GEOMAGNETIC STORM: An interplanetary shock wave (possibly a CME)hit Earth's magnetic field during the late hours of May 31st
Space Weather News for May 31, 2013
http://spaceweather.com GEOMAGNETIC STORM: An interplanetary shock wave (possibly a CME) hit Earth's magnetic field during the late hours of May 31st, sparking a polar geomagnetic storm. At the time of this alert, a G1-class storm is underway and solar wind conditions favor high-latitude auroras. Check http://spaceweather.com for details and updates. DON'T MISS THE STORM: Would you like a call when geomagnetic storms are in progress? Storm alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice). |

GEOMAGNETIC STORM: An interplanetary shock wave (possibly a CME)hit Earth's magnetic field during the late hours of May 31st
Howdy Sam! I was just out poking around with binocs, and I thought I saw a ray of blue light reaching up toward Polaris... I've got to go north of my little town to get a good view of Northern Lights, but I figured I'd check SAA and see if Sam had any kind of alert. I'd like to hop in the car and head north, but I've gotta get up early tomorrow...

Marty From http://spaceweather.com "I wasn't expecting to see any lights, but right before the midnight it broke loose and the sky lit up," says Griffith. "Sadly the clouds quickly filled in my little window, and the auroras were gone. Just thankful for what I got so see!" Elsewhere in the USA, auroras were sighted as far south as Colorado, Maryland, Iowa, Wisconsin, and Nebraska. |

Marty My possible observation last night was circumvented by news of my wife's EA on her last day of work before retirement--Liver cancer discovered via CT scan and spread to lungs and elsewhere. -Sam Sam, that's awful! I wish there was something I could say... If thoughts could help I'm pulling for you both... Marty |

GEOMAGNETIC STORM: An interplanetary shock wave (possibly a CME)hit Earth's magnetic field during the late hours of May 31st
Space Weather News for June 1, 2013
http://spaceweather.com AURORA SURPRISE: Last night, Northern Lights spilled across the Canadian border and descended into the contiguous United States as far south as Colorado and Nebraska. The display was caused by the unexpected arrival of an interplanetary shock wave on May 31st. Check http://spaceweather.com for pictures of the display and the odds of a repeat performance tonight. DID YOU MISS THE STORM? Next time get a wake-up call. Aurora and solar flare alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice). |

Now try to imagine what Sirius(b) had to offer as it was quickly burning through its enormous volume of hydrogen, and then helium. |

That's not what I'd asked of you, although it further proves your willing intent to obfuscate and deceive. No wonder our K-12s are so pathetically hopeless and more helpless than ever, as in dumbfounded past the point of no return. |

From the orbit (and spectroscopic data), we find that Sirius A and B have respective masses of 2.12 and 1.03 times that of the Sun. Sirius B is the chief member of a trio of classic white dwarfs, the others Procyon B and 40 Eridani B. Its high mass and tiny radius lead to an amazing average density of 1.7 metric tons per cubic centimeter, roughly a sugar cube. White dwarfs are the end products of ordinary stars like the Sun, tiny remnants that were once nuclear-fusing cores that have run out of fuel. Most are balls of carbon and oxygen whose fates are merely to cool forever. To have evolved first, Sirius B must once have been more massive and luminous than Sirius A. That its mass is now lower is proof that stars lose considerable mass as they die. Given the mass of the white dwarf and the 250 million year age of the system, Sirius B may once have been a hot class B3-B5 star that could have contained as much as 5 to 7 solar masses, the star perhaps losing over 80 percent of itself back into interstellar space through earlier winds. --- From Jim Kalar's Stars http://stars.astro.illinois.edu/sow/sowlist.html |
