NEGATIVE MAGNETIC FIELDS SPARK AURORAS: For the past
three days Earth has been passing through a region of interplanetary
space filled with negative-polarity magnetic fields. This has caused
intermittent geomagnetic storms and beautiful auroras around both poles.

"SPACE LIGHTNING" SIGHTED OVER THE CARIBBEAN: Sprite
season is definitely underway. Only a few days after a widespread
display appeared over Texas, more sprites have popped up near Puerto
Rico. This time the exotic forms of upper atmospheric electricity were
sighted dancing above the sea instead of land. Learn more about
land-vs-sea sprites at http://spaceweather.com.
