Starting the Day with a Flare, Protons and a Geomagnetic Storm

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 […]

Geomagnetic Storm and Aurora from Valentine’s Weekend CME

A CME from February 16, 2014 has impacted Earth. The CME’s magnetic structure was such that it stirred things up in the magnetosphere.   A significant interplanetary shock detected by ACE at L1 at 3:10 UT, February 19, 2014.   The […]

A Whole Lot Happening on the Sun – In Many Types of Light

The sun has been really active lately. SDO gives us an amazing view of this activity in many different wavelengths of light. This also shows us the sun’s atmosphere in many temperatures ranging from ~4500 Kelvin or 7600 degrees Fahrenheit […]

Total Solar Eclipse in the South Pacific – November 13/14, 2012

  A total eclipse of the Sun will be visible on November 13/14, 2012 in a narrow path across the southern hemisphere. The Moon’s umbral shadow starts in northern Australia following a path across the South Pacific Ocean without crossing […]

Earth Bound CME Predicted with X1 Flare Event

Possible Moderate to Severe Geomagnetic Storm Sunspot group, AR11520, produced an X1.4 solar flare, peaking in the NOAA GOES X-ray monitor at 16:52 UT (12:52 EDT). This flash of electromagnetic radiation temporarily altered the upper atmosphere changing its ability to […]

Unidentified Sun Object is Identified! A Little Black Spot on The Sun Today

On March 12, 2012, Sunsflare posted a video asking if anyone could identify a circular object seen in SDO coronal images. The video was also posted on Facebook with the same question posed. I answered the question on Facebook but […]

Lovejoy’s Last Day – Unprecedented Multi-spacecraft Observations of a Comet’s Demise (Surprise filled update 12/16/2011)

UPDATE: Lovejoy survived despite most predictions to the contrary! Check out the videos below. A sungrazing comet called Lovejoy is near what will surely be its end. Sungrazers melted by the Sun is not really new. In fact, SOHO has become […]

Connecting the Spots (SDO Pick of the Week – May 20, 2011)

An extensive series of arcs, observed in profile, can be seen making a long distance connection between two active regions (Mar. 15-17, 2011). As SDO observed in extreme ultraviolet light, a series of magnetic field lines generated a well-defined pathway […]

Epic Solar Filament Eruption from Dec. 6, 2010 Seen by STEREO

A very long solar filament that had been snaking around the Sun erupted (Dec. 6, 2010) with a flourish. STEREO (Behind) caught the action in dramatic detail in extreme ultraviolet light of Helium. It had been almost a million km […]

Another Lunar Transit of the Sun Seen by SDO

As expected SDO experienced another lunar transit on November 6, 2010. This time the moon crossed the southern hemisphere moving from the south pole towards the northeast (left side) edge of the sun. The transit took about 30 minutes and […]

A Solar Eruption as the Earth Blocks SDO’s View of the Sun

A filament erupted in the NE area of the sun. The eruption was observed by SDO and the associated Halo CME was seen by SOHO's C2 and C3 coronagraphs. SDO is currently in eclipse season so during this event the earth moved between SDO and the sun, moving across the sun for a few minutes.
