Re: OT-Lunar meteor impact imaging?
Hi Lawrence:
?
[To all - Lawrence has a long history of asteroid work (and has a rock named for him). He has captured several occultations and has a RunCam NE2 and VTI. He's not too far from Burlington VT].
?
Do you know... Is the Perseid meteor stream heading roughly "toward" the Earth-facing part of the Moon? Also, one comment - video monitoring could add up to MANY files with MANY Gbs of data. But it could be a worthwhile endeavor. And yes, any impact really should be video recorded by two independent video systems in order to distinguish an impact from a cosmic ray hit on the detector.

Occult Horizons Errors
Anyone else having the "Error requesting data from Horizons, Horizons will be skipped for next 20 secs.? The request was aborted:? Could not create SSL/TLS secure channel." problem this morning?? I've done all the usual, stopping and starting Occult, rebooting my laptop, etc., with no joy...

Re: 8051 Pistoria
All,
?
I provided the information that Norm wanted on this event to him, and he's forwarding it on to Dave H.? If I hear more, I'll let you know.

Re: 8051 Pistoria
Steve, Roxanne, Kai:
?
Noble attempts - Congrats. I have to wonder about those 9th mag (or brighter) Targets... I've also missed a couple bright "sure things".
?
Yes Kevin, Dave did say to let him know of essentially certain events that ended up being Misses. I let him know of one recently - never heard back (or maybe that wasn't needed?).
?
Rock on,

8051 Pistoria
All,
?
Roxanne and I deployed 4 stations for this rank 100, mag 9.5 event early this morning.? All stations recorded the star passing through center at the predicted event time.? All stations ran at 20 frames per second or higher, and look like they have high SNR.
?
Unfortunately, our preliminary analysis shows no blink on any of the 4, despite having having high (53 to 99%) probabilities <heavy sigh>...
?
Kai deployed another station between 2 of our misses, hopefully (but unlikely) he'll have a better result.

Re: (8051) Pistoria Early Monday AM
Steve:

Yes, you look to be mainly cloud-free (maybe not "fog-free") for your event (roughly at the arrow) - Best of Luck! If anything I would be driving down the Northway to Schroon Lake, NY (where the circle is) to try for your event... and I'm seeing a very good chance of clouds for 3am (see attached). For me at home it clouds-up about midnight and I have a couple low probability events I can try for in the evening here.
Again, best of luck! 9th mag events are nice.

Re: July 27UT (623)
The clouds for tonight here (Wellsboro) are still not suppose roll in until about 8 AM.? My bigger worry is fog, especially at my new site that is right by a large lake.? We will have fog, just a question of does it form before or after event time.
?
Still planning to use my observatory and 2 C-5/Astrid stations.

Re: July 27UT (623)
Even if clear skies, this was quite a 'tough' event - being so low to the horizon. Thx to all who tried. Wish it were more often that paths crossed several of us. Almost always it's just 1 observer. I'm tempted to do a drive to try for Steve's 9th mag event tonight (29th), but I'm seeing clouds moving in. ...And sadly the smoke is back this summer.

Re: July 27UT (623)
There was a bank of clouds that refused to leave the southern sky for about 24 hours¡ or more. Very strange as there was almost no movement. Almost half the sky was covered. It simply wasn¡¯t possible for me to make an attempt.
In OW desktop I can input ¡®no observation¡¯ and give a reason. I am able to cancel the station in OWC, but I can¡¯t find a place to put a reason so others will know why I canceled. That event did not show up in desktop, probably because of filters. Sorry, but I had to drop out around 15 minutes before the event. Rick Bria? |

Re: July 27UT (623)
Made the attempt.......
Hazy horizons and VERY bad seeing did me in. I do get a plot of the Target Star in the "Py's", but it's buried too much in noise. Almost, but not quite. Had to go to 1/2 sec exposures. One of the "by-far-better" video frames attached.
Was redeemed a couple hours later, from another site, with a different, very nice Pos.
I see others disappeared from OW. I think I saw clouds down toward NYC.......
Anyway, this is (one reason) we have this forum - trying to coordinate multiple chords.

(8051) Pistoria Early Monday AM
Anyone else able to look at this one?? It is a keeper for me, but it doesn't look like it gets close to anyone else.? Line is south of Pittsburgh, Wellboro, south of Ithaca, north of Montpelier.? I intend to use the home observatory plus two Astrids from here.? Early weather predicts look dicey for me, but it could go either way...
?
Monday 7/29 ~7:19 UT
Rank 100
Mag 9.5 with a 8.1 drop
Tmax 0.5 seconds
36 deg el, 199 deg az

Re: July 27UT (623)
Thanks for sending this alert. I can¡¯t do 11¡ã at Sacred Heart observatory. I can¡¯t go below 15¡ã. I will check out attempting this at the Bowman observatory, which may be able to go that low. Big things happening at the Bowman observatory that may allow me to do asteroids from there going forward. It¡¯s walking distance from my house. I¡¯ve never attempted occultations from there yet.?Rick? |

July 27UT (623)
Yup, me again....
I ran an Occult4 search and note the opportunity for a decent Multi-observer NEUS event coming up in the next few days (and I also see it on OW Desktop). Screenshots attached. The event is:
?
July 27th (623) - It seems I should have a sure-shot, but I also notice so can Rick Bria and Kevin Green. On OW I see that both Kevin and I had previously signed up. However... I note that Kevin is observing from New Haven (where he has a "0%" chance). From the observatory in Westport he could have a 100% chance. Rick has a 100% chance.
Note that, yes, this event is rather low above the SSW horizon. Possible nicely spaced 3-chord event. The asteroid has a rather oblong shape. A longer exposure is possible which will help counteract the extinction and scintillation of it being 11 degrees up. Details: ~3:22UT, Moon just rising, LOW at 11d up, Az 195d, Combined Mag 13.3, 1.8 drop, Max Dur of 4.9 sec, Above the tail of Scorpius. ?
I'm not certain of my plans yet (I have a few other event options), but..... for now... FYI.
