Space Weather & Football: Solar Eclipse this Saturday

Submitted by markp on October 11th, 2023 at 11:43 AM

The moon's shadow will sweep across the country Saturday morning/afternoon and will significantly darken some noon games.

In Ann Arbor, the eclipse will go from 11:45 am to 2:25 pm, peaking at 1:03 pm when the sun will be about 35% obscured by the moon (0.47 magnitude*). Combine that with the forecast calling for a lot of clouds and rain and this may feel more like a night game.

Notable teams/darkness (all 12n kicks):

  • TEM @ NTX (0.86m)
  • ARK @ ALA (0.69)
  • SYR @ FSU (0.67)
  • UGA @ VAN (0.62)
  • OSU @ PUR (0.55)
  • IND @ MICH (0.47)
  • MSU @ RUT (0.36)

Notes:

  • North Texas should be the best eclipse viewing (most obscured + clearest skies)
  • FSU or even MICH could be the darkest game depending on the weather
  • Even east coast games like MSU @ RUT will probably appear noticeably dim/weird on TV
  • Too bad UCLA @ Oregon State (0.94) and SJSU @ NM (0.97) take place well after the eclipse has finished :(

*Pop-POP!

This is the Ring of Fire eclipse.  The moon is a bit further away from the earth, so more of the sun is exposed.  You can’t look directly at it without harming your eyes.

The eclipse 7 years ago allowed viewers (like me and the fam) to look directly at the eclipse (for a brief period of time) without eye protection.  It was so dark that cicadas got fooled and went into full night time noise making.

Why North Texas? This map says San Antonio, but I'd love it if it were a little further north.

Wait until next year, It might occur in April when 98% coverage in A2 and then 100% at Toledo. The max will go from about east TX to Lake Erie as the path of total eclipse. (Don't quote me on the exact date, will have to look it up, but it will be big news as we get closer to that event)

Edit: the date will be April 8th, see the comments from Nittany Fan down below.

Unfortunately, I think you might be over estimating how much this will have an affect on perceived brightness. Brightness typically varies by orders of magnitude from inside to outside and with cloud cover etc.

While there's no guarantee how things will actually appear in each location (clouds, rain, humidity, camera settings, etc.), blocking 80% of the sun (Denton, TX) should definitely be noticeable.

In other areas like AA (where the sun will 35% obscured) perhaps it'll make a gloomy, overcast day appear more so.

In either case, this should be somewhere between unnoticeable and the apocalypse. 🤣

I don't like being the downer here, but:

Blocking 80% isn't noticeable, our eyes adjust. To put this in perspective, cloud cover blocks 90% of light and we still see fine on a cloudy day.

Ann Arbor will be interesting light wise if the cloud cover is present, but even then it still won't seem like a night game from this.

Unless they mess with TV feeds, we won't notice differences on East Coast games with such small amounts being blocked.

In other words: eyes being incredible 1, space 0.

Further proof, there's no such thing as "normal" when OSU visits Purdue.

FWIW, even if it was a cloudless day in AA, the sun being 40% obscured wouldn't really be noticed by anyone at all.  You need it to get to 90%+ to be distinctly noticeable levels.

For those not aware ---- parts of America will experience a TOTAL solar eclipse next spring, on Monday April 8, 2024.

The sun will be 98-99% obscured in AA and Detroit.  The path of total eclipse will just barely brush the southeastern corner of Monroe County: that's the only portion of Michigan within totality.  

San Antonio, Austin, Dallas-Fort Worth, Little Rock, Indianapolis, Dayton, Toledo, Cleveland, Buffalo, Rochester NY, Syracuse and Burlington VT are among the cities that get the full show.

Hopefully the weather is good that day!  IMO, it's an event worth traveling for (I traveled to Nebraska to see the August 2017 total eclipse). 

The difference in the experience between 99% totality (Ann Arbor) and 100% totality (Toledo) is HUGE: this is definitely a case where "close enough" absolutely is NOT "close enough."

The Lost Peninsula!  There's a bar (that sells Michigan lottery tickets), a few dozen homes and a marina there, I made a field trip there once out of curiosity.

For the geography nerds, there are a few other small oddities like that:

  • Kentucky Bend: a part of Kentucky only reachable by land via Tennessee.
  • Carter Lake, Iowa: a town of ~ 4000 that is fully west of the Missouri River and fully surrounded by Omaha, but it's still part of Iowa.
  • Point Roberts: a part of Washington State only reachable by land via Canada.  (John Tortorella chose to live here when he coached the Canucks, which was a point of contention with management) 
  • Northwest Angle: same situation, this is a part of Minnesota.

I will be at the game Saturday but I'm waiting for the big eclipse in April where the eclipse will be total if you are willing to venture into Ohio.

As noted above there is a big change between partial and total.   We viewed the 2017 eclipse in Columbia SC.   Living in Virginia it was a relatively short trip so thought would be fun to do but it was WAY cooler than I anticipated.   It was a very hot day and maybe at 50% ish coverage you could start to feel the difference in heat but change in daylight wasn’t very dramatic.  From memory the noticeable difference in diminishing daylight was almost all after 90-95%.  
 

If you haven’t experienced one I recommend.  We decided that day we would do Austin in 2024 for the next one.

May the shadow of the moon fall on a world at peace.

This poetic line from the ABC News Anchor in 1979 is a little haunting - but also a reminder.  We always have something to aspire to.

I am heading to the centerline of the path of "annularity", west of SA, TX. Hoping the sky will remain clear. I expect some dimming, almost an eerie lighting where I am going. I do not expect the lighting to be too different outside the band. 

This would be the closest I get to the totality since my first and so far last one in 1995. Excited. Very excited.

If you're not in totality, it's hard to notice much visually unless you are wearing eclipse glasses and staring directly at the sun.  Do not stare at the sun if you do not have eclipse glasses.

However, if you happen to be in a very dry or desert area, you can notice the temperature dropping even though the sun looks the same.  Since dry areas cool down quickly without sunlight, when the sun is 50% covered, you can't see it with the naked eye but you can feel it.  Pretty neat experience if you can find a dry climate to observe the eclipse in.

Good  info on this. Given the very thick cloud cover and the rain, the scene will certainly look like a night game sometime in the 2nd and 3rd quarters. It will look eerie outside.

MSU @ RUT (0.36)

It would be better for everyone involved if we could get the magnitude cranked way up for this one. The darker the better. We've got to protect the children.

It reminds me of the Space Lord Mother Fucker song, .from Monster Magnet.  It was changed to Mother, Mother for radio play. LOL
