere object in early November, but will become visible from the northern hemisphere later in the pass.

In ST, object NGC 281 also has an alternate name of IC 1590.

Those are actually 2 different objects.
NGC 281 is an HII region, whereas IC 1590 is an open cluster inside of 281.

Is there a way to separate these out? I presume in the next database release.

Thanks,

Hello,

I use Optolong L Extreme dual band filter which works great for the nebulas, but would like to start collecting full color stars using my lum filter for my image.   I then plan to add the full color stars into my images.

I often use the exposure calculator when planning a session for a nebula which works great.  Is there a way to have the calculator while pointing at the same object calculate just on the stars?     I see I can change expose for target object to stars but I am not sure if that takes into account the brighter starts in the FOV as I do not want to saturate them.

Or am I going about this all wrong?

Thank you for any advice

Shawn

There will be a total lunar eclipse visible on the morning of November 8, 2022 visible from most of North America. Mid-eclipse occurs at 6:01 AM EST and is visible 13° above the horizon in the west from Columbus , Ohio. The eclipse will be followed by a possible occultation of Uranus for those farther west.

CLear skies,

CNEOS predicts that the NEO 2010 XC15 will make a close approach on 2022-Dec-27 18:15 ± < 00:01 UT at a distance of 0.00516 AU. H=21.4 magnitude, V relative =10.10 km/sec, 'Rarity'=3, Condition Code=1. This is a decent sized rock, 140m-310m.

The close approach is quite a ways off, but since it's a 'Rarity'=3 event I thought that it deserved an early warning. I haven't done any calculations in ST4v yet.

Clear skies,
