The Carrington Flare

The first observations of a solar flare On September 1st, 1859, (151 years ago today) a 33 year old astronomer called Richard Carrington, working at an observatory in Surrey, England, went about his daily duties of sketching the peculiar dark […]

X17 Solar Flare and Solar Storm of October 28, 2003

On this day in 2003 (October 28), the Sun unleashed one of the largest and most geoeffective solar storms of the modern age (and consequently, one of the most studied). The eruption was part of what became known as the […]

NASA’s Magnetospheric Multiscale (MMS) Mission: Studying magnetic fields around the Earth

By looking close to home, NASA’s newest mission with provide a window to the universe. Countdown to MMS Launch The Magnetospheric Multiscale, or MMS, mission was created to study how magnetic fields around Earth interact with activity from the sun. The […]

AR12158 Gives Away an X-flare and CME

AR12158 produced an X1.6 flare along with a coronal mass ejection. The flare peaked in X-rays at 17:45 UT. 18:20 UT (9/11/2014) – This movie is a difference movie created by Dr. Nariaki Nitta (@halocme) from the Lockheed Martin Solar and […]

A Dazzling Eruption Captured by STEREO Behind

SDO and SOHO were not the only spacecraft to capture the spectacular eruption off the East (left) limb of the sun on August 24, 2014. The M5.9 flare (at 12:17 UT) from AR 12151 was seen by the STEREO SECCHI […]

Giant Filament Staring at Earth

High above the solar surface in the hot million+ C solar corona sits a giant filament of cooler (~50,000 C), denser material, both supported and restrained by solar magnetic fields. If this filament should become unstable as they sometimes do […]

AR12113 Erupts with an M6.5 Flare

03:11 UT – Space Weather researchers at NASA/GSFC have determined the CME may affect Mars and Spitzer as well as possibly glance Earth. The CME has an estimated speed of 725 km/s. Below is a computer model showing the CMEs […]

The Sun is really, really big!

A giant filament on the eastern edge of the sun really puts the size of our star, Earth and the planets into perspective. This structure of solar plasma, a billion plus tons of 80,000 degree Fahrenheit material, sits high above […]

A CME Impact at Earth – Maybe?

NOAA active region AR12087 began making its activity apparent in SDO well before it became visible on the Earth facing solar disk. Solar flares from the region became visible in the first week of June. On June 10, the region […]

Geomagnetic Storm and Aurora from Brush with CME

High latitude observers treated with spectacular aurora June 8 and June 9th. The CME that glanced Earth’s magnetosphere on June 7 started a minor geomagnetic disturbance just after the impact that grew into a G1 then G2 level geomagnetic storm […]

CME from Filament Eruption Brushes Earth

The CME is here! As predicted the CME from the June 4 filament eruption impacted Earth’s magnetosphere around 16:30 UT with a glancing blow and created a minor geomagnetic disturbance. The plot above shows the solar wind measured by the ACE spacecraft, […]

Possible Glancing Blow CME

The slow CME produced by the giant filament eruption from June 4 could give Earth a glancing blow. The impact should be very weak but there could be a minor geomagnetic enhancement on June 7. High latitude aurora watchers may […]
