BX Mon outburst

 According to T. Iijima, a symbiotic object BX Mon is
brightening. Weakneing of emission and strong blue continuum are
observed by his observation, thus an outburst of this object is 
implied.
 This object seems to have started an outburst in spring of 2008
according to VSNET + ASAS data. Multicolor observations by 
S. Kiyota also confirm Iijima's information since this object is
getting to blue between fall of 2008 and fall of 2009 as followings;


  20081119.569  8.29Ic  (Seiichiro Kiyota)

  20081119.571  10.38V  (Seiichiro Kiyota) (V-I = 2.09)

 This object underwent outbursts in 1999 and 2002.
Both outbursts have brightening of several months and 
decline of 1 ~ 2 years. Therefore brightening of this outburst is
relatively slow. Please pay attention to the behavior of this
object.
