Scientific paper

Continuum radio emission and hydrogen recombination-line emission were measured at 2.37 GHz with the 64-m antenna at Goldstone, California. The radio emission has the same general distribution as the optical nebula. The radial velocity of the nebula agrees with that of the adjacent dust cloud L 1630. The electron temperature is estimated to be approximately 7000 K. The excitation of the nebula is compared with current estimates of the ionizing flux from the exciting star, sigma Orionis.
