The Sun released this weak non-Earth directed coronal mass ejection (CME) on December 24, 2018.
Merry Xmas!

An eruptive M-class flare followed by a global coronal wave.
The highest resolution data from the corona we currently get on a regular basis are from the Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory (SDO), however, even higher resolution images have been obtained during a sounding rocket flight by the High-resolution Coronal Imager (Hi-C). The scientific objectives of Hi-C are central to the goal of understanding the Sun’s activity and its effects on the terrestrial environment by providing unprecedented views of small-scale structures in the solar atmosphere.
The Hi-C instrument is scheduled to launch on a sounding rocket May 29, 2018. This will be the third launch of the Hi-C instrument.

New active region producing C-class flares
Finally! An eruptive new flare region is rotating into view!
B-class flare from solar active region 12703
C-class (4.6) flare eruption on the eastern limb of the Sun.
Richard Feynman (above) included a poem in his address to the National Academy of Sciences:
I stand at the seashore, alone, and start to think.
There are the rushing waves
mountains of molecules
each stupidly minding its own business
trillions apart
yet forming white surf in unison
Ages on ages
before any eyes could see
year after year
thunderously pounding the shore as now.
For whom, for what?
On a dead planet
with no life to entertain.
Never at rest
tortured by energy
wasted prodigiously by the Sun
poured into space.
A mite makes the sea roar.
Deep in the sea
all molecules repeat
the patterns of one another
till complex new ones are formed.
They make others like themselves
and a new dance starts.
Growing in size and complexity
living things
masses of atoms
DNA, protein
dancing a pattern ever more intricate.
Out of the cradle
onto dry land
here it is
standing:
atoms with consciousness;
matter with curiosity.
Stands at the sea,
wonders at wondering: I
a universe of atoms
an atom in the Universe.
Happy
World Poetry Day!
Filament liftoff followed by coronal dimming (black regions) and post-eruptive arcades (March 6, 2018).
Sunspot region AR2699 is back!
AR2699
produced
a
long-duration
C-class flare, and an Earth-directed CME
on its previous rotation but now it’s just a plage region. There is also a lovely coronal prominence cavity on the south-east limb of the Sun.
Active region 12700 produced a small B-class flare on Feb. 28.
The evolution of a weak active region on the Sun. Region 2700 is a simple beta (bipolar) magnetic group.
Flare ribbons & post-flare loops
Region 2699 produced
a
long-duration
C-class flare and released an Earth-directed CME on Feb. 11-12, 2018. The solar storm arrived at Earth on Feb. 15.
Active region 12699
is rotating out of view over the western limb.
So long, and thanks for all the flares (and CME)!
