Solar Update
Good evening. Earth facing solar activity is quiet as we head into Thursday. All five visible Earth facing sunspot groups are stable at the moment. There is currently only a low threat (10%) for an isolated moderate M-Flare. Minor C-Flares will be more likely during the next 24 hours.

Below is a beautiful aurora photo sent to us by Sean Kurdziolek from up in Alaska. Image was captured very early Wednesday morning. Great job and thanks for sharing!

Moderate Activity
Solar activity reached moderate levels today. An M1.3 solar flare was detected at 14:44 UTC (Aug 7) and the source region was located just beyond the southwest limb. This was confirmed following a close examination of imagery provided by GOES-13 Solar X-Ray Imager (SXI), SolarSoft also provides the flare location as S15W88. A smaller flare reaching C8.5 was detected shortly afterwards at 15:09 UTC, this time from an active region now turning into view off the east limb. This is likely the return of old region 2567. No major impacts from these events is expected, however more updates will be provided if necessary. Stay tuned to SolarHam.com for the most up to date information.

Aurora Watch
With summer rolling right along here in the northern hemisphere, nights are gradually starting to get longer. This means that the new aurora season is upon us and viewers around the Arctic Circle and beyond are getting prepared for upcoming sky shows. Sandee Rice from Wasilla, Alaska sends us the awesome aurora shot below that she captured on August 3rd during a period of geomagnetic storming.

An additional period of minor (G1) storming will be possible by August 8th when another coronal hole stream is expected to become geoeffective. This may give high latitude sky watchers another chance to view the aurora. More updates in the days ahead.

Storm Warning (UPDATED)
An elevated solar wind stream as measured by both the DSCOVR and ACE spacecrafts is currently moving past Earth. A period of southward Bz is also now being detected and this could contribute to geomagnetic storming at higher latitudes. Sky watchers located at higher latitudes should be alert tonight for visible aurora once dark outside.

UPDATE: Periods of Minor (G1) storming persists at higher latitudes. The Bz component of the interplanetary magnetic field (IMF) remains in a south pointing position and is helping to disturb out geomagnetic field. Sky watchers located at northern regions should remain alert for visible aurora if it is still dark outside.

ALERT: Geomagnetic K-index of 5
Threshold Reached: 2016 Aug 03 0953 UTC
Synoptic Period: 0900-1200 UTC
Active Warning: Yes
NOAA Scale: G1 - Minor

Welcome to August / Solar Update
Good morning and welcome to August. Here is a look at the visible disk today which is for the most part void of sunspots. Solar activity is expected to remain at very low levels today. Image below courtesy of SDO/HMI.

A reminder that a minor (G1) to moderate (G2) geomagnetic storm watch will be in effect for the next 48 hours when a high speed coronal hole stream is expected to become geoeffective. Stay tuned to SolarHam.com where you will find the most up to date spaceweather data and imagery.
