Hi Chris,

It wasn't VLBI, as the baseline between 14m and 26 m antennas is just
100m, so the size of the source didn't matter. With our 16MHz
bandwidth this OH maser would be equivalent to 0.1 Jy continuum source
- not detectable.

Cheers,
Sergei

If you detected an HII region with VLBI I would be suprised (in a
good
way). Are you sure it was not just the OH maser?

Cheers
