The MAXI/GSC detected an enhanced X-ray emission from a position
consistent with 4U 0142+61 during the scan transit of 53 seconds
centered at 2011-07-29 11:23:15 (UT). The scan started 214 seconds
later than the Swift/BAT trigger of a short burst from this source
(GCN 12209). The GSC light curve during the scan transit showed no
significant spiky structure and the averaged X-ray flux was 69 +- 16
mCrab in the 4-10 keV band. The source flux had been below the GSC
detection limit of typical 20 mCrab for each scan until the previous
scan transit (92 minutes before) and also since the next transit (92
minutes later).
