We report the discovery of a single X-ray burst from the direction of
the anomalous X-ray pulsar 1E 1048.1-5937, in data from the Rossi X-ray
Timing Explorer Proportional Counter Array, obtained on June 29, 2004.
The burst is present in all operational PCUs. A preliminary inspection
shows that the burst properties are qualitatively similar to the two bursts
observed in 2002 from this direction by Gavriil, Kaspi & Woods (2002, Nature,
419, 142). This may indicate that the source is entering a burst-active
phase.
More information will be posted as it becomes available.
Rossi X-ray Timing Explorer and coordinated Chandra Target-of-Opportunity
observations are planned.
Observations at other wavelengths, especially infrared, are encouraged.
