APOD: Aurora over Icelandic Fault (2016 Aug 30)

Post by APOD Robot » Tue Aug 30, 2016 4:06 am

Image Aurora over Icelandic Fault

Explanation: Admire the beauty but fear the beast. The beauty is the aurora overhead, here taking the form of great green spiral, seen between picturesque clouds with the bright Moon to the side and stars in the background. The beast is the wave of charged particles that creates the aurora but might, one day, impair civilization. Exactly this week in 1859, following notable auroras seen all across the globe, a pulse of charged particles from a coronal mass ejection (CME) associated with a solar flare impacted Earth's magnetosphere so forcefully that they created the Carrington Event. A relatively direct path between the Sun and the Earth might have been cleared by a preceding CME. What is sure is that the Carrington Event compressed the Earth's magnetic field so violently that currents were created in telegraph wires so great that many wires sparked and gave telegraph operators shocks. Were a Carrington-class event to impact the Earth today, speculation holds that damage might occur to global power grids and electronics on a scale never yet experienced. The featured aurora was imaged last week over Thingvallavatn Lake in Iceland, a lake that partly fills a fault that divides Earth's large Eurasian and North American tectonic plates.

How in the hell someone had get a "bright Moon" at August 30, 2016? New moon will be just in 3 days. Seems as fake.

Fascinating shape for that aurora; a huge curlicue, if you will. The aurora must paint a dynamic picture of Earth's magnetic lines, but in this case, the field must have had a strange shape in the region (... I would have no idea why).

Interesting info regarding the "Carrington Effect". Do you suppose the scientist in the original 1951 "Thing From Another World" - Dr. Carrington, was named after the real life English astronomer? Be a nice tribute. After all they did kill him/it with electricity.

  • Dr. Arthur Carrington's a fun guy one can take a likin' to
    • (and maybe he's even a cryptogam :wink: ).

Dr. Arthur Carrington, character played by Robert Cornthwaite in the 1951 science-fiction movie The Thing From Another World.

Richard Christopher Carrington (26 May 1826 – 27 November 1875) was an English amateur astronomer whose 1859 astronomical observations demonstrated the existence of solar flares as well as suggesting their electrical influence upon the Earth and its aurorae; and whose 1863 records of sunspot observations revealed the differential rotation of the Sun.

Benjamin Carrington FRSE FLS MRCS (18 January 1827 – 18 January 1893) was a leading British botanist and taxonomist in the late 19th century. He was a specialist in bryophytes, cryptogams, fungi & lichens, and wrote extensively on these subjects. (Carrington was President of the Manchester Cryptogamic Society.)

<<A fungus (plural: fungi) is any member of the group of eukaryotic organisms that includes unicellular microorganisms such as yeasts and molds, as well as multicellular fungi that produce familiar fruiting forms known as mushrooms. Similar to animals, fungi are heterotrophs, that is, they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Growth is their means of mobility, except for spores, which may travel through the air or water (a few of which are flagellated). Abundant worldwide, most fungi are inconspicuous because of the small size of their structures, and their cryptic lifestyles in soil, on dead matter.>>

Wow that is a superb image :clap:. It's like a curled chameleon tongue shooting out to catch prey!

Regarding the date the image was acquired it was "August 24, 2016 2:14:10AM (timezone not specified)" according to the Exif data that I was able to obtain.

<<On the official wikidot FAQ for Back to the Future II, Robert Gale (the film's co-Writer and Director) described the DeLorean 99 fire trails thusly (This quote appears to have been sourced (verbatim) from the Official BTTF Fan Club Magazine, Issue #3.):
  • Q. What is the significance of the pair of "backwards 9's" of fire left behind when the DeLorean is struck by lightning?
  • Gale : When the big bolt of lightning hits the DeLorean, it sends the flying vehicle spinning on its axis. As we already know, the DeLorean leaves fire trails behind it when it travels through time. Since in this case, the car was spinning, the fire trails are left behind as spirals instead of the usual straight lines left behind when the car is moving straight ahead.
  • Q. How could the DeLorean travel through time when it gets struck by lightning if it isn't going 88 miles per hour?
  • Gale : The sudden rotation of the DeLorean from the lightning hit accelerates it to 88 miles per hour when it spins.
