E. O. Ofek (Caltech) report:
I note that the IPN coordinate constraints of GRB 070201 (Golenetskii et al.; GCN 6088)
do not contain the position of the galaxy M31 (cf. Perley & Bloom; GCN 6091).
The ecliptic latitude of M31 is 33.3 deg, while the Konus/Wind satellite
constrained the ecliptic latitude of this burst to lay between +60 and +90 deg.
However, the relatively massive/nearby spiral galaxy NGC 5985 (distance of ~40
Mpc) satisfies the IPN constrains.
A plot of the galaxy position and IPN annulus is in:

I further note that the total area within the IPN constraint is about 8 sq deg.
