Here is another fantastic shot of the sun as posted on http://www.spaceweather.com
BIG, CRACKLING SUNSPOT: Big sunspot AR2738 is crackling with minor B-class solar flares. Minor? On the sun, it's all relative. A typical B-class solar flare releases as much energy as 100 million WWII atomic bombs. Yesterday, Martin Wise of Trenton, Florida, caught the sunspot in mid-flare:
Only on the sun, which is itself a 1027 ton self-contained nuclear explosion, would such a blast be considered puny.
"Watching sunspot AR2738 and its B-class flares was like watching creation," says Wise, who also made an animation of the blast. "I used a Daystar Quark solar filter to safely take these pictures through my 8-inch Celestron telescope."
And as always, more auroras in Sweden (http://spaceweathergallery.com/indiv_up ... _id=152915)
The GOES X-ray flux shows continual decreased activity from AR2738, which is now flaring in the higher A range with only an occasional low B-class solar flare.
Belgium' Royal Observatory issued this comment for today:
COMMENT: Over the past 24 hours solar activity has been low. The largest
flare was a B5.6 class flare. Active Region (AR) 2738 (Mcintosh class:Hhx;
Mag. type:Alpha) has been most active, producing several B-class flares,
including the B5.6 class flare, which peaked at 14:00 UT (08-Apr-2019).
Former AR 2737 is near the west solar limb, and has shown little activity.
No significant filament channels have been seen on the solar disk. No Earth
directed Coronal Mass Ejections (CMEs) have been detected. There are no
significant low latitude coronal holes on the solar disk. The greater than
10MeV proton flux remained at background levels over the past 24 hours.
Solar activity is expected to remain low over the next 24 hours with a
reasonable chance of a C-class flare from AR 2738.
The solar wind speed has fluctuated between 380 and 480 km/s over the past
24 hours. The total magnetic field strength has fluctuated around 5.0 nT.
The Bz component has been mainly negative, ranging between -7 and +5 nT.
Geomagnetic conditions ranged between Kp index 2-4 (NOAA) and local K index
2-3 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected
to be quiet to unsettled.
