Late flowers on Mammmmillaria Polythele

[willow]

Good Evening all
We havehad an exceptionally warm autumn and early winter, but have haa spell of very cold weather and my mamm. Polthele is still flowering although not as profusely as it did in the summer! I wonder if it has gone into dormancy yet Im sure my other cacti have and they have had no water since the end of September all of them even the Mamm.
