The Cave's Solar Update with Current LASCO C2 and LASCO C3


Sunspot 1283 which was the source of numerous M-Class and X-Class flares is now rotating onto the western limb and within the next few days will be out of direct earth view. This region did produce a couple of Coronal Mass Ejections, one of which did impact earth on Friday and triggered a Geomagnetic Storm.

There will most likely be new Sunspot regions rotating into view on the eastern limb.

Big Sunspot 1289 continues to produce C-Class flares and could soon produce an M-Class event.

Elsewhere, Sunspot 1291 looks to have already faded but at the same time a few new regions have popped up in the northern hemisphere.

The Large Angle and Spectrometric Coronagraph (LASCO) is one of a number of instruments aboard the Solar and Heliospheric Observatory satellite (SOHO). LASCO consists of three solar coronagraphs with nested fields of view.
