Popis:	Measurements of the excited hydrogen radio line H56a have been carried out in Orion A, W3, W12, W51 and DR 21. The electron temperatures obtained are lower than those deduced from the non-LTE analysis of observations at longer wavelengths. For the Orion nebula, detailed consideration gives Te = 7000 – 7300 K.
