Results are presented of a spectrophotometric investigation of the two brightest condensations in the galaxy NGC 2814 using data obtained by the 2.6 m telescope of the Crimean Astrophysical Observatory and the 6 m telescope of the Special Astrophysical Observatory. It is found that the conditions of ionization and excitation in the condensation of NGC 2814 are similar to those in normal H II regions. The electron densities and electron temperatures are found to be 380/cu cm and 10,000 K in the central condensation, and 260/cu cm and 7700 K in the northern condensation, respectively. The internal absorption in the central region is found to be of the order 1.87 m, while appreciable internal absorption is not observed in the northern condensation. The northern condensation is determined not to have a chemical composition appreciably different from galactic H II regions, whereas there is a certain deficit of heavy elements in the central region. These findings indicate that there are regions of star formation in NGC 2814.
