K. Hurley and J. Goldsten, on behalf of the MESSENGER NS GRB team, 

S. Golenetskii, R. Aptekar, E. Mazets, V. Pal'shin, D. Frederiks, 
D. Svinkin, and T. Cline on behalf of the Konus-Wind team,

W. Boynton, C. Fellows, K. Harshman, H. Enos, and R. Starr, on
behalf of the GRS-Odyssey GRB team,

Y. Terada, T. Murakami, and K. Makishima on behalf of the Suzaku WAM team,

the Swift-BAT team,

E. Del Monte, I. Donnarumma, Y. Evangelista, M. Feroci, I. Lapshov,
F. Lazzarotto, and M. Marisaldi, on behalf of the AGILE Team, and

V. Connaughton, M. S. Briggs, C. Meegan, and V. Pelassa, 
on behalf of the Fermi GBM team, report:

GRB 130502B (von Kienlin et al., GCN 14530, Kocevski et al., GCN 14532,
Golenetskii et al., GCN 14542, Hurley et al. 14546) was also observed by 
Odyssey.  Using Odyssey data reduces the size of the previous error box
by about a factor of two: 

              RA(2000)                    DEC(2000)

CENTER:  66.714= 4 h 26 m 51 s      71.066= 71 d 03 ' 58 "
CORNERS: 66.893= 4 h 27 m 34 s      71.032= 71 d 01 ' 55 "
         67.092= 4 h 28 m 21 s      70.975= 70 d 58 ' 29 "
         66.334= 4 h 25 m 20 s      71.156= 71 d 09 ' 22 "
         66.535= 4 h 26 m 08 s      71.100= 71 d 05 ' 59 "

The area of this box is about 8 square arcminutes, and it still contains the
Swift-XRT source (Melandri et al., GCN 14540).  A new map has been posted at
ssl.berkeley.edu/ipn3/130502

Some improvement in this error box is possible.
