Date   

NO BBAA meeting Thursday -- Picnic this month

George Reynolds
 

Reminder:  There is NO regular monthly BBAA meeting in July, since this is the month for the annual family picnic.

The Picnic is scheduled for Saturday, 17 July from 11;00 (or noon) to about 2 or 3 pm.  Please come, and if you wish, bring a side dish or dessert, and prepare to have a good time.

Sounds great!
I will be there with the Coronado PST!!

 


Saturday SUN Day today

George Reynolds
 

Today (Saturday, 6/26) is Saturday SUN Day at Elizabeth River Park from 1000 to 1300.  I'll be there.  Eddie, I haven't seen you there in a while.  Bring Riley.

The forecast looks iffy, but who believes the forecast?  They were calling for thunderstorms last night, so the Nature Bus event was postponed, but I never saw a drop of rain.  There were some clouds, though.  I hope we can see some sunspots today.

Chuck, I have fond memories of that event at the fire station.  I think of it every time I go past there down Centerville Turnpike on my way to Skywatch.

Kent, 

This Sunday is my first outreach event with the Dark Skies of Wet Mountain Valley, a Family Fun Day at a local park we are setting up solar scopes.  The club here has their own 100mm Lunt Ha scopes, my little 60mm will not be the Belle of the Ball, but they have never seen our Solar Funnel which I am taking as with me.  The park is within walking distance of our house here.

I am excited and apprehensive this group of folks are like having a dozen or so folks with you and Ted’s experience.  

Going to be fun!

Kent,

 

I have a line on a fully loaded Obsession Classic 20” F5 for $6,000 complete with ServoCat & ArgoNavis, do you know if Ray’s 20” is an F5?  I am just trying to get my mind around the size of the scope.

 

What is your 25” an F4 or F4.5?

 

This 20” F5 has an eyepiece height of 8’ (96”) at zenith, I figure my currently ladder/step stool is right at that limit.

 

The fellow just turned 70 and decided to get out of the hobby completely.  He says the scope is in nearly new condition, he rolls it out of his garage at least once a month so it has not been sitting dormant, mirrors were recoated in late 2018.

Re: Mega Comet

Thanks for posting that article, Ted.  I saw it too, and was going to post it.  That comet won't be close to Saturn until 2031.  I hope I'm still around by then.

Mega comet inbound from Oort Cloud

Kelly Kizer Whitt

June 24, 2021

Curved lines showing solar system plus arc of new mega comet by Saturn.

View full-sized image. | The newly discovered mega comet, 2014 UN271, is currently diving from the outer solar system. At its closest to our sun, it’ll come close to the orbit of the outer planet Saturn in 2031. Image via NASA.

Don’t worry, but a huge comet is headed toward our sun. Scientists found it while studying old images from 2014 to 2018 taken for the Dark Energy Survey. Two University of Pennsylvania astronomers, Pedro Bernardinelli and Gary Bernstein, spotted the object heading inward from the Oort Cloud, possibly from as far as half a light-year away. Many have been calling it a mega comet.

The object was originally designed 2014 UN271. It’s now been officially named Comet Bernardinelli-Bernstein, for its discoverers.

It’s thought to be the largest comet yet discovered, possibly as big as a dwarf planet. It’s still far away and hard to see, but the current estimate suggests its nucleus, or core, is between 62 to 230 miles (100 to 370 km) in diameter. Whoa! That’s big for a comet.

The mega comet is not coming very close to us. It’ll make its closest approach in 2031, when it’ll sail just outside of the orbit of our sun’s 6th planet, Saturn. Saturn’s orbit is some 7 times farther from the sun than Earth’s orbit. So there’s no danger to us here.

Pedro Bernardinelli announced the discovery on Twitter on June 19, 2021.

Mega comet will near Saturn by 2031

The scientists scoured the survey images and discovered 2014 UN271 moving from 29 astronomical units, or AU (1 AU is the distance between Earth and the sun), to 23 AU. At its closest approach, 2014 UN271 will come within about 10 AU to the sun, which is in the realm of Saturn. Scientists didn’t find just this mega comet, though. The full search of the six years of survey data for trans-Neptunian objects turned up more than 800 objects.

