AI 2027 A research-backed AI scenario forecast.

Wondering about AI and how it will go over the next decade or two? .... maybe check this out. It is a thinker, for sure. Yes, making such predictions is a challenge. These folk are smart and know their stuff. It is a potential scenario, and not a good one for humanity. ai-2027.com

A splendid moment on this day in 2017: Casper, Wyoming, perfect weather, the whole family and totality.

Aug 3 sunspots

Excellent seeing conditions today, and the Sun is sharing some excellent sunspot groups as well. There is a forest fire smoke layer above us, but very steady conditions prevail.

Sunspots today: the Sun is very active still as we make our way through solar maximum. Good seeing conditions, so I though I would share.

The hummingbirds arrived yesterday. That makes me happy. It was raining, so here are two wet-bird photos from the backyard. #Nikon

Marching onwards: huge sunspot groups continues to impress.

Monstrous sunspot has come into full view... and we have a clear-sky moment! This with TV85 and Baader solar wedge. #Nikon. #EduSky #Astrophotography #Astronomy

Lunar eclipse series

lunar eclipse totality

Nice views of the lunar eclipe last night. Had some visitors to the observatory: all good, just a little frosty by the end of the night ;-) These through a 500mm tripod mounted Z9 with 500mm lens. #astronomy #astrophotography #moon #eclipse #astrosky #astrophotography #edusky

February 12, 2025 Yesterday afternoon, in a bizarre performance, President Donald Trump hosted reporters in the Oval Office, the formal working space of the President of the United States.

February 12, 2025

Young researchers mobilize to protest Trump administration’s science policies Stunned by attacks on the scientific research system, early career scientists plan a D.C. demonstration and a national ‘Stand Up for Science’ event.

Thanks to @statnews.com for featuring #standupforscience2025! www.statnews.com/2025/02/13/r...

We’re Standing Up for Science because we believe science is for everyone and benefits everyone. It’s time to advocate for science, funding, and education. Join us on March 7th in DC and Nationwide!

It's nice to wake up to a fresh layer of snow... and it is still snowing! The perfect opportunity(!) I say to myself, grabbing camera, and macro lens while still in my pajamas! Here are some of the better ones. The flakes are quite ornate and delicate this time.

Results of the latest development tank. This is Ilford Delta 3200 exposed and developed at 1600iso. This is also a first run with the Leica M6 and a newly acquired Zeiss Sonnar 50mm f/1.5. Chemistry was Ilford Microphen. I am liking the results.

Some flakes from yesterday's snowfall. It remained cold with larger flakes this time around, making for a better session. Funny that I was exercising (stationary bike), so must have looked pretty darned funny to the neighbors running out with camera in bike shorts and a t-shirt to grab these.

Moon with Earthshine and the planet Venus.

Venus and Moon (with Earthshine).... nice view tonight.

I've pretty much started limiting my own access to the news by allowing myself an hour each dat to catch up on the various happenings out there in the world, and always starting with non-USA-sourced presentation. The USA is greatly divided and very much broken.

Happy start of Summer for those in the southern hemisphere, and happy Winter for those up north.

B33 Horsehead nebula in Orion

...and one fun image taken on Monday night of B33, the Horsehead Nebula, in Orion. This one with a 0.3m f/8 Maksutov at Las Campanas, Chile. 40 minutes in Lum binned 2x2. They have the best seeing conditions of any observatory I have known. Amazing. #astrophotography #science #EduSky

Wrapping up the fall term: three days remaining to get everything done, comments written and then a short break for Thanksgiving before the start of Winter Term... then two weeks before the holiday break. Winter: 2 Sections of Selected Topics in Astronomy, 1 of Intro physics, and 1 Intro Astro.

It looks more and more like the US Govt is going to be led by daytime television personalities. Let's see: Lost in Space? F-Troop, Gilligan's Island? Were are we off to next?

BL Cam, a pulsating variable star of the SX Phe type. The mage has this remarkable object very close to center. The light curve was taken last night over 1.5 hours in V (filter). You'll see some data points brighter than expected: clouds lit by moonlight was the cause. #astronomy #astrophotography

Comet 2023 A3 also gave us a good visit this fall. Our earliest sighting was as it passed aphelion: we caught it from the top floor of the school library (8 stories). As the days progressed, the comet was more visible in the night-time sky.

We have had three excellent aurorae storms visible this year from Exeter (NH, USA). This last one was so bright, one could read by it: full color and already active by sunset. Our magnetometer captured all the data it could get, down to the nT. Exciting times.

Finished the last week of regular fall term classes. Now it is time for that last week: exam days.... which means I can sit in front of computer and write comments and finish grading, just in time for Thanksgiving. Here we go!
