Sunspot 1564 unleashed a long duration M1.4 solar flare

Moderate long-duration solar flare measuring M1.4 took place at 17:59 UTC on September 8. It was generated around Sunspot 1564. Another strong flare was recorded about the same time around nearby Region 1562. It is possible that the X-ray flux recorded the cumulative

Sun turns black! Fear not, it's only SDO eclipse season

NASA's Solar Dynamics Observatory (SDO) has moved into its second eclipse season of 2012. September 6, 2012, marks the first day of the SDO Fall Eclipse Season. Today's eclipse lasted 8 minutes and 15 seconds only.  Earth blocks SDO's view of the sun for a period

Geomagnetic storming levels back to normal

Geomagnetic storming reached the G2 (Moderate) level at high latitudes again early today. Bright auroras could be seen around Arctic Circle. It was sparked by one of two coronal mass ejections observed on September 2.  Solar radiation storm levels have returned to

Geomagnetic activity at normal levels while another CME impact expected

NOAA/SWPC reported that the G1 (minor) Geomagnetic Storm has ended with the return of normal solar wind conditions. Currently solar winds blow at speed of 419.1 km/sec. Earthbound proton levels are now below the S1 Minor Radiation Storm threshold and geomagnetic

Minor to Moderate Geomagnetic Storming possible at high latitudes

The Coronal Mass Ejection was caused by the large filament eruption late on August 31st.  Minor to Moderate Geomagnetic Storming will be possible at high latitudes, especially on September 3rd. Solar Radiation Storm levels have increased above the S1 (Minor)

Minor solar radiation storm in progress

High levels of low energetic protons are recorded streaming past Earth causing minor S1 solar radiation storm. Proton event 10MeV Integral Flux exceeded 10 pfu.  Minor impacts on HF radio are possible around polar regions.Elevated solar radiation storm levels are

Spectacular filament eruption, waves of ionization and Sun's polar magnetic field shift for end of August

Spectacular solar filament eruption, thousands of kilometers long, occurred at the Sun's southeast quadrant. Solar X-Ray flux chart values reached almost M-class flare threshold. Huge filament collapsed after almost a week of activity and it resulted in a large C8.1

What is happening with solar observing instruments right now?!

While trying to access SOHO's coronograph data we noticed that the latest LASCO C2 image is updated on August 18 at 13:36 and LASCO C3 at 13:30. Also, SOHO's EIT 304 latest image is from August 17 at 13:19, EIT 195 is from August 16 at 13:13 while EIT 171 and 284 show

Sunspot 1540 produced a long duration M1.0 solar flare

A long duration M1.0 solar flare took place on August 11. 2012. The event started at 11:55, peaked at 12:20 and ended at 12:57 UTC. The source of this solar flare was centered around Sunspot 1540. Plasma was magnetically pulled back in towards 1544 located to the

Long duration M1.8 solar flare erupted from Region 1520

After period of "silence", Active Region 1520-1521 sent another strong solar flare. The event was registered M1.8 solar flare with long duration. Started 12:50, peaked at 17:15 and ended at 18:30 UTC. A very bright Coronal Mass Ejection (CME) could be seen off the

Subsiding geomagnetic storm, all levels are back to normal

The geomagnetic storming started on July 14th through 16th and it is subsiding right now. Geomagnetic storm was triggered by a CME impact on July 14th around 18:00 UTC when strong X1.4 solar flare exploded from Sunspot AR 1520. Conditions at the peak showed Moderate

G2 Geomagnetic storming in progress (Kp=6)

We are still experiencing effects of incoming CME generated from Sunspot 1520 which produced strong X1.4 Solar Flare on Thursday. A Moderate G2 Geomagnetic Storm (KP=6) is in progress right now due to an incoming CME shock. The geomagnetic field has been at active to

Earth-directed CME from X1.4 solar flare expected to impact Earth tomorrow

A powerful solar flare was unleashed from a massive sunspot 1520, blocking high-frequency radio communication in the Northern Hemisphere and producing the potential for auroras. It's the second major solar storm to impact Earth in less than a week.Giant sunspot

Sunspot 1520 harbors energy for X-class solar flare

Sunspot 1520 remains a large sunspot cluster and may produce isolated M-Class and X-class flares. Aside from the pocket of sunspots in the southern hemisphere, the remainder of the visible solar disk is currently spotless. AR1520 stretches more than 140,000 km (11

Increased solar activity - Third M-class solar flare from Sunspot 1515

Solar Activity continues at moderate to high levels. A minor C6 solar flare around Sunspot 1513 was followed up with yet another M-Class flare around Sunspot 1515. The latest blast peaked at M2.0 and the time of the event was 23:56 UTC.This large Sunspot cluster
