SURFING THE HELIOSPHERIC CURRENT SHEET: Yesterday, Oct. 10th, Earth passed through a fold in the heliospheric current sheet.  The crossing sparked bright auroras around the Arctic Circle.  "The lights were fantastic," reports Helge Mortensen, who photographed the display over Kattfjordvannet, Norway:

AURORA OUTBURST: Earth is exiting a stream of solar wind.  As a result, auroras were supposed to subside on Nov. 1st. Instead, the sky over Iceland exploded.  "The Northern Lights came fast and furious," reports Olivier Staiger, who took this picture from the Laxa hotel near Lake Myvatn. What happened?  Earth passed through a region of space filled with negative polarity (south pointing) magnetic fields.  These fields opened a crack in Earth's magnetosphere. Solar wind poured in to fuel the sudden display.
Auroras are supposed to subside even more on Nov. 2nd.  Stay tuned for the unexpected.

UNRULY AURORAS DISOBEY FORECASTS: The forecast for Nov. 2nd called for no auroras.  "But here in Tromso, Norway, the auroras ignored the forecast," reports Michael Zawadzki. "The sky erupted for the second night in a row."   The luminous outburst was so wide, he needed a fisheye lens to capture it all.
"The past two nights have been truly remarkable," marvels Zawadzki.

What went wrong with the forecast?  It didn't anticipate the interplanetary magnetic field (IMF).  On Nov. 1st and 2nd, Earth passed through regions of negative IMF.  Lines of magnetic force wrapped themselves around our planet's magnetosphere  and pried open a crack, allowing solar wind to pour in and fuel the unpredicted display.
More snapshots of last night's surprise display may be found in the aurora gallery.

Lesson learned: At this time of year, when dark wintry skies favor visibility, Arctic sky watchers should remain alert for auroras regardless of the forecast.
