SolarHam is a website all about the Sun and how it affects Earth. It is also an Amateur (Ham) Radio website.|
SolarHam is routinely updated with breaking news, sometimes hours before other Space News websites. You can trust SolarHam.com for the most up to date and accurate solar information on the internet.
SolarHam.com launched on March 15, 2006. The purpose of the website is to provide real time solar news, as well as data from various sources, all located in one spot for easy navigation. Sources include,
NOAA Space Weather Prediction Center (SWPC),
Solar Dynamics Observatory (SDO),
Solar and Heliospheric Observatory (SOHO),
Solar Terrestrial Relations Observatory (STEREO),
Advanced Composition Explorer (ACE),
Large Angle and Spectrometric Coronagraph Experiment (LASCO),
as well as many others.

M3.5 Solar Flare
Sunspot 1996 produced another moderate solar flare, this time an M3.5 event at 03:50 UTC early Tuesday morning. The active region continues to rotate closer towards the west limb. Any future eruptions around this region will be directed mostly away from our planet. Imagery below by SDO/EVE.

Solar Update / Moderate Activity Continues
Good morning. Below is an updated image of the visible solar disk on Tuesday. Solar activity remained at moderate levels during the past 24 hours thanks to a pair of M-Class flares observed around sunspot 1996, and one low level M-Class flare detected around sunspot 2002. The largest of these events was an M3.5 flare at 03:50 UTC centered around region 1996. A noteworthy coronal mass ejection (CME) was not associated with this event when viewing the latest LASCO imagery. Region 1996 continues to rotate closer toward the west limb and is no longer in a good geoeffective position. Region 2002 on the other hand is now moving into a better Earth directed position. Each region will remain a threat for M-Class solar flares today. All other visible regions are currently stable. A potential active region located beyond the northeast limb, the source of a strong farsided flare on March 5th, will begin to rotate into view during the next 24-48 hours. Stay tuned to SolarHam.com for the latest information.

The website fundraiser for 2014-2015 is now officially complete and I am happy to announce that it was another successful campaign. Thanks to 385 kind individuals and my website sponsors, SolarHam.com will remain a full time operation for the next year.
The contest entry period is now closed and the drawing for the framed aurora prints courtesy of Zoltan Kenwell and Brian Drourr will take place on March 15th. Good luck!
A status update in regards to Shirts and Coffee Mugs. A new stock order was placed a few weeks back and will begin to ship once received. Thank You for your patience.
Thank You again to everybody who made a donation during the fundraising drive. Your continued support is appreciated and will ensure the website will continue to evolve.

.24 hr Summary...
Solar activity was moderate for the past 24 hours. Region 1996 (N13W57,
Dac/beta-gamma) produced the largest flare of the period, an M3 flare at
11/0350 UTC. It also produced an M1/Sf flare at 10/2300 UTC, as well as
several C-class flares throughout the period. This region maintained
mixed polarities in the leader spots and exhibited growth in the
intermediate spots. Region 2002 (S17E31, Dac/beta-gamma-delta) continued
to exhibit growth in its intermediate spots, new growth in the trailer
spots, as well as growth and consolidation in the leader spots. It
continues to display a delta magnetic configuration in the intermediate
spot area and exhibit overall areal growth. It was also responsible for
an M-class flare, an M1 at 10/1528 UTC, as well as a few low-level
C-class and subflares. Region 2003 (N06W17, Dao/beta), while relatively
quiet, showed signs of development in its leader spots as well as
overall areal growth. The remaining numbered sunspot regions were stable
and fairly inactive. Solar x-ray background levels have risen to mid
C-level as a result of sustained brightening on the suns southwest
limb. This is likely associated with an eruptive prominence on the limb
(EPL), located near S12W90. There were no Earth-directed coronal mass
ejections observed in satellite imagery.
Solar activity is likely to be moderate (R1-R2, Minor-Moderate) with a
slight chance for an X-class flare (R3 Strong) during the forecast
period (11-13 Mar).

A - Alpha (single polarity spot).
B - Beta (bipolar spot configuration).
G - Gamma (atypical mixture of polarities).
BG - Beta-Gamma (mixture of polarities in a dominantly bipolar configuration).
D - Delta (opposite polarity umbrae within single penumbra).
BD - Beta with a Delta configuration.
BGD - Beta-Gamma with a Delta configuration.
