FAST-GROWING SUNSPOT: Solar activity is low, but a fast-growing sunspot could break the spell of quiet. AR1718 has more than doubled in size during the past 48 hours as shown in this movie from the Solar Dynamics Observatory [Click source link for Video]. The magnetic field of AR1718 is rapidly changing and therefore prone to instabilities. If it criss-crosses and reconnects--bang! A solar flare could occur. Because of the sunspot's central location on the solar disk, any eruptions would be Earth-directed.

I had been waiting to post the above WeatherAction.com "Red Warning" chart for April starting from the first "R4" period, due to commence on the 9th, and not for the first time the period before this event held a higher "QV" warning. This "new" style of forecasting from Piers certainly throws my understanding of these ratings out.
I tend to look for the highest "R" rating and post accordingly, however on the past two occasions it was the "R3" rating that had the higher "QV" period and it has come up with a higher then average magnitude Earthquake...see below the result for the past two months for these "R3" events and you will see what I mean.

As odd as it sounds...this amazing weather event is taking place during the current Piers Corbyn "R4" period.....more to follow
I’m not sure I’ve ever seen a storm this big before.
The storm shown here stretches west to east from Newfoundland to Portugal. Its southern tail (cold front) extends into the Caribbean and the north side of its comma head touches southern Greenland.
Not only is it big, but it’s also super intense – comparable to many category 3 hurricanes. The storm’s central pressure, as analyzed by the Ocean Prediction Center, is 953 mb. Estimated peak wave heights are around 25-30 feet.

On March 23rd I posted the end of March "Red Warning" from Piers Corbyn and he stated that the 26th to 31st March would be a high end "R4" period. The chart I posted also mentioned there would be a "significant Earth facing" Coronal Hole and that Piers expected a higher then average risk for a M6.5+ Earthquake as a result of this event.
As you can see from the above SpaceWeather.com report, here is the Coronal Hole....more to follow.

It looks like I have made a rare mistake in the posting of the Piers Corbyn "Red Warning" periods, I left out the "R4" period that immediately followed 13th - 16th March. I understand from Piers that he has recently changed the format of these predictions and that they now occasionally skip a day in between these solar/lunar forecasts and therefore improve his overall monthly percentage.
The above chart takes us up to the end of March and as you can see this period is expected to be very eventful, containing several days with a "R4" rating and ending the month with a high risk of a M6.5+ Earthquake ....stay tuned for more.

The Goldfields supercell. Picture: Walter Ford
On Sunday I posted news of a Magnetic Filament Eruption (15th March) for the Piers Corbyn "R4" Period for period 13th - 16th March, and as regular followers of this topic would know, I then try and hunt down a rare weather event to tie in with these solar events.
I know think I have located a story from Australia that ticks all/most of the boxes for such an event....
Rare glimpse of spectacular supercell - au.news.yahoo.com/thewest
Swirling winds, a lack of rain and a stunning lightning show made for a spectacular sight as a supercell formed over the Goldfields on Sunday.
Kalgoorlie-Boulder meteorological station manager Steven Black said the cloud formation was an "excellent example of a low precipitation supercell".
"Supercells such as these form over dry arid areas and are noticeable due to the circular shape of the lower part of the cloud," Mr Black said.
"The shape comes from the presence of a mesocyclone, which is essentially a little vortex with the air moving around in circles and upwards.
"What made this cloud so spectacular was there was very little rain and made it very easy to view."...click au.news.yahoo.com for more

I posted details of the "R4" event on the 12th March for period 13th - 16th and mentioned this time there was less chance of a M6.5+ Earthquake but exreme weather events could not be ruled out.....more to follow
Report from SpaceWeather.com A magnetic filament snaking around sunspot AR1692 erupted on March 15th at about 0600 UT..The CME left the sun traveling some 900 km/s (2 million mph). Three-dimensional computer models based on observations from SOHO and NASA's twin STEREO probes predict the CME will cross the void between sun and Earth in two days or less. NOAA forecasters estimate a 70% chance of polar geomagnetic storms when the cloud arrives on March 17th. This means the sky could turn green on St. Patrick's Day! High latitude (and possibly even middle latitude) sky watchers should be alert for auroras this weekend....click SpaceWeather.com link for more

During the build up to today's Solar Magnetic Filament Eruption on the surface of the Sun, there may have been an influence felt here on Earth yesterday due to the location of a prominent coronal hole. Remember the eruption is the last stage of a solar event and NOT the start.
California earthquake: Hundreds of aftershocks, more expectedlatimesblogs.latimes.com: The magnitude 4.7 earthquake in Riverside County on Monday has produced hundreds of aftershocks, and experts said that trend should continue for several days.
There have been about 250 aftershocks Tuesday, and there were more than 200 on Monday. All were small and probably not felt by residents in the Anza area.
“I think in a week or so they should be back to normal but that’s still fairly high for that area,” said Kate Hutton, a seismologist at Caltech.
Monday morning's quake, centered near Anza, caused no major damage, but it was felt over what seismologists said was an unusually large area.

The preceding period "R3" for the 7th - 9th March was given a higher "QV" rating of "QV5" and had a corresponding M6.5 Earthquake. On this occasion I was unable to locate a solar flare that coincided with this event.
The impact of this high ranking period is for extreme "weather" events rather then those that relate for Volcano's and Earthquakes.....more to follow.
MAGNETIC ERUPTION ON MARCH 12th - SpaceWeather.com: A magnetic filament in the sun's northern hemisphere erupted today, March 12th, around 1107 UT..The source of the explosion was active region AR1690 on the sun's central meridian. Although AR1690 is almost directly facing our planet, debris from the blast might miss Earth. A CME emerging from the blast site appears to be heading mostly north of the sun-Earth line...click SpaceWeather.com link for more

6.9 magnitude earthquake strikes off Kuril Islands, eastern Russia RT.com
A magnitude 6.9 earthquake has hit the Kuril Islands, south of Russia’s Kamchatka peninsula, according to the United States Geological Survey (USGS). The quake had a depth of 18 miles.
There are no reports of damage.
It's the second quake to hit the Kuril Islands this year. A magnitude 5.5 earthquake struck the Isles on January 1. The Islands were also hit with two earthquakes in November 2012, which measured magnitudes of 6.8 and 5.3.
The Kuril Islands are located 90 kilometers (56 miles) from Severo-Kuril'sk, Russia. Tokyo is located 2,204 kilometers (1,369 miles) away from the Isles.
The population of the Islands is around 19,000 people, and the total land area is about 15,600 square kilometers (6,000 square miles).
