Anyone else having an issue with refining predictions on Occult?? I'm on rev 4.2024.7.12.? When I try to go through the second round to refine the predictions using Horizons with the first list as an input, it pops up an error window saying:
?
Error requesting data from Horizons
Horizons will be skipped for next 20 secs
The request was aborted:? Could not create SSL/TLS secure channel.
?
This started Saturday.? I've tried rebooting, restarting Occult, etc., without success.? I guess the only thing I haven't tried yet is generating a new first list--I'll do that next.
?
Thanks.

Re: Zoom or Skype session on Occult4
Ah, summertime.... As I thought, it looks like an Occult4 session will be difficult to schedule, and I'm not wanting to spend a bunch of time trying to juggle days. Perhaps individual (or 2 at a time) sessions might be best. 4 persons have now expressed interest... Roxanne, Elizabeth, Rick and Michel (in Canada). I think I'll schedule a session with Rick & Michel soon and Roxanne and Elizabeth can coordinate among themselves for a time they can jointly be free - and let me know (they seem to have the greatest time constraints). Might be best to do semi-individual sessions anyway since I think there will be a wide degree of needs for those looking to get Occult4 running well. I'll get in touch with some folks off-list and schedule something... and maybe post the SET time here. If other can join, that will be fine.

I am also on travel with minimal Internet access.
I will try to join if available.

But actually, IF such an object were a slow moving TNO, with a l-o-n-g duration event, then you could do exposures with your Astrid of 1 to several seconds and you might reach mag 15.5. (That's why I run my Occult4 searches to mag 16 Target Stars).
[With my 14.5-inch I can get to mag 16.4 with a 1 second exposure. My 12 will get mag 15.5 in 1 second - but of course you need multiple data points in the drop].
As it's been mentioned a few times now, let's plan on having a NEUS chat session on Occult4 somewhat soon. I'll look ahead and pick a nite that will be cloudy for all. A later topic might be doing mobile observations and picking sites.

I could do Wednesday. Not sure if that helps. Rick Bria?

I am not critical to this discussion, but Tuesdays in general don't work for me as that's pub quiz night for our team.

Subject: [OccultNEUS] Zoom or Skype session on Occult4
I know some are interested in an on-line session on Occult4. I have had it in mind (and don't profess to be any expert on it, tho I use it A LOT). I'd like to schedule a session on a night that I know will be cloudy (lately nights have teased me with clearing).
It looks like this upcoming Tuesday evening (say 7pm-ish) may be cloudy. How would that work?
It seems Roxanne and Elizabeth (I think also Rick) are the ones who have voiced most interest - so I'd like for any night we pick to be ok with them.
Let me know who might be interested and if this upcoming Tuesday 7pm might work.

Re: (2173) Maresjev on 19 July
Darn, Maresjev looks to be a good event to try from Cherry Springs... but alas, I'll still be on the road some where along I80. After spending a week or so with my family, it is doubtful that making a detour northwards to camp out overnight in the truck for an occultation will go over well with the hubby. ?? I'll have to pass.? - Roxanne.

This amazing good event is about a week and a half away.? Looks like we've never managed to get any occultation data on this one.? Details:

Both Kevin and Elizabeth bring up valuable factors to consider.? I'm limited to the Naylor, ROMR and Home fixed sites - for safety more than any other concern.? Plus toss in driving home through overly bright construction zones which blows out one's night vision, I'm becoming less comfortable driving home at odd/early hours.?
One chord or two?? I would have gone for the two single chords option.? IMHO, doing so provides a data contribution across two objects vs one, confirming the orbit of each asteroid and provides collaborating data for future related occultation events. Plus, who knows when another well placed occultation event will take place and the single cord data may be the only data collected on that object for a long time.? - Roxanne

George,

That one is a full magnitude plus fainter than I've even tried (plus the low elevation)--I'm pretty doubtful I'd get anything meaningful from it.

Oc-folks:
Just quickly... Whilst making up plans for tonight I ran across a good example of why it's nice to input the Lat & Long of other's sites into Occult4. (I can explain how to do this in a later chat).
In short, in the 2 attached images you can see the sites of other NEUS observers (the "dots"), and when the path is plotted it becomes instantly obvious if the path you are considering passes by anyone else. Here you can see an event I was considering also passes near Steve C and Michel M. If set up correctly you can even access Google Earth from Occult4 and zoom in (way in!) to see how close a path actually runs.
BTW, this event is a bit too faint (maybe?) - 15.5 combined, Max dur of 1.06 sec.
Steve -- I'll be responding to your "Thoughts?" post.... when I have spare moment. Now back to tonight's planning. (Got 1 Pos last night).

Re: Multi-site Input in Occult4
Elizabeth & All:
Be glad to do an Occult4 session. But there is a LOT involved with Occult4, so for anyone interested you probably should familiarize yourself with the past posts I did... the topics are Occult 101, 201, and 301. A least a read-thru so the details in even a basic chat won't be a bit much.
BTW: For planning tonight's adventures I'm sorting thru a list of 108 Occult4-generated potential events. It becomes a research project.

The two single chords... my equipment at fixed observatory is more reliable (and safer). Trying to do remote is fraught with other issues for a woman. So, unless I have an assistant/observing buddy accompanying me, I will usually default?to what I can observe from "home". And on a few occasions, I have gotten someone to tag along.
("Home" can be observatory at campus or? backyards at parent's, daughter's, friend's...)

George covered this¡ but to add my two cents, I have used multiple dobs up to a 20 inch obsession (Westchester Amateur Astronomers) that I added digital ¡®Push To¡¯ setting circles to¡ and the best method is with a laser. You can get away with the Cheshire eyepiece for smaller scopes, but for 12¡± you¡¯re going to need a laser. We also carefully modified the mirror strap and made certain the centering pins actually centered the mirror.? Then, we changed all the polls and even changed the cage clamps. It was surprising how crude that expensive scope was made. Rick Bria?
