GEOMAGNETIC STORM PREDICTED (G1-CLASS): NOAA forecasters estimate a 55% chance of G1-class geomagnetic storms on Nov. 29th when Earth’s magnetic field is expected to receive a glancing blow from a CME, hurled toward us days ago by a magnetic explosion on the sun. There’s more: A fissure in the sun’s atmosphere is spewing solar wind into space, and the gaseous material could reach Earth on Nov. 29th as well. G1-class storms have little effect on power grids and satellites. However, they can affect migratory animals that navigate using magnetism. Such storms can also cause spectacular auroras around the Arctic Circle. Visit Spaceweather.com for more information and updates.

CRAZY PINK AURORAS

CRAZY PINK AURORAS: Does Solar Minimum turn auroras pink? Sky watchers around the Arctic Circle are starting to wonder.  For the second winter in a row, unusual pink lights have exploded in the night sky when the sun is blank–no sunspots. Solar wind from the “low activity” sun is producing pink auroras so bright that the Arctic landscape itself is turning pink. Visit Spaceweather.com for pictures of these unusual auroras and more information about the underlying physics.

METEOR EXPLODES OVER THE ARCTIC

A meteoroid exploded over the Arctic Circle on Nov. 16th, wiping out the aurora borealis and turning the midnight sky blue.

METEOR EXPLODES OVER THE ARCTIC: On the evening of Nov. 16th, a meteoroid ripped through the atmosphere over the Arctic Circle and exploded. The resulting fireball wiped out the aurora borealis, cast shadows, and turned the night sky blue. Visit Spaceweather.com to see a movie of the explosion, captured accidentally by an automated aurora skycam in northern Finland.

SOLAR WIND, INCOMING: Today, a hole in the sun’s atmosphere is facing Earth. The emerging stream of solar wind could reach our planet as early as Nov. 19th, with G1-class geomagnetic storms possible on Nov. 20th. Sign up for free aurora alerts.

Amazing Auroras

Apparently, the auroras were amazing–and I forgot to look! arrhhh!!!  –Cathy
Space Weather News for Sept. 28, 2017

https://www.facebook.com/spaceweatherdotcomSURPRISINGLY STRONG GEOMAGNETIC STORM: Knowing that a solar wind stream was heading for Earth, forecasters predicted a geomagnetic storm last night. However, they didn’t predict it would be so strong, a G3-class event. During the peak of this surprising space storm, Northern Lights spilled over the Canadian border into more than half a dozen US states. Visit Spaceweather.com for pictures of the display and updates as the solar wind continues to blow.

Auroras predicted for 27th and 28th

GEOMAGNETIC STORM PREDICTED: NOAA forecasters say there is a 65% chance of polar geomagnetic storms on Sept. 27th, increasing to 80% on Sept. 28th, as a stream of high-speed solar wind buffets our planet’s magnetic field.  Isolated periods of moderate G2-class storming could spark Northern Lights in US states as far south as, e.g., New York, Idaho and Washington.

80% chance of polar geomagnetic storms Friday

GEOMAGNETIC STORM WATCH: NOAA forecasters say there is an 80% chance of polar geomagnetic storms on Aug. 4th when a solar wind stream is expected to buffet Earth’s magnetic field. The wind is flowing from a canyon-shaped hole in the sun’s atmosphere, so wide that it is almost bisecting the solar disk. Storm levels could reach G2-category (moderately strong) during the late hours of Aug. 4th, subsiding to G1-category (minor) on Aug. 5th. Visit Spaceweather.com for more information and updates.

CME SWEEPS ASIDE COSMIC RAYS

CME SWEEPS ASIDE COSMIC RAYS: On July 16th, a CME hit Earth’s magnetic field, sparking two days of geomagnetic storms and beautiful auroras. The solar storm cloud also swept aside some of the cosmic rays currently surrounding our planet. A sudden decrease in deep space radiation was detected by a global network of neutron monitors as well as a space weather balloon in the stratosphere over California. Almost a week later, cosmic rays are finally returning to normal. Learn more about this event on today’s edition of Spaceweather.com.

Potential for Aurora Display!

STRONG SOLAR FLARE AND CME: After days of suspenseful quiet, huge sunspot AR2665 finally erupted on July 14th (0209 UT), producing a powerful M2-class solar flare. The explosion was underway for more than two hours and hurled a bright coronal mass ejection (CME) toward Earth. Geomagnetic storms and high-latitude auroras are likely when the CME arrives this weekend. Visit Spaceweather.com for images and updates.

  • Possible aurora display this weekend
  • Citizen scientists are closing in on Planet Nine
  • Moon of Saturn has hydrogen and water

Possible aurora display this weekend: A magnetic filament on the sun exploded on April 9th, hurling a gaseous coronal mass ejection (CME) into space. The bulk of the CME will miss Earth; nevertheless a glancing blow to Earth’s magnetic field is possible this weekend. The impact, if it occurs, could cause magnetic disturbances and auroras around our planet’s poles. Visit today’s edition of Spaceweather.com to view a movie of the instigating explosion and for updates as the CME approaches.
Citizen scientists are closing in on Planet Nine : The Australian team are working in tandem with the public to search for what could possibly be one of the biggest discoveries of the century: a new, very massive planet. In 2016, Caltech astronomer Mike Brown and theoretical astrophysicist Konstantin Batygin announced that they’d found evidence of a massive planet orbiting far off in the annex of the solar system with a predicted orbit of 20,000 years.  Its presence is inferred from the orbit of several Kuiper Belt Objects which have dramatic orbits.  READ MORE

Moon of Saturn has hydrogen and water:  In what is likely to be its final big discovery before it plunges into the gas giant planet Saturn later this year, the NASA spacecraft Cassini has discovered what could be a habitable ocean environment on Enceladus, one of Saturn’s dozens of moons.  The discovery, reported in the journal Science and announced by NASA Thursday, shows there is hydrogen in the massive plumes of gases and water that explode like geysers from Enceladus’s south pole, out of geological features known as “tiger stripes.”   READ MORE from Montreal Gazette And from  Astronomy Magazine:  Researchers published a paper last year suggesting that hydrothermal vents were the source of life on Earth, where chemical reactions fed these early microbes. If that’s the case on Enceladus, the ocean may have microbial life at the very least.  “The hydrogen could be a potential source of chemical energy for any microbes living in Enceladus’ ocean,” Spilker says.
Of course, it may be years or even decades until we know for sure — in September, NASA will intentionally crash Cassini into Saturn to make sure it doesn’t crash land into Titan or Enceladus and accidentally contaminate either potentially habitable moon with Earth bacteria.   Read More from Astronomy Magazine
