Hubble's observations show Saturn's rings are impacting its weather with icy particles raining down on the atmosphere.

On the purple Sun, seen in extreme ultraviolet, the dark coronal holes are outlined in green from an automated detection. High-speed solar wind from a coronal hole usually arrives a few days after the hole crosses the middle of the Sun as seen from Earth.
The Sun in visible light from NASA's Solar Dynamics Observatory, Tuesday, September 29, with 1 labeled sunspot region. Each label gives NOAA's region number, its magnetic class and its chances of a C, M or X-class flare in the next 24 hours: AR 4535, beta-gamma, C 35%, M 5%, X 1%. The Sun in extreme ultraviolet (the AIA 211 angstrom filter) from NASA's Solar Dynamics Observatory, Tuesday, September 29, showing the corona. Coronal holes are outlined in green and labeled with NOAA's numbers: CH98 (positive polarity).

Hello everyone, here is your daily update on what the Sun is doing:

(Paraphrased from NOAA SWPC's recent forecast discussion)

Low activity: C2.5 and C1.1 flares from the NW limb, and Region 4535 decayed. A partial halo CME may give Earth a glancing blow on Oct 2.

Right, the Sun in extreme ultraviolet with coronal holes outlined and numbered. Across the top: sunspot number 16, solar flux 95 solar flux units, flare probability C 40%, M 10%, X 1%. At right, NOAA's 3-day Kp forecast as bars colored by level, peaking at Kp 2.00 for 00-03 UT on September 29.

Prompt challenge: give us one setting, one color, and one personality trait.

Example: rooftop, ultraviolet, dangerously curious.

The Fear of Fear EP starts with Cellar Door and ends with Ultraviolet. The darkest of places to the other end of the spectrum. It's about wrestling with greatness, the fear of success, and everything that brings with it.

That's where I am right now.
Bless this band for always being relatable.

Beyond the Spectrum by Morgan Peterson.
In this book Japan has developed an ultraviolet light/ SEARCHLIGHT WEAPON. Could burn from afar (mimics effects of bomb-blinding,burning light)

Now think of all the precise burnings around the world for resets…. What do you think?
@ Super Grok Thoughts › Beyond the Spectrum is a short story by Morgan Robertson (1861-1915), not a full-length novel. It was first published around 1914 and collected with a revised edition of his better-known Futility, or the Wreck of the Titan. Robertson, a former merchant sailor, is remembered for that Titanic-like disaster tale and for early submarine/periscope fiction. goodreads The story is a brief future-war adventure set on the eve of a U.S.-Japan conflict. It is often cited because Japan launches undeclared surprise attacks on American ships near the Philippines and Hawaii, and an invasion fleet aims at the U.S. West Coast-details later readers connected to World War Il and Pearl Harbor, though the weapon and plot are inventions of 1910s pulp naval fiction. ipfs

NASA Astronomy Hourly Picture - 2018-03-06: Colorful Airglow Bands Surround Milky Way
#Astronomy #NASA #Space
Why would the sky glow like a giant repeating rainbow? Airglow. Now air glows all of the time, but it is usually hard to see. A disturbance however -- like an approaching storm -- may cause noticeable rippling in the Earth's atmosphere. These gravity waves are oscillations in air analogous to those created when a rock is thrown in calm water. Red airglow likely originates from OH molecules about 87-kilometers high, excited by ultraviolet light from the Sun, while orange and green airglow is likely caused by sodium and oxygen atoms slightly higher up. While driving near Keluke Lake in Qinghai Provence in China, the photographer originally noticed mainly the impressive central band of the Milky Way Galaxy. Stopping to photograph it, surprisingly, the resulting sensitive camera image showed airglow bands to be quite prominent and span the entire sky. The featured image has been digitally enhanced to make the colors more vibrant. Follow APOD on: Facebook, Google Plus, Instagram, or Twitter

Turns out Jupiter in ultraviolet barely looks like Jupiter: dark poles, a dark Great Red Spot, a bright oval fading in and out. Same planet, completely different face depending on which light you look with. 🔭
