GoodBye to 2192
Good evening. Solar activity during the day on Wednesday was moderate. A number of low level M-Flares were observed around region 2192, including an impulsive M2.3 flare at 21:22 UTC. Attached image courtesy of SDO/HMI shows region 2192 which is now turning onto the west limb and will soon be out of direct Earth view. Will we see the active region again? If it survives the trip around the farside of the sun, the spot cluster will reappear off the east limb during the second week of November. It takes approximately 13 days for an active region to rotate from one limb to another. If you were keeping track at home, region 2192 was responsible for at least 26 M-Class flares and 6 X-Class solar flares while in Earth view, none of which produced a noteworthy CME. Until next time?

X-Flare # 6 Detected
A strong X2.0 solar flare, now the sixth X-Class event around region 2192, was detected at 14:47 UTC. The event triggered a strong R3 radio black on the sunlit side of Earth. So far the event does not appear to be eruptive, meaning a noteworthy CME is not expected. More details to follow. Click HERE for an updated event log.

Let's Make it Five
Region 2192 will not let up. Attached image below courtesy of the Solar Dynamics Observatory (SDO) captures the fifth X-Class solar flare around the active region, this time an X2.0 peaking at 10:56 UTC Sunday morning. A strong R3 radio blackout was observed on the sunlit side of Earth. The latest event so far appears to have failed once again in producing a coronal mass ejection (CME). With the exception of producing bright flashes of energy as magnetic fields tangle, the magnetic layout and structure of the region is having a hard time releasing plamsa.

Region 2192 continued to be productive on Saturday with an X1.0 solar flare peaking at 17:08 UTC. This is now the fourth X-Flare generated by the sprawing active region. Shockingly, all of the events thus far have failed to produce a noteworthy coronal mass ejection (CME). AR 2192 will remain a threat for additional flaring for the remainder of the weekend.

Strong Solar Flare (X3.1)
Sunspot 2192 unleashed the sixth strongest solar flare of the current solar cycle, an X3.1 event peaking at 21:40 UTC on Friday evening. Surprisingly, and disappointingly for sky watchers, the latest event looks to have once again failed to produce a noteworthy CME. Click HERE for the X3.1 event log.

Eclipse and 2192
A partial solar eclipse observed across many parts of North America on Thursday provided many with a great photo opportunity. Not only did they capture the moon passing in front of the sun, but massive sunspot 2192 also shared the spotlight. Attached image below by Ron Cottrell in Arizona is a great example of what many witnessed. More imagery from Thursday can be found on SolarHam Facebook.

Here We Go Again
Region 2192 produced another strong solar flare, this time peaking at X1.6 at 14:28 UTC. An R3 radio blackout producing significant HF signal fading was observed on the sunlit side of Earth during the height of the flare. Unfortunately for sky watchers anticipating a coronal mass ejection, just like all previous events around 2192 up until this point, a noteworthy CME does not appear evident. The active region continues to move into a geoeffective position. Perhaps our luck will change. Stay tuned. Click HERE for the X1.6 event log.

M8.7 Solar Flare Observed
Region 2192 is back at it again with a strong M8.7 solar flare observed at 01:59 UTC early Wednesday morning. Previous flaring around 2192 the past several days have failed to produce a noteworthy CME. Based on updated SDO imagery using the 193 angstroms channel, no significant coronal dimming, or shock appears evident. More updates to follow once coronagraph imagery becomes available.

Geomagnetic Storm Observed
A cold night in Abisko, Sweden + Clear Skies + Increased Geomagnetic Activity = The Photo Below. Our friend Ruben Roos captured the photo Monday evening (Oct 20) during a period of minor geomagnetic storming. Enhanced geomagnetic activity is being observed at high latitudes due to an enhanced solar wind stream interacting with our geomagnetic field. Sky watchers should remain alert for visible aurora if it is dark outside, especially if you are located around the Arctic Circle.

Another R1 Radio Blackout was observed on Monday as region 2192 continues to churn out solar flares. The latest event initially peaked at M3.0, before rising again to M4.5 at 16:37 UTC. Additional flaring of the moderate to strong variety will be possible as the massive sunspot rotates into a geoeffective Earth facing position.
UPDATE: More flares to report. Region 2192 was reponsible for two more low level M-Flares, including an M1.4 at 19:02 UTC and M1.7 at 20:04 UTC. None of the flares have produced a noteworthy CME up until this point. Will this change? Stay tuned.

