[vsnet-obs 344] outburst of TT Boo

TT Boo is on outburst now! I found it was on outburst at 20:00(UT) on March
24 when I do spectroscopic observations. The V magnitude was probably larger
than 13.0. My spetroscopic observation also showed deep absorption lines of
Hbeta, Hgarma and others. The observations from 16:40 to 21:00(UT) on March 
25 showed less deep absorption lines than those on March 24, but they are 
still deep. Besides TT Boo, I have done some spectroscopic observations on
AT Cnc, ER UMa, CY UMa, RZ LMi, TU Leo and AK Cnc from March 21 to 25.
