The other username Palomar7 she used for a bit but felt it was still to masculine due to a few members that rubbered her the wrong way and did not come back after that.

I would like to express my deep appreciation that both GW Johnson and tahanson43206 virtually attended Dr. Bell's excellent presentation. The attendance was below normal--probably due to a PBR (Professional Bull Riders) event at the local arena and a gun show in town. Our core group of regulars was there, tho'. The weather was also the first shirt-sleeve warm day this Spring.

Wyoming is a bit chillier than central Texas. We've reached 90 F once already, and are headed there again this week.

It's been over a quarter century, but my experience in Minnesota said that those folks think it is swimming weather, once the ice pack breaks up on the lakes.

In Minnesota they wear flip flops and shorts out in the snow!

GW Johnson · 2024-04-16 14:37:39

Yes, I know. I have seen it.

I was there 2nd half of winter 95-96 and for winter 96-97, which were both 100-year record-setting winters for cold and snow, even by Minnesota standards. That was a real education for a Texas flatland boy.

We moved in between Christmas 95 and New Year 96, during a local heat wave. It was 17 F. Then it dropped below 0 and stayed there. From New Years' Day to mid-March, there was not one single day when it was not at least 20 below 0 F for the morning low, and never got above 0 F for the afternoon high.

That stretch finally broke mid-March, when the wind died and the sun came out. It felt warm. We were all running around the snowbanks outside in short sleeves, myself included. Because it felt warm. The actual temperature turned out to be positive 3 F.

The worst day was Feb 2, 1996, in Mankato, MN. It had been -30 F all night with 40-knot winds. It was -31 F in Mankato that morning, with an afternoon high of -14 F. Up in the arrowhead region near the Canadian border, it was -61 F (not a wind chill). 200 miles further NW at Winnipeg, it was -84 F, again not a wind chill.

The next winter was not quite as cold, but even snowier. About 10 miles west of me, the snowpack was 20-30 feet deep all the way to Montana. I thought my thermometer was broken, because it said -10 F every morning from November to March. I found out it was not broken when we moved back to Texas, and it went to 104 F. I had 2-to-5 feet of snow in my yard all winter long. The meltdown was only 2 weeks long, in mid-April, which caused massive flooding in multiple states.

tahanson43206 · 2024-04-19 17:35:21

For RGClark re #31 .... thanks for asking that question! The session was definitely recorded!

However, there is work that needs to be done to move a Zoom recording to YouTube.

Hopefully RGClark will inquire and report back on the disposition of that recording.

(th)

Oldfart1939 · 2024-04-21 14:04:38

I believe that in the future, all talks which are recorded will be available through the Yellowstone Valley Astronomy Association Facebook page.

Oldfart1939 · 2024-05-02 14:25:49

Here's a "heads up" notice re: Yellowstone Valley Astronomical Association meeting and my upcoming presentation on Cosmochemistry:
This coming Saturday, 4 May 2024 at 3:00 PM MDT. All are invited and I'll post the Zoom information as soon as I have it from our IT specialist.

tahanson43206 · 2024-05-03 19:58:20

For Oldfart1939...

You're cutting things a bit close here!

It would be helpful to have the Zoom address up on the board already.

I'm going to try to encourage SpaceNut to listen in.

He has a very old computer and may not have sound enabled, but we have time for him to set up to hear your talk.

Also, in your announcement, please use Time.is to provide the correct time zones for your NewMars audience.

You can use UTC for our European members, New York for SpaceNut, and Houston time for our Texas members.

(th)

Oldfart1939 · 2024-05-03 22:39:39

Our time zone is Mountain Daylight Time. Same as Denver.
I'll try to get this Zoom address posted in the morning after contacting the IT specialist.

tahanson43206 · 2024-05-04 06:52:39

For all ...

time.is/utc can be set to show the time in cities of interest...

The city of interest in the case of today's presentation by Oldfart1939 is Denver.

To add Denver to your display of cities of interest, enter Denver into the Search window. The time in Denver will be shown.

Then add Denver to your favorite locations list.

The time.is application will save your preferences so the next time you open it the city of Denver will be present.

As a reminder, if anyone is thinking of attending the presentation today, if you are not familiar with Zoom, you can practice using the NewMars Zoom account at the topic for Zoom Collaboration. When Oldfart1939 provides the link later today, just click on that and the Zoom program will connect. You do not need a camera or a microphone. All you need is a computer monitor and a sound system, so you can watch and listen.

There will be a Chat window in case you have a question for Oldfart1939 after the presentation.

