Two
solar coronal mass ejections struck Earth's magnetosphere
on Tuesday, one at 0145 UT followed by another at 1745 UT.
Forecasters estimate a 10 to 20% chance of severe geomagnetic
activity during the next 24 hours.
Sky
watchers living above ~50 degrees geomagnetic latitude should
be alert for auroras.
HIGH
SOLAR ACTIVITY: The Sun has entered a highly-active period
with energetic sunspot growth all over the solar disk. Active
region 9393 --one of the largest sunspots in years-- has
a complex delta magnetic field that likely harbors energy
for major X-class solar flares. You can see this huge sunspot
for yourself, but be careful. Use a pinhole projector! Looking
directly at the Sun can cause permanent eye damage.
