& INAF-OAR), V. D'Elia (SSDC & INAF-OAR), J.A. Kennea (PSU), D.N.
Burrows (PSU), M. A. Williams (PSU), J.P. Osborne (U. Leicester) and
P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:

Swift-XRT has performed follow-up observations of the MAXI-detected
burst GRB 241213B in a series of observations tiled on the sky.  The
total exposure time is	2.2 ks, distributed over 7 tiles; the maximum
exposure at a single sky location in the tiling was 822 s. The data
were collected between T0+54.1 ks and T0+60.2 ks, and are entirely in
Photon Counting (PC) mode. 

One uncatalogued X-ray source has been detected, it is below the RASS
limit and shows no definitive signs of fading. Therefore, at the
present time we cannot confirm this as the afterglow. Details of this
source are given below:

Source 1:
  RA (J2000.0):  331.7177  =  22:06:52.25
  Dec (J2000.0): +4.0971  =  +04:05:49.6
  Error: 9.0 arcsec (radius, 90% conf.)
  Count-rate: 0.0185 [+0.0089, -0.0068] ct s^-1   
  Distance: 1169 arcsec from MAXI position.
  Flux: (1.21 [+0.59, -0.44])e-9 erg cm^-2 s^-1 (observed, 0.3-10 keV)

The results of the XRT-team automatic analysis of the tiled XRT
observations, including a position-specific upper limit calculator, are
available at https://www.swift.ac.uk/xrt_products/TILED_GRB00130.
