I'm on it. My TV has been on the science channel all day. One of the few times the entire day has been devoted to "real" science. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |

Hooray, Mike Rowe is doing the narrating again this season. His voice is the easiest to listen to. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |

Astronomers Reveal New Secrets Of Sun's Coronal Rain Earth's nearest star has bad weather, too. The sun's squalls, however, involve more than just a little rain and lightning. Huge droplets of hot plasma about the size of Maine fall from the sun's outer atmosphere (the corona) down toward its surface going 124,274 mph (200,000 km/h). http://www.huffingtonpost.com/2014/07/14/coronal-rain-sun-video_n_5582965.html Video with link. |

Now that's some bad weather. I saw that the sun rings too. That is how they are discovering so much about what goes on inside. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |

Two years ago this week the Sun let off one of its periodic solar flares, and a new analysis of its force shows that human civilization had a very near miss indeed. http://www.theregister.co.uk/2014/07/26/two_years_ago_earth_missed_solar_doom_by_just_one_week/ |

It's my contention that increased solar intensity is responsible foe any warming trend if there is actually one at all. |

I think that the Sun is entering a quiet period with few sunspots. The Maunder Minimum was corresponding to a Little Glacial Age. Tullio |

Tullio Well perhaps we are cooling as some have asserted. In the past there was an apparent correlation with sun spot activity and temperature on Earth. I am thinking of these coronal mass ejections though. The most recent one that just missed creating havoc on Earth was more severe than anything in the past 150 years. So there may be other events (random?) or cycles that cause a fluctuating amount of total energy output from our Star. I am relying on subjective memories and think that the sun feels more intense now than I remember. I spent 4 years as a kid in Key West Florida which is the southern most point in the United States. It seems that now, here in Tennessee (1000 miles North) the sun feels much hotter than I remember it then, back 60 years ago. Here is what I have posted before. It is from the Internet so it must be correct !! From Goddard Space Flight Center: Since the late 1970s, the amount of solar radiation the sun emits, during times of quiet sunspot activity, has increased by nearly .05 percent per decade, according to a NASA funded study. "This trend is important because, if sustained over many decades, it could cause significant climate change," said Richard Willson, a researcher affiliated with NASA's Goddard Institute for Space Studies and Columbia University's Earth Institute, New York. He is the lead author of the study recently published in Geophysical Research Letters. "Historical records of solar activity indicate that solar radiation has been increasing since the late 19th century. If a trend, comparable to the one found in this study, persisted throughout the 20th century, it would have provided a significant component of the global warming the Intergovernmental Panel on Climate Change reports to have occurred over the past 100 years," he said |

I usually get my data from NOAA. Here is what it says about the Sun today: IA. Analysis of Solar Active Regions and Activity from 24/2100Z to 25/2100Z: Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C2 event observed at 25/0702Z from Region 2121 (N08E30). There are currently 4 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for a C-class flares on days one and two (26 Jul, 27 Jul) and likely to be low with a slight chance for an M-class flare on day three (28 Jul). IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 387 km/s at 25/1501Z. Total IMF reached 6 nT at 25/1259Z. The maximum southward component of Bz reached -6 nT at 25/0612Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (26 Jul), quiet levels on day two (27 Jul) and quiet to active levels on day three (28 Jul). |

I was like "WTF" too, then I took note that they are talking about an event in January. I wish the press would stop with the doom and gloom stories about CMEs. Gee, it's still solar peak. Shit gonna fly. Solar peak is roughly every 11 years. Every cycle sees at least one high-X class flare, and many smaller X-class flares. Humans have been on Earth for approximately 200,000 years. I think we'll be fine. IMHO, the mass-media reports on this kind of thing cater to christian extremists. People who know better, know better. Christian extremists are always claiming each new "sign" is the end of the world, and if anyone hasn't noticed, they are like all going nuts these days on virtually everything, even to the point that a HUGE number of them are actually arming and training for a Civil War.

[Okay, Censors, the text is now edited, and not "obcene", and the "swearing" has been removed. I have chosen what I hope are appropriate adjectives. Given that the followers of the deniers are arming, training, and ubiquitously threatening a civil war in the United States, I personally find a few adjectives the least offensive thing about the scenario. When they threaten to blow the tops of the heads off of our children... Check them out on Facebook sometime, they are everywhere, especially the christian pages.] If you are a not a fossil fuel industry employee, you might want to stop buying into their crap. That professional a-hole in Calgary that came up with the whole "Global Warming is caused by the Solar Cycle" crap, contracts to coal companies, and is a Political Science Professor at Univ. of Calgary. Even his book on "Terrorism" was a chamberpot of feces, for failing to recognize that right wing christian Terrorism is the most notorious and active threat on North American soil, and his ideas on Islamic Terrorism (the only kind he seems to recognize) would lead to increased Terrorism, and here we are over a decade later, and his suggestions to the Prime Minister's Commission on Terrorism have indeed led to more. Before buying into to denier lies, look into their background. All of it. The asshat in Calgary is a freaking troll, and personal friend of Harper, while channeling for Canadian audiences, a Rush Limbaugh, Sean Hannity, and Glenn Beck mentality. Always check the credibility of your sources, and of their sources, especially who butters their bread.

Spaceweather.com has some neat gadgets, but mostly they parse the data from ftp://ftp.swpc.noaa.gov/pub/indices/, so, it's simply a repackaging of the same thing.

All of this over a geoeffective X1? I think I'm about to say some more of those naughty words the prudes don't like to hear.

ok people here is the site you need for all info on the sun 2 links i will provide are the official sites http://sohowww.nascom.nasa.gov/ SOHO http://sdo.gsfc.nasa.gov/data/ SDO |

Although SOHO has it's uses still (the coronagraphs and MDI), SDO is far more capable. Also, you do need to combine that with other data from SWPC to make proper use of it.
