Meeting:

VP Programs, Mark Moffatt, welcomed all to our meeting and recognized the ACA officers that were present.  Mark then introduced the evening’s main speaker Ron Ferris.

Ron’s program was on Various Solar Cycles, with brief review of the major different cycles of our Sun’s ongoing dynamic activity. Highlights included

 

1.    Solar Rotation:              25.38 days at equator, 36 days at the poles

2.    Sun Spots:  Lifespan:  1 hour to several months

                      Number:   11/22 Year minimum/maximum cycle

                                        Cycle 24 (current) peaked in 2013   (weak)

                                        Cycle 25 expected to be weaker still

                      Maunder Cycle:  ~400 years           

                                                   Sun nearly spotless in 1645 lasting 70 yrs.

   Trending downward since 1980s

                                                   New Minimum predicted for 2030

3.    Solar Brightness:  Tied to sunspot activity

                                    Areas around sunspots brighten up causing sun to shine a bit brighter,

more than compensating for the dark sunspot areas.

4.    Solar Wind Speed:  Correlated to solar sunspot activity:

Highest at solar maximum, Lowest at solar minimum

5.    Solar Prominences & Filaments:  Globally similar in profile to sunspot cycles but different in detail

6.    Solar Spicules:         are small jets of gas concentrated on boundaries of granulation cells,

on photosphere, caused by convection currents of plasma within the sun.

Life-cycle: 5 to 10 minutes each

 

After the evening’s presentation, Stan Howard, VP Observing, challenged the audience and presented “Themed” door prizes for answers to the following questions:

·         When did the Space Age begin in the mind of the public?  Roswell, NM, July 1947 (before October 1947 when Chuck Yeager broke the sound barrier).

Stan and Tedda gave a hint, by wearing their Martian Terraformer Psionic Wave-blocking Headgear

·         Name four Trans-Neptunian objects (TNOs): Pluto, Eris, Makemake, Sedna. OR10, Quaoar, and others.  See a list at NMR

·         Name four of the moon’s12 major Mare: M. Frigoris, Crisium, Serenitatis, Tranquilitatis, Fecunditatis, Nectaris, Vaporum, Imbrium, Insularum, Nubium, Humorum. Oceanus Procellarum.

Winners received a “UFO” squash, and included Suzanne H, Joshua C., Richard C, and Margaret T.

 

Tedda H., Secretary, asked John W. to help with the  Installation of  the New ACA Officers for 2017-18.  We were unable to do this last month as planned.  All officers, except Treasurer were present:  Kenneth Beard, President, Stan Howard, VP Observing, Mark Moffatt, VP Programs, Tedda Howard, Secretary.  They promised to take responsibility to attend and do their best for the club and its members. We hope to install our new treasurer at the July 22 Star Gaze. 

 

ACA President, Kenneth Beard, welcomed all to our meeting, and introduced Joshua C., interested to join our club.

Kenneth announced that this year’s ACA Awards would be presented by last year’s officers. 

 

·         As we had no Secretary last year, Tedda H. (Web Editor) presented the Attendance/Enthusiasm Award to Margaret Travis, who has been an attentive member and enthusiastic observer, even lying on the cold ground to learn about constellations.

·         Mark M. presented the Program Award to Gary Senn, in absentia, for his program on the upcoming Eclipse activities in the Aiken area.

·         Stan H. presented the Observing Award to Stephen Miller for his beautiful photos of the moon, Jupiter, and other heavenly bodies, and his ability to show us these out on the field on his camera monitor.

·         Kenneth presented the President’s Award to John White for his long time service to the club.

Kenneth announced that the last President’s Award plaque had been filled up and a new plaque started.  John White was the first person to go on the new ACA President’s Award plaque, as well as the only person to have his name on all three President’s Award plaques.

 

The ACA meeting concluded @ 8:05pm, and the club adjourned to the break room for “NASA Firsts” themed snacks.  Many thanks to all who brought delicious hotdogs, chips, cakes, brownies, Tang, and other goodies.

The Astronomy Club of Augusta met for their monthly Star Gaze on July 22, Saturday at NMR-DSO. Attendance was twenty members with one visitor joining, and four guests, 25 total.

