Kizimen (Kamchatka): The lava dome continues to grow at the top of the volcano and produce incandescent rockfalls and small pyroclastic flows, generating ash plumes. A new prominent spine is being extruded at the top and visible on the webcam. The following time-lapse movies show this activity during the day and night:

Karymsky (Kamchatka): Activity has remained elevated. A series of ash emissions caused by moderately strong vulcanian-type explosions occurred over the past days. This morning, an ash plume rose to 8,000 ft (2.4 km) altitude and drifted east.

Shiveluch (Kamchatka): The volcano continues to extrude a new lobe of viscous lava (visible as the dark patch in the webcam image) at the lava dome, as well as produce occasional (usually small) ash explosions.

Poas (Costa Rica): A series of small phreatic eruptions occurred on 20 August at the crater lake. The first occurred at 09:55 (local time), ejecting mud and water to 2-3 m height, and a second one, more powerful, at 11:16 reached heights of 10-20 m.

~ Space Weather Update~ POLAR STORM WARNING:

POLAR STORM WARNING: Two CMEs are heading for Earth. The plasma clouds were expelled from the sun on August 20-21 by a pair of erupting magnetic filaments. NOAA forecasters expect the CMEs to arrive on August 23-24, possibly sparking geomagnetic storms around the poles. Aurora alerts: text, voice.

AURORA SEASON BEGINS: Around the Arctic Circle, summer is long and bright. Auroras vanish in the glow of the midnight sun. News flash: the auroras are back. "Tonight I saw the first auroras of the new season in Oulu, Finland," says Thomas Kast, who took this picture on August 22nd:

"This is how the sky looked at ten minutes past midnight," says Kast. "The orange color on the left is twilight, just between sunset and sunrise, and the waves of the Baltic Sea were lit up by the Full Moon. Above it all were some surprisingly strong Northern lights. I saw needles, purple color, and even a very faint corona."

With autumn approaching, Arctic nights are rapidly darkening. This means more auroras are in the offing. NOAA forecasters estimate a 30% - 45% chance of polar geomagnetic storms on August 22 - 23.

Says Kast: "What a promising start!"

Moon Rises Next to Lick Observatory, Mt. Hamilton

Fabio Pettinati sent SPACE.com a photo he took of the August 2013 "blue moon" rising next to Lick Observatory, Mt. Hamilton, Calif. “Due to the nature of the terrain, there are a handful of spots along the road where one can see the observatory. Of these spots, only this one allowed me this view. I literally had a space of 30 feet to shoot from,” Pettinati wrote SPACE.com in an email.

~ Space Weather Update~ ANOTHER CME IS ON THE WAY:

ANOTHER CME IS ON THE WAY: As Earth passes through the wake of one CME, which did little to stir geomagnetic activity on Aug. 20th, another CME is on the way. NOAA forecasters expect a coronal mass ejection hurled into space yesterday by an erupting magnetic filament to deliver a glancing blow to Earth's magnetic field on Aug. 23rd. High-latitude sky watchers should be alert for auroras. Aurora alerts: text, voice.

SUNDIVING COMET AND FULL-HALO CME: A small comet plunged into the sun on August 20th. Just before it arrived, the sun expelled a magnificent full-halo CME. Click to view a movie from the Solar and Heliospheric Observatory (SOHO):

In the final frames of the movie, the comet can be seen furiously vaporizing. Indeed, those were the comet's final frames. It did not emerge again from its flyby of the hot sun. "With a diameter of perhaps a few tens of meters, this comet was clearly far too small to survive the intense bombardment of solar radiation," comments Karl Battams of the Naval Research Lab, who studies sungrazing comets.

August 21, 2013 – COSTA RICA - The Volcanological and Seismological Observatory of Costa Rica (OVSICORI) recorded two phreatic eruptions at the Poas Volcano yesterday morning. The first eruption occurred at 9:55 a.m. and reached a height of between 2 to 3 meters. The second eruption occurred at 11:16 a.m., reaching an estimated height of 10 to 15 meters. The Director of OVSICORI, Victor Gonzalez, said the eruptions were not unusual for Poas, though did say that the low level of the volcano’s lagoon, despite significant rainfall, was striking. The National Emergency Commission (CNE) maintains a green alert in Turrialba, Poas and Rincon de la Vieja due to phreatic eruptions and seismic activity in recent months. Poas last erupted in 2011. –Inside Costa Rica

 On August 14, a nova in Delphinus shone into existence at 6.8 magnitude, then brightened up to about 4.5, making it naked eye visible from many areas. Likely still visible for at least this coming week, learn how you can find and observe this transient object in the night sky with just binoculars or a small telescope.

Flood waters hide the streets in Blagoveshchensk, Russia, on Friday, August 16. Aid was being flown into the city on Saturday.

(CNN) -- Catastrophic flooding has prompted the evacuation of thousands upon thousands of people in Russia's Far East, a government ministry said Sunday, spurring hasty efforts to set up housing for the displaced.

Russia's emergency ministry said Sunday that 18,000 people had been affected in three regions north of China not far from the Sea of Okhotsk. RIA Novosti, a state-run news agency, identified the affected regions as the Amur region, Khabarovsk Territory and the Jewish Autonomous Region.
