CNEOS predicts that the recently discovered NEO, 2024 CR9, will make a close approach on 2024-Jun-11 00:03±<00:01 UT at a distance of 0.04924 AU moving with V Relative=7.38 km/sec, H=19.5 magnitude, diameter 330 m - 750 m and 'Rarity'=1. There's now a 100 day observation arc, the Condition Code=4 and the Earth MOID=0.0423965 AU The solution date was 2024-May-26 05:47:18 PDT. The last solution was computed on 2024 Apr 03 so I waited to report this close approach until the orbit was better defined. The initial reported observation was by Pan-STARRS 1, Haleakala on 2024-02-15. This MP is on the MPC's Potentially Hazardous Asteroids list that SkyTools can download from the MPC.

Using MPC's orbital elements for the epoch 2024 May 26 0000 UT, ST4v predicts that 2024 CR9 will reach a peak brightness of 14.1 magnitude on 2024 June 10 at 0300 EDTwhen the NEO will be 0.05 AU distant, traveling through Sagittarius at 11.8"/minute. The close approach is predicted to occur (to the nearest hour) on 2024 June 10 at 2000 EDT when the MP is predicted to be 14.2 magnitude in Sagittarius traveling at 12.4"/minute, but in daylight and below the horizon in Columbus, Ohio. On the night of May 27-28, 2024 CR9 is predicted to be 15.3 magnitude 0.08 AU distant in Centaurus. The light curve for this object is relatively flat since the close approach distance is ~0.05 AU.

Here's the Object Info dialog for this object:     

Here's the predicted path for 2024 CR9 as seen from Columbus, Ohio from 2024 June 1-June 23. It's going to pass through an interesting region of the sky and might make for some interesting images.

Good hunting,

so I would like to add an ideal filter (as in the filter I want to observe with...like O-III or UHC, etc) to my observing list.

I started to go through the Messier List and added it to the Brief...but the Brief note didn't copy to my other lists?

would love for it to show up next to the ideal eyepiece on the list

any way to put it in there so it's permanent and comes up on every list? or what would be the best way to do this so it's right up there and not buried in a note?

Hello everyone,

I put together the AL Multiple Star Observing List that was ask in another thread. I am posting it here. Every multiple star include a couple of entries to get the whole system in the list. The brief includes one of the names for the system and the description of the pair that that entry is describing like: AB, AC, CD... In some cases the pair in the list are not in ST4 so I included the star by itself if I was able to identify it, and the data for that pair is included in the object description (as it is given in the AL Multiple Star List witch in a lot of occasions doesn't match with the ST4 data because of proper motion or orbits).

Clear skies,

Carles

EDITED: I resubmitted this list including the notes that were omitted in the original because of not checking the appropriate box.

So I have a few configurations that I use very commonly and I'm wondering how to best approach each situation.

This is all with the same telescope

1)  I use Zoom eyepieces interchangeably when I mono-view

I entered in 4 separate eyepieces (the top focal length, bottom, and two in-between). the only thing is I would assume it would never choose that eyepiece and instead choose one with a larger FOV. should I leave it as is and just know I might not capture the whole field?

2) I use binoviewers frequently - all eyepieces are 1.25" and usually narrower fields of view.

3) I use Night Vision frequently - all night vision is 40 degrees aparent field of view and there's only a handful of eyepieces involved

for both of 2 and 3 I'm thinking create another telescope?

or just create custom eyepieces that are unnamed - all say at 67 degrees field of view and let the software tell me what magnification is best, then I can figure out how to best frame it with whatever I am using that night?

or any other ideas? I would like it as simple as possible even if I lose a little bit of functionality here

So sorry to ask for help before diving into the program myself. I watched all the videos a month ago and the plan was to get this software during summer and carefully learn it...as my current work schedule is very very demanding until summer.

but just yesterday I unexpectedly got into a sold out star party in two weeks (Cherry Springs - this will be my first star party and only second time ever to a dark site).

so I **really** want to get the list generation right for this.

