From Worldometer (new deaths yesterday):
DAY USA WORLD Brazil India South Africa
- Wow, the worst ever COVID-19 pandemic day. Tomorrow should be similar. Clearly the result of the holiday season.
- While China reported 55 new cases and no new deaths, Hong Kong, which is part of China, had 60 new cases and one new death.
- Japan had 5460 new cases and 50 new deaths.
- However, the USA had 222,121 new cases and 4259 new deaths, an all-time high.
- I remain hopeful that these high numbers will begin to decline by next week around the time of Joe Biden's inauguration.
- If not, soon thereafter as those vaccinations begin to take effect.
The green flash and green ray are meteorological optical phenomena that sometimes occur transiently around the moment of sunset or sunrise. When the conditions are right, a distinct green spot is briefly visible above the upper rim of the Sun's disk; the green appearance usually lasts for no more than two seconds. Rarely, the green flash can resemble a green ray shooting up from the sunset or sunrise point.
The GREEN is pretty much as you see that color here. It is a kind of chartreuse green. Or, perhaps closer to Midori.Science of this phenomenon:
- Occurs at sunrise and sunset. I don't know of anyone who has seen a sunrise version. I certainly haven't.
- Usually a flash, though sometimes, but rarely, a green ray.
- The whole sky doesn't turn green, only a blip at the top of the setting sun.
- What you see is light refracting, like in a rainbow.
- But in a rainbow, you see all the colors. Why is the flash always green? Actually, it is also, but very rarely, blue.
- The effect is magnified by something scientifically called a mirage. A mirage as used in literature, for example something imagined in a desert, is virtual. There is such a thing as a real mirage.
- As the Sun sets, the first color to show is red, but you can't see it because of the sunlight. Then the color traipses through orange, yellow, green and blue. Towards the end of the setting, only blue and green are left, but the color blue is somehow scattered out of sight, leaving only green.
- The green flash lasts a second or two. However, the Antarctica Richard Byrd party in 1934 reported the green coming and going for 35 minutes. This photo to the right I don't think is a green flash, but it was taken at the South Pole.
- Usually seen over the ocean on a clear day, but this phenomenon also occurs over cloud and mountain tops. A particularly good place to see it is as a pilot flying westward at sunset.
WebExhibits.com has a nice series of photos:
- Juan Gerra
- SciShow (with good explanation)
- Harley Garage (over the Rockey Mountains)
- Noel Keating (Hawaiian sunset)
I thought, I've seen greener ones than those. So on New Year's Day here I made my first attempt at a video. Unfortunately, I was holding the camera, and there was a lot of jiggle. But clearly, you can see a green flash.
