During a recent INTEGRAL public observation of Musca region, performed
between 2015-12-11 17:54 and 2015-12-12 12:54 (UTC),
renewed activity from the transient X-ray pulsar IGR J11435-6109 has
The 22-60 keV IBIS/ISGRI flux corresponds to (10+/-1) mCrab with an
effective exposure time of 18 ks.
The source was within the field of view of JEM-X instruments for a
net exposure time of 36 ks. In the combined JEM-X1 and JEM-X2 mosaic, it
was detected at a flux level of 3.8+/-0.4 mCrab and 3.7+/-1.1 mCrab in the
3-10 keV and 10-25 keV energy ranges, respectively.
We note the time of this detection is consistent with the epoch of
expected maximum flux, assuming the ephemeris information reported in