I have been in the hobby for 2 years but observing time has only been a few hours a week from bortle 4/5.

so my main goal is to see "showpiece" objects. my main goal is observing > learning the sky / hunting things down / seeing very very faint things (i'll circle back to all of that later). I'll be using a Nexus DSC, an alt-az mount, and a refractor. I have filters and I'll keep the eyepieces and stuff minimal. just really want to observe a lot.

can someone suggest some settings for me for list creation? I don't think i'll be able to stay up all night but I want to have a list for best objects in case say I wake up at 2am or whatever so I can get up and running right away. 

I'm guessing the sky won't be much different over 3 days so I was thinking of making just one list...like top objects at 15 minutes per observation? or should I do 10 and just take longer if I want and skip stuff? or should I do 5 minutes in case part of the sky is cloudy?

I'm hoping to make the list this weekend and print out all the charts and spiral bind it so I can study it for two weeks when I have a little downtime at lunch or whatever. so any input on settings for me would be great.

thank you for any suggestions / tips!!

CNEOS predicts that the newly discovered NEO, 2024 JY16, will make a close approach on 2024-May-15 01:10±00:02 UT at a distance of 0.00225 AU moving with V Relative=16.80 km/sec, H=24.8 magnitude, diameter 29 m - 65 m and 'Rarity'=2. There is only a 0.645 day observation arc, the Condition Code=8 and the Earth MOID=0.000655974 AU. The solution date was 2024-May-14 05:47:28 PDT. The initial reported observation was  by Catalina Sky Survey on 2024-05-13. There wasn't much warning for this one.

Using MPC's elements for the epoch 2024 May 14 0000 UT, ST4v predicts that this NEO will reach a peak brightness of 14.2 magnitude on May 14 around 2200 EDT with the NEO traveling through Hydra at 10.1"/second. Close approach (to the nearest hour) is predicted on 2024 May 14 2100 EDT with the NEO at 14.2 magnitude traveling through Sextans at 10.4"/second, but not detectable in evening twilight as seen from Columbus, Ohio. This MP might be well observed from Europe, weather permitting.

Here's the Object Info dialod for this object:     

This is another very close pass, so for the most accurate positions orbital elements should be downloaded from the HORIZONS website for a time near your planned observing time.

Good hunting,

CNEOS predicts that the newly discovered NEO, 2024 JN16 will make a close approach on 2024-May-14 09:50±00:04 UT at a distance of 0.00017 AU moving with V Relative=9.26 km/sec, H=29.6 magnitude, diameter 3.2 m - 7.1 m and 'Rarity'=1. There is a 5 day observation arc, the Condition Code=7 and the Earth MOID=4.07205E-5 AU. The solution date is 2024-May-13 07:59:00 PDT. The initial reported observation was by MARGO, Nauchnyi on 2024-05-12. The NEO was retroactively detected by Pan-STARRS 1, Haleakala on 2024 May 8 extending the observation arc.

Using MPC's orbital elements for the epoch 2024 May 13 0000 UT, ST4v predicts that this NEO will make the close approach (to the nearest hour) on 2024 May 14 0600 EDT when the NEO will be 13.4 magnitude traveling through Sagittarius at 44.8"/second in twilight as seen from Columbus, Ohio. ST4v predicts that this MP will be visible in a 13" telescope from Columbus, Ohio from May 14 0000 EDT at 16 magnitude traveling through Serpens Caput at ~65"/minute to May 14 0500 EDT at 13.5 magnitude traveling through Ophiuchus at 21.3"/second.

Here's the Object Info dialog for this MP:     

Since this MP will pass very close to earth, anyone that plans to observe this NEO should download elements from the HORIZONS website for a time near the close approach and add them to their SkyTools MP database.

Good hunting,

How is this done?

Been out for a while, now there is a change I need to turn off, that is - marking previous object as observed when selecting another object on the list. Using telescope control, if I can't identify the object, I want to go to the next object, leaving the prior object for another night.
In the same vein, if I am viewing an object and the clock runs out, it disappears from the list before I can finish and or log it

All help appreciated