 

The Officer’s had a meeting at 5PM.  We discussed several items.  Cathy arrived at 5:50 and told us about new forms she made for the Treasurer’s Reports.  She told us that she would not be able to provide New Member information for a week after receipt or meetings. 

Tedda finally  had to leave at 6:20, so the officers' meeting officers’meeting came to an end. No arrangements were made to install Cathy as Treasurer. 


As scheduled, members started arriving for our 6-8PM  Eclipse station poster preparation.  Suzanne brought her Cat in the Hat Space story, and Stephanie, Margaret, and Tedda helped her put them in plastic and in order.  We went outside to staple the enlarged pages to a luan board, which Stan just finished cutting out with StephanR.’s help.  They cut out several other luan boards to size.  RickS. Came out of “nowhere” with great enthusiasm to help, and held down sheets and helped Tedda staple the  Leo the Lion story poster.  Lauren brought her Safety Solar Glass poster sheets.  We all agreed that it could be made larger for people to see from a distance.  She and Stephanie, and Margaret reviewed MarkM’s poster on Partial Eclipses viewed through tree leaves, and agreed that  it was good, but much too small for anyone to read.  They recommended that he enlarge the print and place the photos on separate pages.  He agreed, said he would email the pages and size luan needed.  We had some good conversation, and AJ and others had fun feeding Freddy pretzels.

 

We enjoyed some snacks: veggies & onion dip, cantaloupe, and Margaret’s beanie weenies.  Thanks so much.

 

At 8:50 it was time to walk up the hill and look for Mercury near the setting sun.  We had a good time doing it, including AJ and Wade, but never did see Mercury on this pleasant but somewhat clouded night. 

Meanwhile, Pat tried to help Kenneth with his scope, but with some missing parts, the solution has been delayed.  Chris’ dad, NevinS helped him and his older brother set up their scope, and spent good time observing during the evening.  RickS was delighted to observe and discuss astrophotography with SteveM.  John had an opportunity to review some northern stars with his daughter and grands.  We all saw Jupiter, Saturn, and the Summer Triangle.  Stan focused on double star, Albireo, Andromeda, and others. 

The viewing turned out much better than expected, and Steve got some great photos.

Kenneth and Tedda started at 7:30 from NMR, and drove up to Lexington to get our 10 ACA Eclipse Posters, meet with the Museum Director, and take our posters around town to get them posted. We stopped for directions once, and made contact with the manager of a rather large business, who was delighted to tell his employees about our Eclipse plans. We arrived just before 9AM and were thrilled with the results of Adela’s poster prep! Pine Press Printing did a great job, and we appreciate the funds that the Museum was able to put toward them.

LCM Director JR Fennell graciously posted the first poster, and took us on a tour of the buildings and field/mostly nice lawn so that we could plan our station locations. He also agreed to make a blow up map so that we could post it after people register on the morning of the Eclipse. Kenneth took photos, which are a big help in negotiating our way around. It will be great as there are many places with shade, but with sun close by.

We dropped off posters at the Bi-Lo across the street, Lexington High School for their registration day +, at the Post Office, the Bank, and several other places. Some businesses could not post due to corporate policy. Finally, we stopped by Jimmy John’s Sandwiches. When Tedda called them beforehand, they offered to sponsor our free lunches on Eclipse Day: with 36 subs, pickles, and cookies. We were glad to confirm this, and meet the manager that will be there that day. They asked us to pick up the order, so we need a volunteer to drive over there at ~11AM on Eclipse day. They posted one of the many 8.5x11” posters that Kenneth ran off. When leaving we needed to ask for some directions, and Tedda ended up next door at the ice cream parlor. They were a delightful Armenian couple, and had the most delicious ice cream. Kenneth treated Tedda, and they placed a BIG poster in their window! We drove down the Batesburg-Leesville and placed a poster at Shealy’s BBQ, and that was it for our day.

Later Aiken County Library was pleased to prominently place the last of our big 2x3’ posters. We have saved back two posters: one to put out on Hwy 378 where the public will enter the Museum grounds, and we will have our registration table. We kept one medium poster to put on the back of the truck when we head up to Lexington.
