Sunspot regions
The only group of interest is sunspot group 2164 which developed a weak magnetic delta structure within it's trailer spots. It is however a relatively small sunspot group and M-class flaring remains unlikely, but not entirely impossible. One thing to note is that this sunspot region is already rotating towards the west-limb so any future eruptions will likely be directed away from Earth.

Other than sunspot region 2164 there are not really any other sunspot groups on the earth-facing disk worth mentioning right now. There is a large coronal hole facing Earth right now on the Sun's southern hemisphere but it is likely at a latitude too high to really have any influence on Earth. We expect quiet space weather conditions both on the Sun and at Earth for at least the coming three days, especially now that also sunspot regions 2157 and 2158 (source of the X1 solar flare) are leaving the earth-facing solar disk.
