NO METEOR OUTBURST? So far we have received no reports of a predicted gamma Delphinid meteor outburst on June 11th. If there was a stream of comet debris near Earth's orbit, either we missed it, or it was populated by meteoroids too small to produce naked-eye meteors. [Meteor radar]

AURORAS + NOCTILUCENT CLOUDS: On Sunday, June 9th, Alan Dyer of Gleichen, Alberta, Canada, went outside to see the colors of the sunset. He got more than he bargained for. Stacked atop the rosy glow of twilight were dual bands of electric-blue noctilucent clouds and green auroras:

"At times the auroral curtains appeared superimposed on the noctilucent clouds," says Dyer. "It isn't often we see the two phenomena together."

That's because they are completely unrelated. Auroras are caused by energetic particles from the sun raining down on Earth's upper atmosphere, causing the air to glow like the picture tube of a color TV. Noctilucent clouds are made of tiny ice crystals wrapped around bits of meteor smoke. Their electric-blue color comes from the scattering of high altitude sunlight. On June 9th the two phenomena overlapped for a rare display.

Mount Veniaminof volcano erupts in Alaska

The Extinction Protocol -June11,20113

 

 

A weak eruptive activity has started from the volcano. Since last night, weak ash emissions have appeared from the central cone of the caldera of the volcano. The new activity is accompanied by a persistent steam plume and increasing volcanic tremor. So far there seem to be no lava flows or other significant eruptive processes. The new ash emissions are very diluted and reach about 200-300 m height. They were first observed on the Aviation camera of Perryville from last night at around 17-18h local time. AVO who has not yet reported about the ash confirmed to Blog Culture Volcan that the plume indeed contains very small amounts of ash, which pose no problems to aviation (for now). The volcano last erupted in 2008. –Volcano Discovery

Ibu volcano (Halmahera Island, Indonesia): lava dome overtops crater rim poses risk of pyroclastic flows

The Extinction Protocol-June 10,2013

 

 As the Indonesian Volcanological Survey (VSI) specified in its latest bulletin, parts of the active lava dome of the volcano have recently (early June) grown higher than the northern crater rim, where it is cut by a valley extending to the northern feet of the stratovolcano. Therefore, potential continued growth of the dome poses the risk of rockfalls and pyroclastic flows reach the northern flanks, where a number of villages are located, namely Pasilulu and Talen. In addition, VSI scientists have detected an increase of seismicity and degassing since early May. This includes volcanic tremor from growing lava dome and deeper earthquakes, possibly related to new magma rising, and the occurrence of notable sulfur smell. Ibu’s activity has been characterized by the slow building of a new lava dome inside the breached summit crater since 1999. While present growth rate is still slow, and no or little incandescence is observed at the moment, the new seismic activity could herald a phase of more vigorous activity in the near future. In that scenario, the occurrence of dangerous landslides and pyroclastic flows would be likely and the northern slopes of the volcano should be considered a high risk zone. –Volcano Discovery

 

Massive waterspout off the southern coast of France shocks residents

June 11, 2013 – FRANCE - A natural phenomenon more common for America, a tornado, has hit the South of France shocking locals and holidaymakers on the Côte d’Azur, the Mediterranean coastline. As thousands in Central Europe are struggling to cope with devastating floods which have already claimed the lives of at least 21 people, a tornado ripped through the French Riviera on Sunday morning. The violently rotating column of air and water formed off the coast not far from popular resort towns of Cannes and Nice. The phenomenon was observed from the Cagnes-sur-Mer commune in southeastern France, rising off to Villeneuve-Loubet and Antibes, reports Nicematin.com. So far, no damage or injury has been reported. The incident is being widely discussed on social networking services where users – some of them freaked out others rather thrilled – share videos and photos of the “tornado.” “OMG there was a mini tornado in my town today. In Nice!” tweeted user nicknamed Sachamallow. “There’s been a tornado in Cannes. I bet the end of the world is approaching! we’re all gonna die you, will see,” noted @Amaandarine.  –RT

 

'Dust Traps' Help Create Planets

Building a planet seems straightforward enough: Just take a disk of dust swirling around a young star, and let it sit. Micron-sized dust particles will collide and clump together, growing in size, until eventually, voilà! One planet. There's a problem, however: Astrophysicists have calculated that once clumps have reached a certain size, collisions with other clumps should smash them to smithereens. Or they should start drifting inward toward the star, where they can't grow further. How then can planets even form?

Astronomers who've imaged the dust disk spinning around a young star 390 light-years from Earth may have found an answer. Viewing the star using the newly unveiled Atacama Large Millimeter/submillimeter Array (ALMA) in northern Chile, the researchers observed a crescent-shaped vortex of gas in the disk that appears to provide a safe haven in which a planetary seed can continue to grow. The vortex essentially creates a dust trap within which large clumps can get larger while avoiding drifting inward long enough to form the rocky core of a planet.
