Request to Dr. Neil Degrasse Tyson at VAAS Conference October 21
Today, I followed through on my idea to get Dr. Tyson as a speaker. I accessed Dr. Neil Degrasse Tyson’s email request speaker page, today and requested he attend our VAAS Conference on October 21st. He has a speaking engagement in Jacksonville Fla on the 17th, already, so perhaps we have a chance in getting him at our conference.
Think of the possibilities if we get him to speak. We’ll need the TCC Auditorium/Theater in the ATC Building!
Wishful thinking, … but if you don’t ask, you don’t get him!
Sincerely hopeful, Jeff Goldstein BBAA Secretary

Re: 2017 Solar Eclipse Award Spreadsheet
I don't know if I'm just being hopeful, or if I've been staring at too many images, but the third image the AL site put a link to (#3 by Corrie Ann Delgado) seems to have two other objects in it. One is to the right of the eclipse and easily visible, but I'm not sure if it's a planet or a star. The other is very faint, small and bluish, and located a ways to the left of Regulus. Are any of those of use as "reference" stars?

Thanks. In the writeup they offer this link for images:
It took some scanning to actually find them again. It was in the beginning of the website, and not under the Resources and Links section.
Thanks everyone for sharing your Eclipse attempts and successes. I have laughed that hard for some time after hearing Kenny's story. Puts things into perspective doesn't it? Bob, thanks for driving and the company.

Re: 2017 Solar Eclipse Award Spreadsheet
Bird,
Looking closely at the photos in this link, the images only show the eclipse with Regulus. I don’t think there are many images with a 7th magnitude star close aboard… not that I’ve found on the internet.
My calculations are with Rob Ratkowski’s image (link #1). Best image with smallest dot for Regulus. Still only a 0.6 arcsecond deflection! Fat chance of resolving this with this kind of tolerance!
Thank you for the info and link.
Sincerely,
Jeff G.

The sun today and Asteroid Florence
There is some solar activity in H-alpha today, but not too much. Look fast in white light scopes at those large sunspots because they're drifting to the limb
Asteroid Florence is dimming and moving slower across the sky so if you want to see it you'd best try tonight as it'll be high in the sky in Cygnus. I saw it last night. As with last night it's near NGC 6826, The Blinking Planetary so that's a fun stepping stone to locating it. Kent Blackwell

2017 Solar Eclipse Award Spreadsheet
To all BBAA Club members:
I have prepared a spreadsheet to share only among BBAA club members that are attempting to earn the Astronomical League’s award. Please give me feedback before I submit. I’m sharing this information in hopes that other members in the club will try for the Level 3 award.
I’m attaching my Excel 97-2003 Spreadsheet for compatibility to other platforms. See the bottom of this email to download it.
Here’s the website with the details for the award: https://www.astroleague.org/content/solar-eclipse-2017-special-observing-award
Sincerely,

Massive X-Class Solar Flare from Sunspot AR2673
This is from Space Weather.com:
"X-CLASS SOLAR FLARE: On Sept. 6, 2017, at 12:02UT, active sunspot AR2673 unleashed an X9.3-class solar flare--the strongest solar flare in more than a decade. The explosion also hurled a CME into space, and possibly toward Earth. Analysis of the event is still underway. Visit Spaceweather.com for updates and more information about the historical context of today's remarkable flare."
X-Class - X9 (and then some) no less! It's a big one. This could cause all sorts of havoc if it hits the planet. (There is no upper limit to X-Class flares, so where your A-Class would cross from A9.9 to a B-Class after that, your X-Class can go as high as needed, even as high as X42 or more... which would pretty much kill every electrical grid on the planet of that sort of CME hit us head on.)

Eclipse Planning
Roy Diffrient
After reading Chuck’s saga, I thought I might provide some alternative
thoughts and maybe a happier tale.
Our first decision for the eclipse was to make the trip a vacation with
several worthwhile destinations. This so that if the eclipse was clouded
out, the entire trip would not be a total bust. So we planned to be in
Tennessee for the eclipse, with subsequent visits to Nashville, Huntsville AL,
Gatlinburg and the Smoky Mountains, amounting to a full week, and all within a
radius of about 150 miles there. It’s generally pretty rural there of
course, so I hoped that would help avoid massive crowds. The Wife
Acceptance Factor was also high, since we would be seeing and doing lots of
stuff she was interested in and had never done before.
I made our first hotel reservation for the path of totality on July 9,
2017. That’s barely 6 weeks prior to the event. To do that so late,
I reasoned that we did not need to be there for the weekend, which was, of
course, pretty much sold-out everywhere in totality-land by then. So I
made our eclipse-location hotel reservation for only the night of the eclipse,
Monday 8/21.
Obviously, this would not be good for those who wanted a weekend eclipse
party, or who needed a lot of setup time and on-site location planning.
But we were traveling light and alone. This was our first total solar
eclipse, and we just wanted the experience. Our eclipse equipment
consisted of two lawn chairs, cardboard eclipse glasses, one $29 pair of eclipse
binos, and a kitchen colander. My few photos were taken hand-held with my
super-zoom point-n-shoot – just a nice memento.
We met some friendly amateur astronomers at a grassy patch of land between
three hotels, and had a memorable, amazing, cloud-free eclipse. I had
scouted out this location using Google Maps, and it turned out well. But I
was prepared to relocate if necessary – lots of open land in small-town
Cookeville TN. So we sat in the shade of some small trees while the
eclipse progressed, with the hotel lobby (and bathroom) less than 100 yards
away.
We made the trip down to Knoxville TN via I 81 on Sunday 8/20/17. I
was a little concerned about this initial trip, but it turned out fairly well –
back-ups for accidents delayed us an extra hour, so 9 hours instead of 8.
Knoxville was slightly out of totality, so reservations there were easily
available for that Sunday. The relatively short drive from Knoxville to
Cookeville TN on Monday morning, eclipse day, was also easy. As soon as we
got away from Knoxville the traffic was light.
And of course, after the eclipse, plenty of hotel rooms were available, and
there was light traffic for our trip to Nashville on Tuesday 8/22. I had
one reservation cancelled – one hotel near Nashville apparently closed for some
reason, but they notified me in time to make another reservation, as they should
have.
In short, it all worked out great and we’re very glad we did it. By a
little alternative thinking and planning to be somewhere other than the worst
choke points, we seem to have avoided some frustrations. Of course, the
good weather we had was pure luck. But in 2024, assuming we’re still able,
I will try to start serious planning more than 6 weeks ahead.
Roy
