The source was found in its highest level of X-ray activity yet detected, a factor $\\sim 23.5$ higher in 2--10 keV flux than the historical minimum. NGC 2992 is known to exhibit X-ray flaring activity on timescales of days to weeks, and the XMM data provide at least factor of $\\sim 3$ better spectral resolution in the Fe K band than any previously measured flaring X-ray state. We find that there is a broad feature in the \\sim 5-7 keV band which could be interpreted as a relativistic Fe K$\\alpha$ emission line.
