  Compared to their centimeter-wavelength counterparts, millimeter
recombination lines (RLs) are intrinsically brighter and are free of pressure
broadening. We report observations of RLs (H30alpha at 231.9 GHz, H53alpha at
42.9 GHz) and the millimeter and centimeter continuum toward the
Becklin-Neugebauer (BN) object in Orion, obtained from the Atacama Large
Millimeter/submillimeter Array (ALMA) Science Verification archive and the Very
Large Array (VLA). The RL emission appears to be arising from the
slowly-moving, dense (Ne=8.4x10^6 cm^-3) base of the ionized envelope around
BN. This ionized gas has a relatively low electron temperature (Te<4900 K) and
small (<<10 km s^-1) bulk motions. Comparing our continuum measurements with
previous (non)detections, it is possible that BN has large flux variations in
the millimeter. However, dedicated observations with a uniform setup are needed
to confirm this. From the H30alpha line, the central line-of-sight LSR velocity
of BN is 26.3 km s^-1.
