C. Guidorzi and R. Margutti (INAF-OAB) report on behalf of the
Swift-XRT team:

Swift re-observed the field of the Fermi-LAT GRB 081024B (Omodei et
al., GCN Circ. 8407) 127 ks after the burst. From 13.5 ks of Photon
Counting mode data, we found that sources 1 and 3 mentioned in our
previous report (Guidorzi et al. GCN Circ. 8410) are still detected
with a count rate compatible with being constant between the two
observations. Although source 2 is no longer detected, we estimate
that the fading is not statistically significant yet.
Further data will allow us to determine the possible fading.
