MAJOR SOLAR FLARE: EARLIER TODAY (NOV. 29TH AT 1311UT
Earth-orbiting satellites detected the biggest solar flare in more than 3 years. NASA's Solar Dynamics Observatory recorded this extreme-ultraviolet movie of the M4.4 category blast:
X-rays and UV radiation from the flare ionized the top of Earth's atmosphere, producing a shortwave radio blackout over the South Atlantic: map. Ham radio operators and mariners may have noticed strange propagation effects at frequencies below 20 MHz, with some transmissions below 10 MHz completely extinquished.
Remarkably, this flare was even bigger than it seems. The blast site is located just behind the sun's southeastern limb. As a result, the explosion was partially eclipsed by the body of the sun. It might have been an X-class event.
The flare also hurled a significant coronal mass ejection (CME) into space, shown here in a coronagraph image from the Solar and Heliospheric Observatory (SOHO):
This CME will not hit Earth. It is outside the strikezone for geoeffective solar storms. If, however, it were coming our way, we would be anticipating a strong geomagnetic storm. Maybe next time!
"Next time" could be just days away. The hidden sunspot that produced this major event will rotate onto the Earthside of the sun during the next day or two. Then its ability to spark geomagnetic storms will be greatly increased.

SUNSPOT AR2786 Taken by Eduardo Schaberger Poupeau on November 27, 2020 @ Rafaela, Santa Fe, Argentina
The amazing sunspot AR2786 photographed this morning with regular / bad seeing at 9:14 a.m. (local time GMT-3) For me, that I started only a couple of years ago with solar photography, it is really fascinating to be able to photograph a sunspot of this size. I used a 180mm Maksutov Cassegrain telescope and a ZWO 290MM camera with a Baader Solar Continuum filter.
COMPLETE FOGBOW AND BROCKEN SPECTRE (BROCKENGESPENST) Taken by Heiko Ulbricht on November 27, 2020 @ Radebeul (observatory), Saxony, Germany
Dense fog in the Elbe Valley at the Radebeul observatory made it possible to generate a complete fogbow including a Brocken spectre (Brockengespenst) with the help of a powerful LED flashlight behind my back. The Brocken spectre is my shadow projected into the wall of fog. The 12 mm fisheye is just enough to capture the entire fogbow. The temperature and dew point had approached each other up to 0.3 degrees, but were not yet in the frost range. Canon EOS 6D + 2.8/12 mm Fisheye (F4), ISO 100, 10s

ANDROMEDA OVER PATAGONIA Image Credit & Copyright: Gerardo Ferrarino
How far can you see? The Andromeda Galaxy at 2.5 million light years away is the most distant object easily seen with your unaided eye. Most other apparent denizens of the night sky -- stars, clusters, and nebulae -- typically range from a few hundred to a few thousand light-years away and lie well within our own Milky Way Galaxy. Given its distance, light from Andromeda is likely also the oldest light that you can see. Also known as M31, the Andromeda Galaxy dominates the center of the featured zoomed image, taken from the dunes of Bahía Creek, Patagonia, in southern Argentina. The image is a combination of 45 background images with one foreground image -- all taken with the same camera and from the same location within 90 minutes. M110, a satellite galaxy of Andromenda is visible just below and to the left of M31's core. As cool as it may be to see this neighboring galaxy to our Milky Way with your own eyes, long duration camera exposures can pick up many faint and breathtaking details. Recent data indicates that our Milky Way Galaxy will collide and combine with the similarly-sized Andromeda galaxy in a few billion years.
C/2020 S3 ERASMUS Taken by Gabriel Zaparolli on November 25, 2020 @ Torres, Rio Grande do Sul, Brazil
On the 25th of November, an hour before the sun started to show up, the C/2020 S3 Erasmus appeared on the east horizon, and with that information I decided to go hunting for the comet at Morro das Furnas, a favorable place for astrophotography with a darker environment and check out the result! EXIF Canon T5i + Canon 85mm F/1.8 [STACKING] 525s, F/1.8, ISO 3200 Photographed Obj: C/2020 S3 (Erasmus) GPS: Morro das Furnas, Torres, Rio Grande do Sul, Brazil.
