Solar Eruptions

We have been getting a number of questions and comments lately regarding the possible relationship between solar activity and geological activity, such as earthquakes and volcanoes, so I have decided to look into the matter in more detail. First let […]

Sunspot group, AR12192, released a strong burst of magnetic energy in the form of an X1.1 flare and a surge of solar plasma. The solar flare peaked in the GOES X-ray monitor at 5:01 UT, 10/19/2014. There was no significant […]

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 […]

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 […]

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 active sun is rotating into view, that could mean there is solar fun to come. For the past 2 weeks that sun has been a bit quiet but that is only because the regions of current solar activity were […]

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 […]

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 […]

Just after the X2.2 AR12087 let out an X1.5 flare peaking at 12:52 UT. Here is a snapshot of the event using the SDO/AIA 131 angstrom channel. This shows plasmas with temperatures up to about 10 million Kelvin. http://youtu.be/cV5ccg3n_J0 The […]

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 […]

A huge filament on the southeast of the sun erupted towards the end of June 4. The filament was somewhere between a whopping 500,000 – 1 million km in length. This eruption produced a fairly slow coronal mass ejection that […]

Geomagnetic storms continue while an eruption on the west limb of the sun brings a flare, protons and possibly another CME our way. Solar Eruption The sun erupted with an M3 X-ray flare (NOAA Scale R1-Minor radio blackout) peaked in […]
