We report a possible distance to the star forming cloud Lupus 2
of 360
pc, at least 150 pc larger than previously suggested. Despite the cloud's small
angular size and remoteness this distance estimate is corroborated by
Hipparcos/Tycho data for field stars.
The increased distance changes the mass estimate from 100 to ~600
more like the masses for the other Lupus clouds, but more
interestingly the virial ratio of the two C18O cores in Lupus 2
will be lowered by a factor of 2.4 making Lupus 2 more like Taurus than
the remaining Lupus cores
