A CME from 11/9/2012 shown in a LASCO C2 image (left) and a difference image (right) made by subtracting the image just prior. The leading edge of the CME is denoted by the yellow arrow.

A CME is coming our way! A slow (only ~570 km/s  Type-C), faint CME was detected by LASCO and STEREO around 15:24 UT 11/09/2012 and it is heading in the direction of Earth.

The CME from 11/09/2012 was observed in STEREO Ahead COR2. The CME is denoted by the yellow arrow.

The CME from 11/09/2012 was observed in STEREO Behind COR2. The CME is denoted by the yellow arrow.

Computer models indicate that the leading edge will reach Earth 11/12/2012 around 23:00 UT (+-7 hrs). The impact is expected to be minor with the possibility for a minor geomagnetic storm. This means not a very significant event but those at high latitudes may get an auroral show.

Here is the computer model from the NASA Goddard Space Weather Research Center showing the CME on its journey through the solar system to Earth.

  1. Since I’ve had 5 foot operations in the last 2 1/2 years ,I have been following the Sun on the internet quite a involved process that you go through to keep us informed,With the “holes in our magnetosphere” Is it going to withstand a large X-class flare…We have been warned about a rather large one around the 17th-19 th of December.(This was on the SOLARWATCHER .NET) website any insight would be great