For Oldfart1939...

This post arrives on NewMars as the meeting is underway. Shortly you will be introduced as the featured speaker. While we (in NewMars) cannot experience the moment live, we can anticipate the YouTube video of your presentation. Best wishes for an ample audience, and for great questions for you to tackle. Those will live on in the YouTube video, so please encourage your audience to come up with good ones!

In anticipation of the forthcoming video, I'll change the topic title to reflect it.

Thanks again for telling us of this homage you have prepared for Dr. Urey!

Oldfart1939 · 2024-05-04 19:17:41

Our Sec-Treas is also the computer geek; this will be available through the website: YVAAMT.com
We are now routinely recording all presentations. Sadly, the turnout was pretty poor due to some nice weather allowing folks to get over the Winter "Cabin Fever" syndrome.

The presentations are now available on the website YVAAMT.com/yvaa-resources.
The links are available for all talks. For mine, we were having microphone issues which I found very distracting.

tahanson43206 · 2024-05-26 06:17:08

Many thank to Oldfart1939 for the link to the Astronomical Association web site and to the folder where the videos are stored.

There are a number of interesting looking videos, including the one by Dr. Bell that GW Johnson and I attended online.

YVAA Winter Lecture Series #5 is the one featuring the talk on Dr. Harold Urey and his experiments with lightning to start life.

The web site is: https://yvaamt.com/yvaa-resources

Update midway through the video...

This presentation is (from my perspective) very well done... The slides are excellent, and the talk itself is audible. if there were microphone problems I didn't notice anything.

The biography of Harold Urey includes his support of the Manhattan Project during World War II.

At the 18+ minute mark I see an AI generated image ... clever use of the technology

The talk itself is about 33 minutes ...

I'm hoping other NewMars members will take the 33 minutes to attend this presentation and perhaps ? provide some feedback for Oldfart1939.

The activity that is the focus of this talk might well have occurred on Mas as well. If that is the case, then the robot explorers should find evidence in their study of the regolith.

Update at 25 minutes mark .... we are looking at the same slide for the last 10 minutes of the talk...

It reads:

What are the next experiments?

- The addition of sulfur compounds to the atmosphere
- Run it again under volcanic conditions
- Optical activity of amino acids

I'd like to encourage you (Oldfart1939) to prepare this talk for another meeting, and add slides to illustrate the ideas you are discussing in the audio.

I'm not sure what the slides would look like, but the AI artists might be able to come up with something interesting.

(th)

tahanson43206 · 2024-05-26 07:24:14

Thanks (again) to Oldfart1939 for alerting GW Johnson and me to the live presentation by Dr. Jim Bell...

The video is available at the Yellow Valley Astronomical Association web site.

It is YVAA Winter Lecture #4 - Jim Bell - Post Cards from Mars and the sample return mission

The video is 1 hour long, and packed with images.

https://yvaamt.com/yvaa-resources

Something to watch for at (about) 6 minutes in is an adjustment so the audience could see the slides.

Thomas-
We were having more than just microphone issues, and I was using a club-provided computer that wasn't responding to my commands. But we need to thank Stefanie Rickhoff for her inputs to this talk.
More really GOOD club news is: we now have a donated "Obsession" Dobsonian telescope sporting a 12.5" Zambuto mirror! This will be used at our club star parties held at the Pictograph State Park later this Summer. The same anonymous donor has given an 18" "Obsession" with it's Zambuto mirror to the Bozeman, MT Chapter of the YVAA.

For Oldfart1939 re terrific addition to Polaris topic!

Thanks for the link to this video! For NewMars members who might be interested, the video is 42 minutes long.

I'm looking forward to watching the entire production soon, and also looking forward to any comments our members may have about the video or the venture.

For OF1939 re link to Cain and friends ...

Oldfart1939 wrote:

Here's the link to another video from Fraser Cain, in which Marcus House and Scott Manley combine with Fraser to dissect the entire mission in great detail. A great compilation of footage is included. Oven an hour long, but is the definitive post flight video.
https://www.youtube.com/watch?v=Flv1W6AR-cU&t=15s

Thanks for the link to that interesting review of the two "landings" and in flight video reporting.

The hint I picked up is that the next test might involve attempting to land on a platform in the Indian Ocean.

If there is a NewMars member with insight into how to find out movements of the SpaceX barges, it would be interesting to know if one of them is moving to the Indian Ocean. That would be a long trip, so it might have started already.

On the ** other ** hand, perhaps another barge is under construction ? in India ?
