Also, did anyone get any pics of the eclipse? I missed it. :-(

I'm seeing weird flickers in the sky tonight. Anyone else notice it?

Others on FB got better closeups, but it was still neat to see. Being up in elevation helped!

Here is something you really don't see every day.  A SoLor Tornado on our Sun!

Its an exciting few days , A-index of 50 ,  G3 mgnetic storm and HF radio blackout (R3) (we may even see some aurora is southern Aus )

 and I just noticed the 2Mev flux  has hit 1200 

Thats a busy Sun

cheers,

Solar storm headed toward Earth may disrupt power

March 07, 2012 — WASHINGTON (AP) — The largest solar flare in five years is racing toward Earth, threatening to unleash a torrent of charged particles that could disrupt power grids, GPS and airplane flights.

The sun erupted Tuesday evening, and the effects should start smacking Earth around 7 a.m. EST Thursday, according to forecasters at the federal government's Space Weather Prediction Center. They say the flare is growing as it speeds outward from the sun.

"It's hitting us right in the nose," said Joe Kunches, a scientist for the National Oceanic and Atmospheric Administration. He called it the sun's version of "Super Tuesday." The solar storm is likely to last through Friday morning, but the region that erupted can still send more blasts our way, Kunches said. He said another set of active sunspots is ready to aim at Earth right after this.

But for now, scientists are waiting to see what happens Thursday when the charged particles hit Earth at 4 million mph. NASA solar physicist Alex Young added, "It could give us a bit of a jolt." But he said this is far from a super solar storm.

The storm is coming after an earlier and weaker solar eruption happened Sunday, Kunches said. This newer blast of particles will probably arrive slightly later than forecasters first thought. That means for North America the "good" part of a solar storm — the one that creates more noticeable auroras or Northern Lights — will peak Thursday evening. Auroras could dip as far south as the Great Lakes states or lower, Kunches said, but a full moon will make them harder to see.

Auroras are "probably the treat we get when the sun erupts," Kunches said. But there is the potential for widespread problems. Solar storms have three ways they can disrupt technology on Earth: with magnetic, radio and radiation emissions. This is an unusual situation when all three types of solar storm disruptions are likely to be strong, Kunches said.

That means "a whole host of things" could follow, he said. The magnetic part of the storm has the potential to trip electrical power grids. Kunches said power companies around the Earth have been alerted for possible outages. The timing and speed of the storm determines whether it will knock off power grids, he said.

In 1989, a strong solar storm knocked out the power grid in Quebec, causing 6 million people to lose power. Solar storms can also make global positioning systems less accurate, which is mostly a problem for precision drilling and other technologies, Kunches said. There also could be GPS outages.

The storm also can cause communication problems and added radiation around the north and south poles, which will probably force airlines to reroute flights. Some already have done so, Kunches said. Satellites could be affected by the storm, too. NASA spokesman Rob Navias said the space agency isn't taking any extra precautions to protect astronauts on the International Space Station from added radiation from the solar storm.

Sounds great. Sure will!
