A series of H-alpha profiles (in total 1006 spectra in the H-alpha region) with the time resolution around 45 s were obtained on six nights between January 29 and February 7, 1988, to search for rapid spectral variability in the Be stars - Alpha Col, Rho Car and Eta Cen. No rapid variations of Fc and W(alpha) in Alpha Col and Rho Car, but such variations of Fc were present in Eta Cen on the night of February 2 and absent on other nights. Also, it was found that Fc and L(6563) of Eta Cen slowly increased from January 29, 1988 and reached to a maximum on February 2, 1988 with a subsequent gradual decay, without affecting the equivalent width of H-alpha.
