(fwd) RXJ1450.5+6403 spectroscopic period ... (Thorstensen)

Dear Colleagues,

    More on this new SU UMa star:  In April of this year I 
obtained radial velocities which showed the orbital period to be
short.  The period determination was not conclusive but the 
leading candidates are 0.0588 and 0.0599 d, both of which are
a little shorter than Tonny Vanmunster's preliminary superhump
period of 0.0617 d.  The spectrum at minimum light appeared
typical of SU UMa-type dwarf novae.  I have more observing time
next month (after which it will presumably have faded back to
minimum), and I should be able to resolve the period ambiguities
then.

                                        John Thorstensen