Region 2192 continues to evolve as it rotates across the southeast quadrant of the visible solar disk. New spot development is being observed within the central portion of the cluster this morning and this indicates that this complex continues to grow. With a prominent delta magnetic formation present, additional flaring will be very possible. Just how big is this sunspot? Our planet Earth could line up across the cluster at least 8 times over. This upcoming week will see the active region in a better geoeffective position for possible Earth directed eruptions. Attached video using the Helioseismic and Magnetic Imager (HMI) instrument shows the development of AR 2192 over the past 72 hours.

Strong Solar Flare (X1.1)
Region 2192 produced a long duration X1.1 solar flare peaking at 05:03 UTC. Despite the long duration nature and brightness of this event, a noteworthy coronal mass ejection (CME) was not associated with the event. The active cluster of sunspots is not yet in a good position for Earth directed eruptions, but that will change during the next several days. Click HERE for the latest event log.

M4.3 Solar Flare
Higher solar activity to come? Attached image below courtesy of the Solar Dynamics Observatory (SDO) captures an impulsive M4.3 solar flare off the southeast limb peaking at 13:03 UTC Thursday morning. Based on the constant surging off the limb, additional flaring will be possible as the active region begins to turn into Earth view. Stay tuned.

Geomagnetic Storm Observed
An eventful afternoon and evening on Tuesday. In addition to a noteworthy eruption off the east limb, a minor G1 geomagnetic storm (G1) was observed at high latitudes. An enhanced solar wind stream combined with a south pointing Bz contributed to enhanced geomagnetic activity. Many sky watchers reported beautiful aurora displays around the Arctic Circle.

Eruptive Event off East Limb
Good afternoon. An eruption was observed Tuesday afternoon behind the east limb at 18:37 UTC. The event, possibly taking place around old region 2173 from the previous rotation, initially measured M1.1 on the X-Ray scale despite not being directly in view. Solar X-Rays peaked again at M2.2 at 21:05 UTC. We will begin to see source region turn into view over the next few days. A bright coronal mass ejection (CME) became visible in the latest LASCO C3 imagery, but is directed to the east and away from our planet. Image below by the Solar Dynamics Observatory.

SUMMARY: 10cm Radio Burst
Begin Time: 2014 Oct 14 1840 UTC
Maximum Time: 2014 Oct 14 1847 UTC
End Time: 2014 Oct 14 1858 UTC
Duration: 18 minutes
Peak Flux: 1300 sfu
Description: A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.

Filament Eruption and CME
A filament channel located in the southwest quadrant collapsed on Friday and generated a coronal mass ejection (CME). So far the plasma cloud appears to be headed to the west and away from Earth. More details to follow if necessary.

Although not a major spaceweather event, a pair of low level M-Flares were detected around expanding sunspot 2182. The first, an M1.3 flare at 01:43 UTC was quickly followed up by an M1.4 flare at 01:58 UTC early Thursday morning. More flares upcoming? Stay tuned to find out. Image below by the Solar Dynamics Observatory (SDO).

M7.3 Solar Flare Observed
A brilliant looking solar flare was just observed around region 2173 peaking at 19:01 UTC. Attached image below by the Solar Dynamics Observatory (SDO) captures the event off the southwest limb. A coronal mass ejection (CME) was produced, however due to the all too common proximity to the limb, it is directed away from Earth.

Attached video below by the Solar Dynamics Observatory (SDO) captures an impressive prominence eruption early Thursday morning off the east limb. The event generated a coronal mass ejection (CME), now visible in the latest coronagraph imagery. Because this was a limb event, the plasma cloud is directed away from our planet. Still a great looking eruption!

Face of the Aurora
An enhanced solar wind stream has been contributing to beautiful aurora displays around the Arctic Circle the past several days. Ruben Roos up in Abisko, Sweden captured this awesome shot on Tuesday (Sept 30). "It was one of those magic nights again here in Abisko. This display actually looked like it had a little face in it!" With aurora season upon us, more displays will be likely at very high latitudes.
