Abstract
Quasi simultaneous H-alpha and radio observations of LSI + 61 degrees 303 during August-September 1993 are presented. The radio data show th at during the studied epoch the outburst has peaked at radio phase sim ilar to 0.6, at a level greater than or equal to 100 mJy. No significa nt variations in the H-alpha profile at phases 0.5 to 0.65 have been d etected. A remarkable increase of the EW and FWHM of the H-alpha blue peak is observed at radio phase similar to 0.23. Possible reasons are considered.
