1 2009arXiv0910.0954S White dwarf spin period = 33.0767 seconds.
2 GCVS Team Unusual flare X-ray system with pulsar. Becomes bluer in Max. In Min B - V = +0.92. Shows rapid irregular variations, which differ it from UV stars and UG system, though the spectra are somewhat similar. Simultaneous photoelectric and spectroscopic observations [AJ 70, 613, 1965.] show the existence of two types of flares: 1) intensification of emission lines accompanied by brightening in U and B; 2) intensification of continuum leading to brightening in U, B and V ("white flare"). Detailed spectroscopic investigation [J.A.Crawford, R.R.Kraft, ApJ 123, 44, 1956.]. Porb = 0.41165794d + 1.12*10**(-10)*E, The epoch T0 = JD2439030.621 [A.N.Feldt, G.Chincarini, PASP 92, 528, 1980.]. In the X-ray band (0.1 - 4.0 keV) pulsations with P = 33.0767s are observed [J.Patterson, D.Branch, G.Chincarini, E.L.Robinson, ApJ 240, L 133, 1980.]. In the optical range pulsations with P0 = 33.076737s as well as with P1 = 16.5s were noted [F.Jablonski, IBVS N1911, 1981., J.Patterson, ApJ 234, 978, 1979.].
