NASA observes 'significant solar flare' on the sun that thankfully missed Earth
NASA’s Solar Dynamics Observatory, has sent back pictures of a massive, X-class solar flare. The X-class flares are the strongest, and this one received an X2.7 rating. It wasn’t pointed…
Massive X class flare erupts from the sunspot 2192
As we previously mentioned on WUWT, the Sunspot 2192 which is as large as Jupiter had the potential of hurling large solar flares toward Earth. According to NASA’s spaceweather.com “Giant…
Solar flare danger – massive sunspot the size of Jupiter takes aim at Earth
The potential for a massive solar flare directed at Earth is looming large. An SDO/HMI view of the visible sun showing the largest sunspot of solar cycle 24, AR12192. Image…
Dramatic video – imagine Earth in the path when the sun goes 'splode'

Sailing on the Solar Wind
Guest Post by Willis Eschenbach The lack of cycles in the solar wind isn’t surprising when you analyze this paper. There is very little sign of any kind of annual…
Solar Cycle Update – M class flare, little change in metrics, solar dynamo still slumping
From NASA Mid-level Solar Flare Erupts from the Sun May 8, 2014 The bright light on the left side of the sun shows an M5.2-class solar flare in progress on…

The Solar storm has arrived – initial impact weaker than expected
From NASA: Spaceweather: As expected, a CME hit Earth’s magnetic field on Jan. 9th (around 20:00 UTC or 3 p.m. EST). Although the initial impact was weaker than expected, geomagnetic…
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…

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…
