Blue Moon Lunar Eclipse

On Wednesday, Jan. 31st, the second full Moon of January will pass through
Earth's shadow, producing a rare 'Blue Moon Lunar Eclipse.'

The Moon won't look blue, however. Researchers are predicting a bright
orange eclipse--a forecast based on studies of recent volcanic activity.
Volcanoes, climate change, and lunar eclipses are linked in ways that might
surprise you.

More information about this, along with eclipse observing tips, are
highlighted on today's edition of Spaceweather.com
