Yowbarb Note: There was a G2 (Moderate) Geomagnetic Storm yesterday.

http://www.spaceweather.com/

SUBSIDING STORMS: The big geomagnetic storm of July 16-17 is finished.  Earth is exiting the wake of the instigating CME and, as a result, geomagnetic activity should remain below G1-storm levels on July 18th

BLANK SUN: Giant sunspot AR2665 has rotated onto the far side of the sun.  It is gone, leaving behind ... nothing. The face of the sun is blank. With the sunspot number back at zero, the sun's march toward Solar Minimum has resumed.

Wow, MadMax, thanks for catching that one. Glad it was not earth-facing.

Image: Gigantic Jet Lightning Near Hawaii Taken by Frankie Lucena on July 24, 2017 @ Mauna Kea Observatory

GIGANTIC JETS OVER HAWAII: Every night, the Gemini cloudcam atop Mauna Kea in Hawaii monitor storms approaching some of the world's largest telescopes. It often captures bright bolts of lightning lancing down to the ground below the towering dormant volcano. On July 24th it captured something lancing up [screen shot farther below]

"This amazing lightning-like phenomenon is known as a Gigantic Jet," says Frankie Lucena of Puerto Rico, who processed the video. "They are related to sprites, but more powerful and easier to see with the naked eye. A special thanks to Steve Cullen for finding the Gigantic Jet at the beginning of the [original video]." 
Cloudcam video caught at least three of these jets springing from the tops of a powerful growing thunderstorm. The tallest of them reached all the way to the ionosphere some 80 km overhead.

"Gigantic Jets are much more rare than sprites," says Oscar van der Velde, a member of the Lightning Research Group at the Universitat Politècnica de Catalunya. "While sprites were discovered in 1989 and have since been photographed by the thousands, it was not until 2001-2002 that Gigantic Jets were first recorded from Puerto Rico and Taiwan." Only a few dozen Gigantic Jets have ever been seen, mostly over open ocean.

Sometimes called "space lightning," Gigantic Jets and their cousins the sprites are true space weather phenomena. They inhabit the upper atmosphere alongside auroras, meteors and noctilucent clouds. Some researchers believe they are linked to cosmic rays: subatomic particles from deep space striking the top of Earth's atmosphere produce secondary electrons that could, in turn, provide the spark for these upward bolts.

The link to cosmic rays is particularly interesting at this time. For the past two years, space weather balloons have observed a steady increase in deep space radiation penetrating our atmosphere. This increase is largely due to the decline in the solar cycle. Flagging solar wind pressure and weakening sunspot magnetic fields allow more cosmic rays into the inner solar system--a trend which is expected to continue for for years to come. These changes could add up to more Gigantic Jets in the future.

T MINUS ONE WEEK: The Great American Solar Eclipse is one week away. On Aug. 21, 2017, the Moon will pass directly in front of the sun, revealing a Diamond Ring, Bailey's Beads, and the sun's ghostly corona. It's a magical experience. The narrow path of totality stretches across the USA from Oregon to South Carolina. What will you see? These animated eclipse maps cover all 50 states:

INCREASING CHANCE OF FLARES: Sunspot AR2671 has developed an unstable 'delta-class' magnetic field that harbors energy for strong M-class or even X-class solar flares. The sunspot is turning toward Earth, so any flares in the days ahead would likely be geoeffective, producing radio blackouts and other effects.

LATEST SOLAR NEWS:
(Sep 4 2028UTC) Numerous solar flares are erupting from the southern sunspot group, and at least one earth-directed CME. Sunspot magnetism suggests flaring will persist for hours!
(Sep 4 1117UTC) There was an M class solar flare from the southern active region. The sunspots are gaining complexity on the south and will be monitored closely today for more eruptive events.

http://spaceweather.com/

SUNSPOT UPDATE: Huge sunspot AR2673, which materialized with shocking speed over the weekend, is seething with activity. Today in Romania, solar photographer Maximilian Teodorescu captured this snapshot of plasma currents surging inside the sunspot's magnetic canopy--apparently on the verge of an explosion:

"It's magnetic madness!" says Teodorescu. "What a complex and beautiful sunspot group!"

AR2673 has already produced two M1-class solar flares on Sept.4th and a bigger explosion may be in the offing. Stay tuned.

(Sep 5 0056UTC) Today’s primary CME is now visible on SOHO Lasco C3. This forecaster estimates a 99% chance of earth impact between 1200UTC on the 6th and 2359 on the 7th. There is a 1% chance of it arriving sooner, which would trigger very strong geomagnetic storms.
