There are very subtle
observations that have profound implications available if you
know where to look. One of these somewhat advanced
observations was available tonight. If you look hard at some
craters you will see that they are not really circular. This
can be hard to notice due to the spherical shape of the
surface. Close examination of the craters Ptolemaeus,
Alphonsus, Albategnius shows they are really hexagonal in
shape. A good terrestrial example is Meteor Crater in Arizona.
All of these craters are not round at all. Incoming objects
that impact planets or the moon expend their energy in non
homogeneous crust. Previous fractures, faults, and weaknesses
in the crust will control the way material is excavated out of
the existing target rock during crater formation. These
preexisting weaknesses alters the circular nature of the
crater wall resulting in a deviation from what would be
normally a circular crater wall in homogeneous crust. Hence
the above mentioned crater hexagonal outlines. You can observe
this in a telescope and or look up a picture of meteor crater
in Arizona on the web.
On the moon, many craters
have straight sides that seem to orient in common directions.
Some early lunar observers, including mining geologists, who
knew about lineament analysis saw this. They posited that the
straight crater walls were controlled by preexisting deep
seated fractures in the lunar crust far below the present
surface. Look at these craters and see what you think.

James River Star Party results?
Stu Beaber
George...or anyone who went to the subject SP, how was it?
I was loaded and planned to go a year or 2 ago and the night before, a tornado went thru that area and took out all power to the state park The SP was canceled. There fore I never got to go. I know the weather was good but was it a star party or more of a out reach event? Stu |

Thank you BBAA Members
I wanted to forward the Thank You note that we received for our participation with IOMN at the Barry Art Museum. Thank you for helping make the 3 day event a success.
Dear Museum of the Moon Partners,
I am delighted to reach out with the attached final report of the impact of our efforts together to produce the Museum of the Moon festival at Old Dominion University. Thanks to each of you, we were able to attract 12,500 people to 43rd street to learn about regional research in the Environmental Corridor, stargaze through telescopes, watch live performances under the moon and collectively bask in the immersive ambience and take a photo. Over 2,550 attendees came into the Barry Art Museum to see our exhibitions and participate in hands on activities with our partners at NASA. Paid and organic media reach another estimated 136.4 M people. The sculpture was an object of wonder and united us all after a challenging year.
It was a stellar experience- with music, food, drinks, merriment and interdisciplinary conversations- all despite having to take the artwork down on Saturday due to high winds. From all of us here at the Barry Art Museum, we appreciate your energy in making this a successful and memorable event for our entire community. We look forward with great anticipation what we can launch together next year!
Onward,
Charlotte Potter Kasic |

Re: Astronomical League Log-in?
Jim Tallman <jctallman@...>
Brian, you do not need a login for the astronomical league site. All you need to do is go to the program you want read the instructions, and in most cases there's an email address there that you can contact the sponsor of that award. Most of the time they will respond.

Astronomical League Log-in?
I have been working on several programs through the Astronomical League and realized that I do not have a working log-in to the site. Is this something I need to apply and pay for, or is it included with my night sky network account?
I've really started to pour a good amount of time into these programs and would really like to know/understand how to get credit for completing them. Thank you. |

Re: JRSPSP - Ready to go!
Good luck to you all. As I used to tell everybody coming to the East Coast Star party never rely on the weather forecast. Even if it’s partly cloudy you’ll get a good taste of a dark sky. I think one of the darkest skies I’ve ever seen was at Montebello State Park in the Blue Ridge. One of these days I wanna go back again.

Thanks George. I was watching that

Please note that there will be NO scheduled Nightwatch date in December (check the Chippoles Special Use Permit for 2021). There is something else going on there that month, so we will not have our monthly Nightwatch session in December. December this year was a bad month for scheduling, due to unfavorable Moon phases on the weekends. SO, on the New Moon weekend December 4 we will have Skywatch at Northwest River Park. That means we will be having back-to-back Skywatch Saturdays, November 27 and December 4. Our annual anniversary luncheon will be the following Saturday 11 December, SUN Day will be 18 December, and Christmas Day will be Saturday, 25 December.
