 Hello Sebastian,

Following  will work.

 $ ~ ^\circ   M$

Note that ~ is   just dummy base so that one can have `o' as superscript.

To reduce spacing between `o' and `M' one can use \! in addition, then
code will look like this.
$ ~ ^\circ \! M$

I hope there must be some other command which can directly generate
similar output.

Regards,
