Strong solar activity in past 72 hours

A strong M-Class flare registering M6.7 took place at 15:46 UTC around active Sunspot 1283. Stay tuned for any further updates.  (SolarHam)On Sept. 8th at 1546 UT, sunspot 1283 unleashed an M6-class solar flare. This continues the active region's 3-day trend of

Solar radio bursts

This week's sharp increase in solar activity has turned the Sun into a radio transmitter. Bursts of shortwave static are coming from the unstable magnetic canopy of sunspot 1283. Yesterday in New Mexico, amateur radio astronomer Thomas Ashcraft recorded some...

X2.1 solar flare took place

A strong X2.1 Class Solar Flare took place at 22:20 UTC Tuesday and was centered around Sunspot 1283. Another CME now looks to have resulted (watch it). A Type II and Type IV sweep frequency event occurred as well as a TenFlare (10.7cm Radio Burst). Proton Levels are

Earth-directed M5.3 solar flare took place

This morning at 0150 UT, sunspot 1283 produced an M5.3-class solar flare. A movie from NASA's Solar Dynamics Observatory shows the flash of extreme UV radiation. Because of the sunspot's central location on the solar disk, the eruption was Earth-directed and a CME

M-class solar flares on northwestern limb of the sun

The northwestern limb of the sun is crackling with M-class solar flares. The source appears to be departing sunspot complex 1280-1286. Coronal mass ejections (CMEs) emerging from the blast site are not Earth-directed. Nevertheless, these flares are having a minor

M3 solar flare took place on Sun's western limb

This morning at 1145 UT, an active region on the sun's western limb unleashed an M3-class solar flare. NASA's Solar Dynamics Observatory recorded the flash of extreme UV radiation:Although the blast site was not directly facing Earth, radiation from the explosion

An enormous filament of magnetism slithering over the sun's northeastern limb

Today, NASA's Solar Dynamics Observatory is monitoring sine wave 400,000 km long.  It's an enormous filament of magnetism slithering over the sun's northeastern limb:One of the wave troughs appears to be passing through the core of sunspot 1282. If so, an eruption

Several sunspots have popped up around the visible solar disk

Sunspots are emerging at several locations around the solar disk, peppering the Earth-side of the sun with active regions. Of particular interest is fast-growing sunspot 1282, shown here in an August 31st snapshot from NASA's Solar Dynamics Observatory:AR1282 has

Expected impact of an incoming solar wind stream

NOAA forecasters estimate a 25% chance of polar geomagnetic activity today in response to the expected impact of an incoming solar wind stream.Solar activity is at very low levels and there is currently no chance for strong solar flares on the earth facing side of

Coronal hole in the sun's atmosphere is spewing solar wind toward Earth

 A yawning dark hole in the sun's atmosphere is spewing solar wind toward Earth. NASA's Solar Dynamics Observatory photographed the opening during the early hours of Aug. 26th: Solar wind flowing from this coronal hole is expected to arrive on Aug. 28-29,

A solar wind stream hit Earth's magnetic field

A solar wind stream hit Earth's magnetic field during the early hours of August 24th, sparking geomagnetic activity around the Arctic Circle. "Bright, fast-moving auroras lit up the sky just after midnight," reports Sean M. Scully, who sends this picture f

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.

New sunspots forming, Venus-directed CME

Yesterday, the Solar and Heliospheric Observatory witnessed a spectacular explosion on the sun that seemed to pass perilously close to Venus.As the movie shows, the CME passed harmlessly. There was no collision, and it wasn't even close. Although Venus seems to be
