  1. State of Fear, probably the most enlightening book I have ever read. Global Warming my ass

  2. Sorry DXR, I disagree. The radiation from CH regions is indistinguishable from quiet sun regions except at the higher end of the spectrum - not cooler, or darker (in infrared to visible wavelengths), unlike sunspots. The CH's are always found at both of the poles of the sun, but tend to echo earlier sunspot disturbances towards the mid latitudes, as if they are remnants of the magnetic disturbance that was previously seen as the sunspot. Towards the solar minimum, CH activity takes over from sunspots and flares, causing auroras on earth. The CH areas represent areas of open magnetic field lines - magnetic field lines that do not loop back to the sun, but go outwards through the solar system to join the interplanetary magnetic field, thus are open to releasing plasma, which makes up the particles comprising the solar wind, way out towards the earth and other planets. This is the reason that both of the poles always have coronal holes, like in a bar magnet, the central polar magnetic field does not loop back to the other pole, but goes out into space. At the end of the solar minimum, even the CH activity dies down, because there have been so few sunspots in the previous months. As solar sunspot activity picks up it becomes more confused as both sunspot and CH activity increase, and flares become the major source of auroral activity.
  3. If this deep minimum had happened fifty years ago, when the greatest sunspot maximum of the C20 was going on, would the amateur radio movement ever have got off the ground as it did? How would it have changed society?

  5. Maybe time to review the Ig Nobel prizewinners for the last few years

    Trees and leaves in Worthing, Sussex
  8. http://www.snowballearth.org/index.html What it says on the box, an educational resource for evidence, theories and criticisms re. Snowball Earth. IMO, there should be more sites like this.
  9. A bloke parks in a disabled bay. As he gets out of his car, without any apparent effort or mobility aids, a nearby traffic warden asks: " What's your disability then, mate?" "F****** Tourette's, you p***-***** w******* b********** a******!" came the reply.
  10. Also of interest for several different reasons, Jan Janssens site, SOLAEMON: http://users.telenet.be/j.janssens/Engwelcome.html
  11. Yes. we must wait and see. First we need to wait and see when the minimum has actually been passed. The first swallow sunspot of cycle 24 has been seen, a few more need to come along yet - they may be few and far between this year, who knows?
  12. Then again, NOAA have hedged their bets by doing a high prediction too with up to 154.9 in September and October 2011, released at the same time: http://www.swpc.noaa.gov/ftpdir/weekly/Predict_high.txt
  13. Who am I to upset the happy sunspot cycle 24 rampers - its on its way, and we will know when it's finally here, but the official minimum (month) has not been declared yet. So cycle 23 has a little more mileage in it yet. Of course this cycle may be so unusual as to rewrite the books and the definition of minimum may be changed to fit all eventualities - much as Pluto lost its status as a planet last year. there are 9 EDIT 8 planets in the solar system
  14. It's just North of the equator, unlike the other more diffuse areas, thus polarity is opposite - but still cycle 23, and not quite a spot. I recently learned to think before I put both feet in my mouf
  15. Egg on my face, I'm afraid, I hit the wrong spot http://nwstatic.co.uk/forum/public/style_emoticons/<#EMO_DIR#>/laugh.gif
