Abstract: We present estimates of brightness temperature for 5 galactic masers in star-forming regions detected at space baselines. Very compact features with angular sizes of ∼23−60 µas were detected in these regions with corresponding linear sizes of ∼4−10 million km. Brightness temperatures range from 10 14 up to 10 16 K.
