Yup, between the flares and geomagnetic activity, the AM band is going
to be fickle at best.   P=(
See the "MW Skywave" section of my "Propagation 101" post, back in May:

Last night (Tue) was absolutely dead, but when I checked when I got up
this morning around 2am, the whole band seemed back up to at least the
low side of "normal", so things must have improved over the last few
hours.   P=)
