Following the MAXI/GSC alert of a possible new transient named MAXI J0709-159 (ATel #15178), NICER performed multiple pointings to localize the source position beginning at 2022-01-25T13:44 (UTC). Starting from the nominal coordinates reported by MAXI, NICER performed a series of offset pointings with 42 s exposure for each. A preliminary source position was obtained at
R.A. = 107.392 deg
Dec = -16.108 deg
(J2000), with 3 arcmin radius uncertainty set by the NICER non-imaging field of view.
The averaged X-ray flux is about 10 mCrab in the NICER energy band (0.2 - 12 keV).
Further NICER observations of this source are underway. Additional multi-wavelength observations are strongly encouraged.
NICER is a 0.2-12 keV X-ray telescope operating on the International Space Station. The NICER mission and portions of the NICER science team activities are funded by NASA.
