X class solar flare ejection may hit Earth with solar storm
From the WUWT Solar Reference page, an X 1.2 event has occurred: From NASA Spaceweather: Giant sunspot AR1944 erupted on Jan 7th at approximately 1832 UT, producing a powerful X1-class…
Sunspot group AR1890 takes direct aim at earth
May produce a dangerous X-class flare that could directly impact Earth Steve Davidson writes: Right now, today, one of the largest sunspot groups of Cycle 24 – AR1890 – is…
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…
A misinterpreted claim about a NASA press release, CO2, solar flares, and the thermosphere is making the rounds
I loathe having to write this story because I truly dislike giving any attention to the people who are known as the “slayers” from the “Slaying the Sky Dragon” book.…
New study finds that a Carrington class solar event could cause global cooling of more than 3C
A paper recently published in Atmospheric Chemistry and Physics finds that “a solar proton event, if it took place in the near future with an intensity similar to that ascribed…
X class flare CME arrival updated
From Spaceweather.com The CME launched toward Earth by yesterday’s X-flare is moving faster than originally thought. Analysts at the Goddard Space Weather Lab have revised their forecast accordingly, advancing the…
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…
'Doppler radar' for solar storm detection
Rice researcher part of team that used Doppler shifts to ID phenomenon; may help predict space weather HOUSTON – (July 2, 2012) – Doppler measurements that help track storms on…
Sunspot AR1476 takes aim on Earth
From Spaceweather.com NOAA forecasters estimate a 75% chance of M-class solar flares and a 20% chance of X-flares during the next 24 hours. Any eruptions are likely to be geoeffective…
"firecracker" sunspot turning towards earth – possible large solar flares
Sunspot AR1476 may have some surprises for us in the coming days, and I hope it isn’t a Carrington type event. It has already launched two CME’s yesterday. From NASA’s Spaceweather.com:…
Potential for large solar flares and CME's may be with us again soon
Readers may recall my reports on the CME’s from massive sunspot group 1429, seen below. It seems the sunspot group continues to live, and has unleashed another massive Coronal Mass…
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…
Recent solar flare seen bombarding Earth with gamma rays
From the “Oh noes it’s Radiation” department, Dr. Leif Svalgaard points out we all got a gamma ray bath on that recent big solar flare. I wonder how many Banana…
Solar storm continues, geomagnetic storm and auroras expected
We have about three hours to go for the expected arrival time of the CME at 0625 UTC/1025 PM PST. Proton flux remains high as do other indicators. Additionally another…
Major x class solar flare
Blogging from my phone Check WUWT Solar Reference Page Updated: It was an X1.7 class eruption, it does not appear to be headed towards Earth. JTF
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…
Big CME headed toward Earth
From Spaceweather.com : Active sunspot 1401 erupted yesterday, Jan. 19th around 16:30 UT, producing an M3-class solar flare and a full-halo coronal mass ejection (CME). The Solar and Heliospheric Observatory…
Big CME hits earth, low latitude auroras possible
From the Rice University Spaceweather listserv Our space weather alert system is in level yellow, and the CME input of energy to the Earth’s magnetosphere still continues. So, if you…
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…
