CME impact, sunspot region 2205, STEREO B
This night around 01:46 UTC we saw the arrival of the X1.6 coronal mass ejection. It was slightly stronger and earlier than expected. In this article we take a look at the stats and what kind of geomagnetic conditions to expect in the hours ahead. We also take a look at sunspot region 2205 which was the source of numerous strong solar flares during the past few days. What is left of sunspot region 2205 and can we still expect activity from it? The STEREO mission team has also came out with a very detailed report regarding the loss of contact with STEREO Behind. It is an interesting read for those who wish to know more about STEREO Behind's current status.
