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

Huge defunct satellite to plunge to Earth

Heads up! That's the word from NASA on Sept. 7  given the impending re-entry of a 6.5-ton satellite through Earth's atmosphere. The huge Upper Atmosphere Research Satellite (UARS) is expected to re-enter Earth's atmosphere in an uncontrolled fall in late September or

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

Some facts and figures about Comet Elenin

2010 X1 (Elenin) is apparently disintegrating. It faded dramatically after a solar flare on August 20. Images at the end of August revealed a spreading, more diffuse coma. It will likely continue to fade and become more diffuse in the opening days of the month. It

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

What is happening with International Space Station

While some may dismiss such claims as hype, there is a real fear among NASA officials that, should the orbiting space station need to be abandoned, the risk for a catastrophic failure greatly increases. The situation arose when Russia’s Soyuz rocket, carrying

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

Comet Elenin self-destructs?

Whenever astronomers discover a comet headed inbound toward a close encounter the Sun, there's always buzz among observers about how bright it might get. That was certainly the case last December, when Comet Elenin (C/2010 X1) made its debut. Many hoped
