Arne Henden quotes a more exact position for this object, based on
Shawn Dvorak's images, which can be used to update the below
galnovae.dat entry. Note also that in the end this position places it
slap bang on top of the ATEL 1282 proposed USNO A2.0 progenitor, which
is also listed in 2MASS :-

Henden/Dvorak Nova position : 07 05 42.51 -38 14 39.3

2MASS progenitor position : 07 05 42.50 -38 14 39.4

both J2000
