[vsnet-alert 746] Re-brightening of T Leo

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

   Observations to vsnet-obs indicate the dwarf nova T Leo is showing
a remarkable re-brightening, a presumable superoutburst triggered by the
'precursor' outburst on Feb. 19.  Selected observations since the decline
of the first maximum:

   YYMMDD(UT)   mag    code
   970220.378   111    MRV
   970220.447   111    MRV
   970220.485   109    HSG
   970220.624   107    Wnt
   970220.717  11.25V  Kis
   970220.828  11.36V  Kis
   970221.198   118    MRV
   970221.485   118    HSG
   970221.708  <119    Wnt
   970222.239  <129    HSG
   970222.581  11.73V  Kis
   970222.635  <116    Wnt
   970222.678   109    Ioh
   970222.717  11.09V  Kis
   970223.180   108    MRV
   970223.241   107    MRV

   V-band CCD observations by S. Kiyota (vsnet-obs 5127) indicate superhumps
probably already appeared during the decline phase of the precursor outburst.
The present behavior strong resembles that observed during the initial stage
of the 1993 Jan. superoutburst (T. Kato, in preparation).
