Big Winter Mesospheric Echoes break out

Very strong high latitude polar mesospheric winter echoes have broken out in the past 24 hours.  I wasn't active on the bands today, so I wonder if there was any 6m or higher HF enhancement?

The second plot shows the situation 24 hours later, with an intensification in echoes.
