Abstract (from CDS):

At 2011-05-08 04:21 UT (MJD=55689.18125), the MAXI/GSC alert system triggered a new X-ray transient at the position:

(R.A., Dec) = (+235.788 deg, -56.421 deg) = (15 43 09.1, -56 25 16) (J2000)

with a systematic uncertainty of 0.2 deg.

The 2-20 keV X-ray flux from the source has increased since 2011-05-07,

reaching 21±5 mCrab on average at scan transits from 2011-05-07 13:07

to 2011-05-08 04:21. The source is too faint for the MAXI/GSC to detect any significant variability.

Its energy spectrum, however, tends to become softer after the detection.

There is no known X-ray source within the error circle, and no bright sources

are found on archival ROSAT all-sky survey images. We tentatively refer this transient as MAXI J1543-564. Follow-up observations are strongly encouraged.
