Abstract
During INTEGRAL Galactic Bulge monitoring (ATel #438; Kuulkers et al. 2007, A&A, 466, 595) observations performed on April 16, 2012, between 5:12 and 8:53 (UTC), the twin X-ray monitor JEM-X detected an X-ray burst starting at UTC 8:37:09 from the position:
RA= 271.020°
DEC=-34.344°
with an error radius of 1.2' (at 95% confidence level).
This position lies only 57'' from the unclassified X-ray source 1RXS J180408.9-342058, and we tentatively associate the origin of the burst with this source.

The burst peak flux reaches 3.2 Crab (9.3 ×10-8 erg/cm2/s) in the 3-25 keV band.
