Sunspot AR1261 unleashed a brief but strong M9-class solar flare on July 30th at 0209 UT. NASA’s Solar Dynamics Observatory recorded the flare’s extreme ultraviolet flash:Because of its brevity, the eruption probably did not hurl a substantial CME toward Earth,
Sunspot 1260 has developed a delta-class magnetic field that harbors energy for powerful X-class solar flares. Such an eruption today would be Earth-directed as the sunspot turns to face our planet.Sunspot 1260 is leading a parade of big sunspots across the solar
An M1.1 Solar Flare took place at 16:07 UTC Wednesday and was centered around Sunspot 1260. Click HERE for a still image captured by the GOES SXI. More to follow.iSwacNOAA SWPC Space Weather NowLatest Alert: Jul 27 1214 UTC CONTINUED ALERT: Electron 2MeV
After more than a week of quiet, solar activity is picking up. NASA’s Solar Dynamics Observatory is monitoring two big sunspot groups now emerging over the sun’s eastern limb. Click on the image to view a 40-hour movie.The leading sunspot group, AR1260, is crackling
Mysterious and gigantic jets of lightning that shoot up to near the edge of space have now been observed in unprecedented detail, revealing just how much charge they pack and how they form. More than 50 miles (80 kilometers) above Earth's surface, extreme…
Analysts at the GSFC Space Weather Lab report elevated levels of energetic electrons around Earth. ("GOES 13 > 0.8 MeV integral electron flux is above 105 pfu.")This is caused by the high-speed solar stream now blowing around our planet. Spacecraft wit
The scientific process, as any experienced researcher can attest, provides a kind of road map through the forest of the natural world. By developing hypotheses and designing methods by which to test them, we use the scientific process to make the abstract world more
The solar wind is at elevated levels and this may stir up minor activity at very high latitudes.Solar windspeed: 622.5 km/secdensity: 3.8 protons/cm3Planetary K-indexNow: Kp= 5 storm24-hr max: Kp= 5 stormInterplanetary Mag.
On June 7, 2011, Earth-orbiting satellites detected a flash of X-rays coming from the western edge of the solar disk. Registering only “M” (for medium) on the Richter scale of solar flares, the blast at first appeared to be a run-of-the-mill eruption- that is, until
The CME was not squarely Earth-directed and is not traveling at great speed, only minor geomagnetic storming is expected when the cloud arrives. A coronal mass ejection (CME) that billowed away from sunspot 1247 on July 9th could hit Earth's magnetic field on…
