Welcome to Summer / Solar Update
Good evening and welcome to Summer in the Northern Hemisphere. Earth facing solar activity remained at very low to low levels and this trend is expected to continue. No Earth directed eruptions were observed in the past 24 hours. A farsided eruption was observed in STEREO Ahead imagery and was the cause of a coronal mass ejection (CME) seen in the attached coronagraph image courtesy of LASCO C3. Because this was a farsided event, the plasma cloud is directed completely away from our planet. Stay tuned to SolarHam.com for the latest spaceweather data and imagery.

Moderate Storm Watch (UPDATED)
A moderate (G2) geomagnetic storm warning is now in effect. A coronal hole solar wind stream above 500 km/s is now geoeffective.

ALERT: Geomagnetic K-index of 6
Threshold Reached: 2016 Jun 14 1955 UTC
Synoptic Period: 1800-2100 UTC
Active Warning: Yes
NOAA Scale: G2 - Moderate

Quick Solar Update
Good afternoon. We now have three numbered regions on the Earth facing disk. Newly assigned sunspot 2554 formed rapidly during the past 12 hours, but is not yet considered a threat for noteworthy solar flares. Existing regions 2552 and 2553 are both fairly stable. More updates whenever necessary. Image below by SDO/HMI.

Region 2552
Region 2552, the only numbered sunspot group on the visible disk, continued to slowly expand during the past 24 hours and is currently producing very minor B-Flares. The region may begin to produce isolated C-Flares as it moves across the northwest quadrant. More updates whenever necessary. Image courtesy of SDO/HMI.

Solar Update
Good evening. Attached is a look at the visible solar disk as we head into Monday. The disk remains blank for the 3rd day in a row. One of the main indicators of solar activity output, the 10.7cm radio flux (solar flux), stands at 79. More quiet is to be expected during the next few days.

In other news, the solar wind remains elevated above 500 km/s. Periods of minor (G1) geomagnetic storming could persist during the next 12 hours at higher latitudes. Stay tuned to SolarHam.com for the latest spaceweather data and imagery.

Coronal Hole Stream / Storm Watch
As expected, a coronal hole stream is now geoeffective. Minor (G1) geomagnetic storming is being observed at higher latitudes. A watch for moderate (G2) storm conditions has been extended until 22:00 UTC (June 5). Sky watchers at higher latitudes should be alert for visual aurora.

Solar Update
Good evening and welcome to a quiet start to June. Overall solar activity continues to confirm that we are well passed solar maximum and on a slow road to solar minimum within the next 5 years. Currently both visible numbered regions, 2550 and 2551, are stable and not a likely threat for noteworthy solar flares. A filament eruption was observed towards the northeast limb on Wednesday evening but is not likely to impact our planet.

Attached image below shows a middle latitude coronal (83) on Wednesday. This zone will turn into a geoeffective position by as early as this weekend and an increased solar wind stream could provide a period of enhanced geomagnetic activity at higher Earth latitudes. More updates in the days ahead.
