Get flash to fully experience Pearltrees
In order to get a better understanding of coronal mass ejection (CME) events that occur on the Sun, C2H2 researchers create numerical simulations to model real CMEs observed by satellites. Reproducing observed results through simulations helps explain and constrain the underlying physics, boundary conditions, and processes behind a CME’s creation and evolution. To illustrate how numerical simulations are carried out, we describe a case in which a series of CMEs was modeled by C2H2 researchers. X-class flare from AR 9236
Regular contributor M.A. Vukcevic has kindly given permission to reproduce some ongoing research which will be of interest to people learning about earthquakes and their precursor indicators. Vukcevic states: “the tb’s talkshop does not take any responsibility either for statements or data presented. Please note that there are number of the geomag parameters which I have not labelled, in case I decide they are no longer relevant, or if pattern does hold for some time I might be able to publish results.”
The "Solar Flare" is an explosive release of energy (both electromagnetic and charged particles) within a relatively small (but greater than earth-sized) region of the solar atmosphere. Solar flares happen 150 million kilometres (93 million miles) away from Earth but can damage satellites and interfere with terrestrial communications and power supplies. Solar Wind The thermal energy of ionized coronal gas is so great that Sun's gravitational field cannot retain the gas in a confined static atmosphere. Instead, there is a continuous, near-radial, outflow of charged particles into interplanetary space, called solar wind. This highly tenuous plasma carrying mass and angular momentum away from the Sun.

“We stand on the verge of a vast cosmical discovery such as nothing hitherto imagined can compare with.” —Sir John Herschel in 1850, upon the discovery of a link between magnetic storms on Earth and sunspots, to Michael Faraday, the vaunted experimentalist who was investigating the links between electricity and magnetism. Sir John Herschel from 1846 The Year-book of Facts in Science and Art By John Timbs, London: Simpkin, Marshall, and Co. Incredibly, one hundred and sixty years later in the space age, Herschel’s “vast cosmical discovery such as nothing hitherto imagined can compare with,” of an Electric Universe, remains “on the verge.”
Prepare & Fortify National Security: for an inevitable Electromagnetic Pulse (EMP), both natural and man made are deemed likely. One man made device over the center of the USA and detonated near 100-200 miles high, will cripple the USA - coast to coast, and most of the urban areas of Canada and Mexico in an instant. It could take decades to repair our way out of such an event. Within two days there would be no food to buy in any city, nor equipment to run a farm, nor phones, cars, trucks. The sun can be massively more powerful, and be world wide crippling event - except for the Hardened military bases and underground facilities. To secure our National Security, harden our power grid infrastructure-backbone against an EMP – pre-position spare parts & and create a core system hardened to allow something to come back on-line quickly allowing us to build our way out of a crashed grid, and save millions of lives in the short and near term.
Tom Hacker ReporterHerald Thu, 28 Mar 2013 12:20 CDT What is thought to have been a bright meteor, streaking across the predawn Northern Colorado sky Thursday, sparked reports from dozens of early birds who happened to view it. Loveland resident Shawn Kraft caught it as he drove northward on U.S. 287, between Owl Canyon and Livermore, on his daily commute to Laramie where he works for the city as an information technologist. "Here's what I could equate it with," Kraft said. "You know those little sparklers that kids waved around before they were illegal? It was like that.
The GOES X-ray Flux plot contains 5 minute averages of solar X-ray output in the 1-8 Angstrom (0.1-0.8 nm) and 0.5-4.0 Angstrom (0.05-0.4 nm) passbands. Data from the SWPC Primary and Secondary GOES X-ray satellites are shown. Some data dropouts from the Primary satellite will occur during satellite eclipses. Other plots of interest: A black background version of this plot; GOES 1-min X-rays ; SWPC Real-time Monitors . SWPC X-ray alerts are issued at the M5 (5x10E-5 Watts/m2) and X1 (1x10E-4 Watts/m2) levels, based upon 1-minute data. Large X-ray bursts cause short wave fades for HF propagation paths through the sunlit hemisphere.
The GOES X-ray flux plot contains 1 minute averages of solar X-rays in the 1-8 Angstrom (0.1-0.8 nm) and 0.5-4.0 Angstrom (0.05-0.4 nm) passbands. Data from the SWPC Primary GOES X-ray satellite is shown. As of Feb 2008, no Secondary GOES X-ray satellite data is available. Some data dropouts will occur during satellite eclipses. During the spring and fall, GOES satellites experience eclipses in which the Earth or moon blocks the X-ray instrument view to the sun for a short period every day. Eclipse season lasts for about 45 to 60 days and ranges from minutes to just over an hour.

WASHINGTON — An unusual solar flare observed by a NASA space observatory on Tuesday could cause some disruptions to satellite communications and power on Earth over the next day or so, officials said. The potent blast from the Sun unleashed a firestorm of radiation on a level not witnessed since 2006, and will likely lead to moderate geomagnetic storm activity by Wednesday, according to the National Weather Service. “This one was rather dramatic,” said Bill Murtagh, program coordinator at the NWS’s Space Weather Prediction Center, describing the M-2 (medium-sized) solar flare that peaked at 1:41 am Eastern time in the United States, or 0541 GMT.
A METEOR SHOWER IN BROAD DAYLIGHT: The annual Arietid meteor shower peaks this week on June 7th and 8th. The Arietids are unusual because they are daytime meteors; the shower is most intense after sunrise. People who wake up early might notice a small number of Arietids during the dark hours before dawn.
