Yesterday's M-flare producing active region rotates into view
Saturday, 30 May 2020 13:05 UTC
The sunspot region that was responsible yesterday for what could be the first M-class solar flare of Solar Cycle 25 has now rotated into view.
There isn't much good news to report however. There is only one small sunspot visible surrounded by faculae which indicates that this sunspot region has been in decay. More M-class activity from this sunspot region seems unlikely.
Were also seeing a slight increase in geomagnetic activity at Earth. The interplanetary magnetic field strength is moderate at the moment and this morning the Bz managed to dip below -10nT at times. This could be a weak glancing blow from a coronal mass ejection that left the Sun a couple of days ago. The Kp index maxed out at 3 but it does not seem likely that we will reach active geomagnetic conditions (Kp4) at the moment as the Bz turned northward. Do follow the data live on our website in case conditions change in the hours ahead.
