We present new 6 cm observations of the binary radio, X-ray and ɿ -ray star GT0236+610 (LSI+61°303) obtained in August 1984 and September 1986. Ve calculate an improved period for the source's periodic radio outbursts of 26.50 ± 0.03 days. No significant period derivative was found. Based on an analysis of 201 flux density measurements from 1977 August to 1986 September, we find evidence for a possible 4 year modulation of the amplitude of the 26.50 day periodic radio outbursts. A precessing jet model for this long period modulation is discussed. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
