Solar monitors are offline due the superstorm impact on US East Coast
October 30, 2012
All eyes are focused on Sandy and its epic impact on US East Coast. All of you that are focused also on space weather events, probably have noticed that there is blackout of solar observing data providers. The SDO, SOHO, STEREO and helioviewer sites are all offline. Websites are being taken offline for immediate access during the east coast storm. Goddard Space Flight Center is in the metro DC area, which will experience significant storm impact.
However, all solar data is still being recorded. Current space weather conditions are still being monitored by the GOES spacecraft.
X-ray levels recorded by NOAA/SWPC at Boulder, Colorado are showing quiet conditions but latest few days we could see some activity. Large solar flares could be observed. However, although they looked spectacular, there were no M-class or even bigger C-class recorded on its charts.
The largest and only event recorded on October 29 was a B6 flare at 03:02 UTC from Region 1596. Regions 1601 and 1602 were numbered on October 29. No Earth-directed CMEs were detected during the reporting period.
A long duration C-class flare was observed beyond the southwest limb on Sunday morning near old region 1594 but generated plasma was not Earth-directed.

- Moderate solar activity – M2.3 solar flare, G2 geomagnetic storm Moderate solar activity has been observed during the past 24 hours. M2.3 solar flare was triggered by an Active Region behind the eastern limb around 11:17 UTC. Three C flares occurred during the day producing two CMEs, observed by LASCO C2/C3 coming off the east limb early in the day, however neither are expected to be geoeffective. Geomagnetic storming reaching the G2 (Moderate) level was observed overnight with the arrival of expected October 5 CME. At G2 level high-latitude power systems……
- Solar activity at low levels with possible Earth-directed CME… Solar activity was at low levels for the past 24 hours and X-Ray flux plot shown merely C-class threshold. However, a prominence eruption was observed north of Region 1600. A bright CME was observed in STEREO Ahead COR 2 imagery at 18:24 UTC on October 27. Latest STEREO Ahead COR2 images indicate that this CME may be Earth directed. SIDC reports that a halo or partial-halo CME was detected. SpaceWeather.com reports that filament of magnetism snaking around the……
- Strong solar activity causing severe geomagnetic storm High-latitude sky watchers should be alert for auroras. A strong (Kp=7) geomagnetic storm is in progress. Earth’s magnetic field has been strongly disturbed since approximately 1300 UT on Sept. 26th when a CME hit our planet. The impact strongly compressed the magnetosphere, exposing geosynchronous satellites to solar wind plasma, and ignited auroras around both poles. Particles that were blasted from the sun by a huge eruption over the weekend have reached Earth, causing geomagnetic storms……
- Spacecraft sees solar storm engulf Earth For the first time, a spacecraft far from Earth has turned and watched a solar storm engulf our planet. The movie, released today during a NASA press conference, has galvanized solar physicists, who say it could lead to important advances in space weather forecasting. The movie shows a CME swelling into an enormous wall of plasma and then washing over the tiny blue speck of Earth where we live. CMEs are billion-ton clouds of solar……
