Siegel (PSU) reports on behalf of the Swift team:\n\nSwift performed a follow-up observation of the possible X-ray afterglow of\nthe BAT-detected GRB 130306A (Siegel et al., GCN Circ. 14287).  A 5 ks\nobservation took place on 14 March 2013, eight days after the burst.  \nThe reported source faded by at least a factor of three, from .009\ncounts s^-1 (observed flux 4.2 x 10^-13 erg cm^-2 s^-1) to an upper\nlimit of of .003 counts s^-1 (observed flux 1.5 x 10^-13 erg cm^-2 s^-1).\nWe therefore confirm that this was the X-ray afterglow of GRB 130306A.",
