Analysis of data in the INTEGRAL archive shows that an outburst
from the recently discovered source IGR J08408-4503 (Atel #813)
occurred on 1st July 2003. The outburst lasted approximately two
hours. During its brightest part (around 20 UT) an average flux
of about 6x10-10 erg/cm2/s was detected in
the 20-60 keV range with the IBIS/ISGRI instrument. The derived
position (RA=130.1900 deg, Dec=-45.07037 deg (J2000),
uncertainty of 2.6 arcmin) is consistent with that reported in
Atel #813 and with the position of the supergiant star HD 74194.
This detection makes it very unlikely that the outburst detected
on May 15th 2006 was a long GRB and supports the interpretation
of IGR J08408-4503 as a new member of the Supergiant Fast X-ray
Transient class.
