ATMOSPHERIC WAVE RIPPLES OVER CHINA: On Nov. 24th, a deep-rippling wave
at the edge of space crossed the night sky above China. Eye-witnesses
saw the airglow layer split in two, and at least one photographer
captured beautiful images of the event. It might be a type of exotic
wave called a "mesospheric bore."
UNEXPECTED SOLAR FLARES: Catching
forecasters off guard, a new sunspot (AR2615) has emerged and it is
crackling with M-class solar flares. Minor radio blackouts are underway
on Nov. 29-30 as pulses of UV and X-radiation ionize the top of Earth's
atmosphere. This is *not* a major space weather event, but it is a
break from the sun's recent deepening quiet.
CLOUDS OVER ANTARCTICA: This just in from NASA's AIM spacecraft: The
sky above Antarctica is glowing electric blue. A ring of bright
noctilucent clouds has formed around the South Pole. The annual
apparition of these clouds is one of the earliest on record, and may
hint at the workings of climate change.
ENCORE: What you can’t see may astound
you. The largest unexplored region of Earth is the ocean. Beneath its
churning surface, oceanographers have recently discovered the largest volcano
in the world – perhaps in the solar system.
Find out what is known – and yet to be discovered – about the marine life of the abyss, and how
a fish called the bristlemouth has grabbed the crown for “most numerous
vertebrate on Earth” from the chicken.

OF A BIG CORONAL HOLE: At the end of October, a hole in the sun's
atmosphere lashed Earth's magnetic field with solar wind, sparking
moderately-strong geomagnetic storms and almost a full week of Arctic
auroras. News flash: It's back. The same "coronal hole" is turning
toward Earth again. Forecasters expect the solar wind to reach Earth
during the late hours of Nov. 22nd with minor G1-class geomagnetic
storms possible on Nov. 23rd.

CYCLE AT LOWEST LEVEL IN 5 YEARS: Sunspot counts have reached their
lowest level in 5 years, a clear sign that Solar Minimum is
approaching. Contrary to popular belief, Solar Minimum is neither dull
nor uneventful. Instead, space weather changes in interesting ways.
Today's edition of Spaceweather.com
lists some of the changes we can expect, including one that is
happening right now: a measurable increase in atmospheric cosmic rays.

Once again the aliens have landed … in theaters. It’s no
spoiler to say that the latest cinematic sci-fi, Arrival,
involves extraterrestrials visiting Earth.
But for some folks, the film’s premise is hardly shocking.
They’re convinced that the aliens have already come. But is there any
proof that aliens are here now or that they landed long ago to, for example,
help build the Egyptian pyramids?
Meanwhile, SETI scientists are deploying their big antennas in an
effort to establish that extraterrestrials exist far beyond Earth.
Find out why – even if E.T. is out there – one scientist says
making contact is a long shot, while another pioneering scientist involved in
SETI remains hopeful … and could aliens be responsible for the peculiar
behavior of two star systems now making the news?

PHOTOBOMBS AURORA OUTBURST: A high-speed stream of solar wind is
buffeting Earth's magnetic field this weekend, causing bright auroras
around the Arctic Circle. While watching the light show last night in

CME SPARKS BRIGHT AURORAS: Arriving later than expected, a CME brushed
against Earth's magnetic field on Nov. 9th, sparking a bright display
of auroras seen mainly from Alaska. More auroras are in the offing as a
new solar wind stream heads in our direction. Estimated time of
arrival: Nov. 11-12.

HURLS PLASMA CLOUD TOWARD EARTH: Yesterday, Nov. 5th, a magnetic
filament on the sun became unstable and erupted. The blast opened a
fiery canyon in the sun's atmosphere and hurled a CME toward Earth.
According to NOAA models, the plasma cloud could strike Earth's
magnetic field on Nov. 8th, triggering G1-class geomagnetic storms and
auroras around the poles.