Pixelated large white dot in gray background.

The signal within the noise. This is the mega comet or dwarf planet-sized object labeled as a signal. The scientists examined old images to find 2014 UN271 as it lumbers inward toward the sun. Image via Pedro Bernardinelli.

Is 2014 UN271 the largest comet yet?

So the current estimate is that 2014 UN271 is between 62 to 230 miles (100 to 370 km) in diameter. If it turns out to be at the larger end of that range, it would be the largest Oort Cloud object yet discovered. (Comet Sarabat of 1729 is potentially the largest comet ever seen, with size estimates of 100 km, about 60 miles, in diameter. Comet Sarabat came much closer, within 3 AU of Earth, during its closest pass.) Whether 2014 UN271 takes on a traditional comet appearance and will grow a coma or a tail is yet to be seen. Scientists will have their eyes trained on the mega comet as it nears Saturn in 2031.

2014 UN271’s unusual orbit, which takes it from deep in the Oort Cloud straight in toward the sun, is hundreds of thousands of years long, the exact number yet to be determined. Despite its large size for a comet and nearness to us in 2031, astronomers do not expect the mega comet to brighten enough for us on Earth to see without powerful telescopes.

Scientists are working on a paper about the new object, which should be published in the new few months.

Bottom line: Scientists discovered a new object headed toward the inner regions of the solar system. 2014 UN271 may be the largest Oort Cloud object currently known.

Cool.

 

Apply some of that traditional BBAA dedication to outreach and a smidgen of Kent’s “Oh Wow” (best I’ve ever seen it) enthusiasm and you will indeed be the Belle of the Ball!  

 

Here in Monsoon land, we are done with outreach until fall.

Nature Bus Star Party to be rescheduled

George Reynolds
 

In case you were planning to help out with tomorrow's Nature Bus event, it is going to be rescheduled.

Due to an adverse weather forecast for tomorrow, 25 June, the Nature Bus event is being rescheduled to either 2 July or 16 July.  I will know tomorrow (6/25) which date they choose.  The sky will be darker on the 2nd, with no Moon.  Venus will be setting in the west by 9:15, and tiny Mars will follow shortly thereafter.  On the 16th, Venus will still be low in the west at 9:15, but Saturn will rise about 10pm, and the First Quarter Moon will make interesting viewing.  Sagittarius and Scorpius will be fully up by 9:15pm.  On the 2nd, Sgr and Sco will be a bit lower on the horizon.

Please be flexible to respond to either of the two dates they choose.

Subject: What Caused Betelgeuse’s Great Dimming Event

 

Hi all, a friend sent me this notice that some astronomers have come up with an explanation of Betelgeuse's Great Dimming:

The researchers found that Betelgeuse’s Great Dimming was caused by a dusty veil shading the star, which in turn was the result of a drop in temperature on its surface. Betelgeuse’s surface regularly changes as giant bubbles of gas move, shrink and swell within the star.

The scientists concluded that some time before the Great Dimming, the star ejected a large gas bubble that moved away from it. When a patch of the surface cooled down shortly after, that temperature decrease was enough for the gas to condense into solid dust. “We have directly witnessed the formation of stardust,” Dr. Montargès said.

Yeah!  I reported that is was a go at the last BBAA and SkyWatcher meeting.  I have had a RV reservation for several months.  Just waiting to register for the star party.
 
Looking forward to seeing you and everyone else there!

Re: Boardwalk Astronomy June 15 2021

I’ll echo Chuck – of all the BBAA outreach events I did, I think I miss the Boardwalk events most of all.  I wish I could get to them but it’s about a ten day round trip! And with my luck it would rain.

Last night’s Boardwalk Astronomy was successful.  The skies were clear and the sea breezes gentle. Although the crowd wasn’t as large as previous years 350-400 tourist and locals alike stopped by to peer through our telescopes. There were about a dozen telescopes. I set yo my 80mm f/8 refractor. The eyepiece is low to the ground for the comfort of kids to look at the moon. It was so nice seeing club members “in person” again and I look forward to the following months at one of the best outreach programs we offer.
