We report on an enhancement of X-ray flux from the black hole candidate H 1743-322 detected with MAXI/GSC.
The MAXI/GSC nova alert system triggered the event on 2013 July 31 04:48 (UT).
The 2-20 keV X-ray flux is 33+9-8 mCrab on MJD56504.0-56405.0.
Swift/BAT hard X-ray monitor also shows an increase of hard X-rays.
These results indicate that the source is now entering into a new outburst.
Recent outbursts are reported in, e.g. ATel#2364, #2774, #3842 and #4419.
The interval from the onset of previous outburst (#4419) is 310 days, which is getting longer gradually.
The latest light curves and Image of this source are available at the following URL:
Note that H1743-322 is located near the Galactic center and the Galactic ridge
X-ray emission is not completely removed in the flux of the light curve.
Multi-wavelength observations are encouraged.
