A new look at sunspots
NASA’s extensive fleet of spacecraft allows scientists to study the Sun extremely close-up – one of the agency’s spacecraft is even on its way to fly through the Sun’s outer…
NASA sun data helps new model predict big solar flares
Using data from NASA’s Solar Dynamics Observatory, or SDO, scientists have developed a new model that successfully predicted seven of the Sun’s biggest flares from the last solar cycle, out…
NASA’s SDO Sees New Kind of Magnetic Explosion on Sun
from NASA Dec. 17, 2019 NASA’s Solar Dynamics Observatory has observed a magnetic explosion the likes of which have never been seen before. In the scorching upper reaches of the…
Sun spotless for 33 days straight – airline travelers getting dosed with up to 70 times more radiation [than at sea level]
Are we in a solar grand minimum? We’ve seen this before, but now predictions are for an extremely weak solar cycle ahead. Today is the summer solstice in the northern…
From AGU: comet ISON's struggle of Fire and Ice
San Francisco – After a year of observations, scientists waited with bated breath on Nov. 28, 2013, as Comet ISON made its closest approach to the sun, known as perihelion.…
Comet ISON appears to be toast – goes "poof" in video, then comes back to life
Note: See updates below for the ISON ISOFF ISON nature of this comet that has everybody guessing. Picture at right also updated to reflect the new “zombie” status of this…
Sun produces four X-class flares in two days
Above: note the four separate events in the last two days – from the WUWT Solar Page (From NASA’s Spaceweather.com) When the week began, the sun hadn’t unleashed an X-flare…
Three years of the Sun in three minutes
Spectacular three year time lapse video from the Solar Dynamics Observatory In the three years since it first provided images of the sun in the spring of 2010, NASA’s Solar…
Our current solar cycle 24 – still in a slump – solar max reached?
Have we hit solar max? NOAA’s SWPC recently updated their solar metrics graphs, and it seems to me like we may have topped out for solar cycle 24. There doesn’t…
Solar cycle 24 continues weakly, perhaps weakest of the space-age
NOAA SWPC has updated their plot page of solar metrics, and the slump continues. At spaceweather.com Dr. Tony Phillips writes: SO THIS IS SOLAR MAXIMUM? Forecasters have long expected the…
The sun – still slumping
The latest solar cycle update graphs have been released by the NOAA SWPC today, and the anemic cycle 24 continues: The current count isn’t keeping up with the prediction line…
Solar corona revealed in super-high-definition
From the Harvard-Smithsonian Center for Astrophysics Today, astronomers are releasing the highest-resolution images ever taken of the Sun’s corona, or million-degree outer atmosphere, in an extreme-ultraviolet wavelength of light. The…
Still waiting for the CME from the X Class flare
Spaceweather.com writes: (link mine) The CME launched toward Earth by the July 12th X-flare has not yet arrived. However, we are still within the forecast window set by analysts at…
X-Class solar flare blasts CME directly at Earth
Large sunspot Group AR1520, seen below just right of center, was pointed directly at Earth when the flare occurred. The GOES Xray Flux spike hit X 1.4, just barely an…
Time lapse video of Venus transit seen from SDO
Thanks to reader Mike McMillan for pointing this awesome HiDef video out. It is the best I’ve seen.
Transit of Venus today may reveal the "Mysterious Arc of Venus"
From Dr. Tony Phillips Science at NASA When Venus transits the sun on June 5th and 6th, an armada of spacecraft and ground-based telescopes will be on the lookout for…
Whole lotta watts added to the atmosphere
I loved the way James Russell described CO2 molecules as “natural thermostats” Solar Storm Dumps Gigawatts into Earth’s Upper Atmosphere A recent flurry of eruptions on the sun did more…
Biggest solar storm since 2005
It is being called by WaPo “The Biggest solar storm since 2005“. The sun erupted late on January 22nd, 2012 with an M8.7 class flare. The Solar Dynamics Observatory captured…
Comet Lovejoy survives a brush with Sol
From Physorg.com Comet Lovejoy was only discovered a couple of weeks ago. It was supposed to melt as it came so close to the sun that the temperatures would hit…
Solar activity on the upswing, big sunspot rotating into view is producing x-class solar flares. Large CME expected soon, may hit earth.
From Spaceweather.com: New sunspot 1302 has already produced two X-flares(X1.4 on Sept. 22nd and X1.9 on Sept. 24th), can another be far behind? NOAA forecasters put the 24-hour probability at…
SDO sees 'Dark Fireworks' on the Sun
From Science@ NASA: 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…
Scientists Prove Existence of 'Magnetic Ropes' that Cause Solar Storms
Seems like GMU doesn’t stop, waiting for Dave Clarke and John Mashey to launch the next copygate volley. Here’s some interesting research. FAIRFAX, Va., June 15, 2011—George Mason University scientists…
Sol is finally waking up
Let’s hope he does get out of the wrong side of the bed. The current sunspot count and 10.7 cm radio flux have increased in the latest NOAA SWPC graphs,…
