New calendar page
Nov. 3rd, 2003 12:20 pmYou know, I'm really enjoying the images in my "Don't Mess With Mother Nature" calendar, but boy does the text get things wrong. This month (coincidentally): "Aurora Borealis".
Ok:
-It's strange to say particles from the sun are blown against the earth by the solar wind. Particles from the sun *are* the solar wind.
-The particles don't turn into light, they have collisions that emit light.
-Open vs locked sugegsts that solar wind hitting the poles gets in whereas solar wind hitting at lower latitudes doesn't. In actuality particles coming in at too low latitudes get redirected along (smoothly varying) field lines to the poles.
************
A life-pattern for me: when I have something meaty I'm planning to write, I tend to put off other writing. This is not good -- I'd rather give myself the freedom to write at whatever level of meatiness is available to me at the time. Hence, a lighter post here while my further writings about Twilight Covening are still pending.
Aurora borealis or the Northern Lights is a phenomenal natural light show which occurs when particles from the sun are blown against the earth by the solar wind. The particles turn into light when they hit the earth's atmosphere. Aurora borealis is only visible in the polar regions because the magnetic field lines which allow the solar wind particles to hit the earth's atmosphere are only open at the poles. The magnetic field is locked at lower latitudes.
