+ | PBS NOVA will probably produce an episode on the topic. | ||

+ | That airs tonight on PBS-2. | ||

+ | Great American Eclipse | ||
+ | Explore the spectacular cosmic phenomenon of a total solar eclipse. | ||
+ | PREMIERES: 4/3/24 8pm | ||
+ | 10:12:04 From John Rudy to Everyone: | ||
+ | See Mark Twain' | ||
+ | 10:19:28 From Barry Kort to Everyone: | ||
+ | In the Lewis & Clark Expedition, they relied on a predicted eclipse that would occur when they were in the Montana Territory to calibrate their clock and fix their exact position on that day, thus improving the reliability of their map making along the journey. | ||
+ | 10:33:42 From Bob Primak to Everyone: | ||
+ | On Mars, eclipses (transits) don't block out the Sun, due to the small sizes of the Martian moons. | ||

+ | Moon " | ||
+ | 10:36:52 From Judy & Mike Alexander to Everyone: | ||
+ | the increase in the size of the moon's orbit is due to conservation of angular momentum: because of friction due to earth- and moon-tides, the spin of the earth slows down; the orbit of the moon " | ||
+ | 10:53:04 From Bob Primak to Everyone: | ||
+ | The Northeast, from western Pennsylvania into Maine, have the best shot at seeing clear skies and limited cloud cover. Eclipse forecast for Monday, April 8, 2024. | ||
+ | 10:54:59 From John Rudy to Everyone: | ||
+ | apparently there have been many ads for bogus glasses | ||
+ | 10:56:09 From Bob Primak to Everyone: | ||
+ | Buying glasses in-person (or getting them for free) | ||
+ | If you'd prefer to buy a pair of approved eclipse glasses in person, the AAS recommends stopping by a Home Depot, Lowe's or Walmart to check if they have any in stock. (Some, but not all, locations sell ISO-approved eclipse glasses, according to the AAS.) Additionally, | ||

+ | certain degree of unpreparedness for example the diamond ring and the less well known Bailey' | ||

+ | 11:10:11 From John Rudy to Everyone: | ||
+ | blue moons roughly every 2.7 years on average. | ||
+ | 11:11:08 From Steve Isenberg to Everyone: | ||
+ | But how could you see the eclipse in a plane with windows facing out the side of the plane? | ||
+ | 11:11:24 From Bob Primak to Everyone: | ||
+ | An airliner can't outpace the shadow of the moon during an eclipse. So the advertised " | ||
+ | 11:13:49 From John Rudy to Everyone: | ||
+ | I was on a plane flying near mt Everest. | ||
+ | 11:14:58 From Steve Isenberg to Everyone: | ||
+ | The pilot would apply some changes to the airplane’s controls automatically to maintain level flight. | ||
+ | 11:15:25 From Bob Primak to Everyone: | ||
+ | Problem is that the angle from which the sun is shining (Azimuth) is at a somewhat inconvenient angle compared to flight path. From the plane’s view the sun (and thus eclipse) would be about 7 or 8 o clock when looking at a clockface. Therefore the best would be that when totality shadow starts (or right before), the plane flies in a more northern direction or even a bit northeastern so most people on board would be able to see it clearly since we would then be at a right angle towards the eclipse (9 of clock). But this requires either that the pilot is a bit flexible (like the SW pilot in 2023 who did some zig zags as spur of the moment) or needs proper flight path planning which is what Alaska airlines did. | ||
+ | 11:16:20 From Bob Primak to Everyone: | ||
+ | In this flight path, the pilot does some zig-zags to let passengers on either side of the plane to have a view. | ||
+ | 11:16:34 From tedpk to Everyone: | ||
+ | Airliner should get you above most of the clouds -- so it could be useful -- the SR-71 once flew along the path of totality fast enough to "make time stand still" by doubling the length of totality | ||
+ | 11:17:36 From Steve Isenberg to Everyone: | ||
+ | But the stars would come out during totality, like they do at night | ||
+ | 11:19:56 From John Rudy to Everyone: | ||
+ | Anecdotally, | ||
+ | 11:21:01 From Bob Primak to Everyone: | ||
+ | A nova, not comet, will be present possibly during this eclipse. | ||

+ | The types of effects on short-term memory cited in this study did not go away just by getting extra sleep after being sleep-deprived. It took longer than a few nights to return to normal functions, if I recall correctly. | ||

+ | Tuesday, two days after losing an hour’s sleep for DST, I found myself making a substantial number of lapses and errors for lack of paying adequate attention to what I was doing. | ||

+ | N.B. ~ Business Insider has a PayWall. | ||
+ | 10:34:43 From Bob Primak to Everyone: | ||
+ | I took an extra-early bedtime before Sunday. This took care of my issues, as I woke up "on time" for DST. | ||
+ | 10:35:22 From Barry Kort to Everyone: | ||
+ | I tried that, but I ended up not falling asleep an hour earlier. | ||

+ | 10:42:01 From Barry Kort to Everyone: | ||
