[vsnet-alert 386] rare outburst of SW UMa

[Taichi Kato <tkato@kusastro.kyoto-u.ac.jp>]

  SW UMa is undergoing one of its rare outbursts as indicated by the following
observations by L. T. Jensen (vsnet-obs 2562 message).

SW UMA     960411.847 14.0
SW UMA     960411.875 13.5
SW UMA     960411.955 11.7
SW UMA     960411.969 11.4, rapid rise to maximum

  The outburst is apparently on its way to maximum.  High-speed photometry
is therefore highly encouraged, by taking the present first-ever opportunity
to cover an entire (super)outburst of this unique dwarf nova.  A systematic
search for super-QPOs (QPOs with gingantic amplitudes, which probably appear
only during the early stage of superoutbursts; cf. Kato et al. 1992 for this
particular object: PASJ 44, L215) may be interesting.

  SW UMa was last seen in outburst in Aug. 1993.  We will keep readers informed
via VSNET mailing lists and the VSNET Home Page.
