Fireball Over Southwest Pondered

September 15, 2011 Comments off

NASA scientists say it was most likely a fireball – a fragment of an asteroid that entered Earth’s atmosphere.

“Based on the reports we heard, a bright meteor was seen over much of the western, southwestern part of the country, California, maybe a little of Arizona and Nevada, maybe more,” said Dr. Ed Krupp, director of Griffith Observatory.

Incoming CME will Bounce Earth’s Magnetic Field Sept 17th

September 15, 2011 Comments off

SpaceWeather.com reports: INCOMING CME: Yesterday, Sept. 14th, an eruption near sunspot 1289 hurled a CME in the general direction of Earth. Analysts at the Goddard Space Weather Lab expect the cloud to deliver a glancing blow to our planet’s magnetic field on Sept 17th around 04:30 UT. High-latitude magnetic storms are possible when the CME arrives.

M2-Class Solar Flare Results in Massive Solar Eruption! (Video)

June 8, 2011 Comments off

Huff Post reports: Yesterday morning, a massive eruption occurred on the sun, producing a solar flare and explosion of high energy particles.

NASA later released footage of the spectacle, described by the Geeked on Goddard blog as being “like a fountain of plasma that blasts out of the solar surface, spreads outward, and collapses to splat back down.” The video shows darker, relatively cool material splashing back onto the sun’s surface as it’s drawn in by the star’s intense magnetic pull.

For anyone concerned about the potential radiation that occurs from a natural occurrence of the sort, the Atlantic Wire reports that because of the sun’s current positioning, the radiation should not have a significant effect when it reaches the earth Wednesday or Thursday.

As NASA scientist C. Alex Young put it, “It’s not necessarily anything spectacular as far as space weather … it’s just really, really beautiful.”

Space Weather reports: STORM WARNING: NOAA forecasters estimate a greater than 25% chance of geomagnetic storms on June 9th. That’s when a CME from the magnificent flare of June 7th is expected to deliver a glancing blow to Earth’s magnetic field. High-latitude sky watchers should be alert for auroras. Aurora alerts: voice, text.

MAGNIFICENT FLARE: On June 7th at 0641 UT, magnetic fields above sunspot complex 1226-1227 became unstable and erupted. The resulting blast produced an M2-class solar flare, an S1-class radiation storm, and an unbelievable movie.

NASA Monitoring Sun Coronal Hole Opening

April 29, 2011 Comments off

CORONAL HOLE: NASA’s Solar Dynamics Observatory is monitoring a hole in the sun’s atmosphere–a “coronal hole.” It is the dark region circled in this extreme ultraviolet image taken during the early hours of April 28th (see below).

Coronal holes are places where the sun’s magnetic field opens up and allows the solar wind to escape. A stream of solar wind flowing from this coronal hole is expected to reach Earth on April 30th-May 1st. NOAA forecasters estimate a 35% chance of geomagnetic activity at that time.

UPDATE: Tsunami Arrival for West Coast

March 11, 2011 Comments off

I AM REPORTING FROM SAN DIEGO WHERE WE WILL GET 3-9 FOOT SURGE.

PLEASE SEND WEST COAST COMMENTS AND INFORMATION OVER THE NEXT TWO HOURS AS THE TSUNAMIS IMPACTS THE COASTLINE AND WE WILL GET THAT INFORMATION POSTED FOR OTHERS TO READ.

MID-MORNING UPDATE: YAHOO NEWS/AP REPORTS
HONOLULU – Tsunami waves swamped Hawaii beaches and brushed the U.S. western coast Friday but didn’t immediately cause major damage after devastating Japan and sparking evacuations throughout the Pacific.

Kauai was the first of the Hawaiian islands struck by the tsunami, which was caused by an earthquake in Japan. Water rushed ashore at least 11 feet high near Kealakekua Bay, on the west side of the Big Island, and reached the lobby of a hotel. Flooding was reported on Maui, and water washed up on roadways on the Big Island.

Scientists and officials warned that the first tsunami waves are not always the strongest and said residents along the coast should watch for strong currents and heed calls for evacuation.

“The tsunami warning is not over,” said Hawaii Gov. Neil Abercrombie. “We are seeing significant adverse activity, particularly on Maui and the Big Island. By no means are we clear in the rest of the state as well.”

High waters reached the U.S. western coast by 11:30 a.m. EST Friday, after evacuations were ordered and beaches closed all along the coast.

EARLY MORNING UPDATE ON WARNING STATUS:

The National Weather Service has upgraded a tsunami watch to a tsunami warning for the West Coast including California, British Columbia, and Alaska.

The warning is in effect for coastal areas of California after a reported 8.9-magnitude earthquake struck off the northeast coast of Japan Thursday night, a National Weather Service official said.

Tsunami warnings mean a “tsunami with significant widespread inundation is imminent or expected. Warnings indicate that widespread dangerous coastal flooding accompanied by powerful currents is possible and may continue to several hours after the initial wave arrival,” according to the Weather Service.

Sea levels are expected to rise off the coast of California by less than a foot by 7:30 a.m. in response to the earthquake, Anderson said.

He advised coastal California residents to stay away from the ocean this morning.

REUTERS REPORTS:

TV pictures showed a vast wall of water carrying buildings and debris across a large swathe of coastal farmland.

Public broadcaster NHK showed flames and black smoke billowing from a building in Odaiba, a Tokyo suburb, and bullet trains to the north of the country were halted.

Black smoke was also pouring out of an industrial area in Yokohama’s Isogo area. TV footage showed boats, cars and trucks floating in water after a small tsunami hit the town of Kamaichi in northern Japan. An overpass, location unknown, appeared to have collapsed into the water. Kyodo news agency said there were reports of fires in the city of Sendai in the northeast.
