Z CMa in outburst

 By the way, this star is said to belong to FU Ori type.
However, a variation this star is not like FU Ori type.
This star shows risings whose amplitudes are around 1
mag at about one year intervals. Other FU Ori stars, for 
example FU Ori, V1057 Cyg, do not show such variations like
outbursts.
 Z CMa may be a little different from usual FU Ori type stars.
