I'm not David, but I hope that's OK?  ;-)

= DAvid, can you get an English equivalent of that Danish character?
= I want to put this on the education site. My guess is that it's Ae,
= but I'd like to be sure.

The English equivalent name is "Oersted" (but pronounced with a 'eu'
as in the Dutch word 'deur').

I'm almost sure the first letter is normally written as an 'o' and 'e'
joined to form one character, i.e. the right side of the o touches the
left side of the e.

"Oersted" is the old unit for measuring the strength of a magnetic field
and this name matches perfectly with the mission of the satellite, which
is to measure the earths magnetic field.

Hope this helps. ;-)
