Website Operations
A notice regarding the SolarHam website and day to day operations.

I will be on vacation this week so the SolarHam website will not be regularly updated until I return on August 25th. The site will remain accessible and you will still be able to find all of the information you need regarding current spaceweather data and imagery.

Thanks for visiting and so long for now!

Solar Activity Now Moderate
Solar activity is now officially at moderate levels. New region 2672, now turning into view off the east limb, produced an M1.1 flare at 01:52 UTC (Aug 20). Image below is courtesy of the Solar Dynamics Observatory (SDO). Additional flaring may be possible as the active region continues to rotate into Earth view.

August 18, 2017 @ 16:54 UTC
Active Region Approaching
An active region currently a few days away from rotating into view from behind the east limb appears to be producing C-Flares and possible moderate M-Flares. More updates regarding this likely sunspot during the next few days.

Minor Storming Observed
A high speed coronal hole stream reached Earth on Thursday and sparked minor (G1) geomagnetic storming at higher latitudes. Isolated periods of minor storming could persist during the next 24 hours. High latitude sky watchers should remain alert for visible aurora.

Prepared jointly by the U.S. Dept. of Commerce, NOAA,
Space Weather Prediction Center.
UPDATED 2017 August 20 0030 UTC

.24 hr Summary...
Solar activity remained at low levels. Multiple C-class flare activity
was observed, particularly from an area of enhanced brightening on or
just behind the E limb. Region 2671 (N12E08, Fkc/beta-gamma) also
produced a few C-class flares. The largest event of the period was a
C7/Sf flare, with an associated Type II (928 km/s) radio sweep, observed
at 19/2155 UTC from Region 2671. Coronal dimming was observed to the
north of the Region in SDO/AIA 193 imagery beginning at 19/2143 UTC
suggesting a CME was lifting off. We are currently awaiting updated
coronagraph imagery to determine if there is an Earth-directed
component.

Region 2671 exhibited some elongation along its E-W axis with some minor
intermediate spot consolidation.

.Forecast...
For the next three days (20-22 Aug), solar activity is likely to be at
low levels with a slight chance of M-class flares (R1-R2; Minor-Moderate
radio blackouts).
