[vsnet-alert 12427] EX Hya

[Hiroyuki Maehara]

  The MAXI transient alert reported an X-ray brightening of 
the intermediate polar EX Hya on Nov. 27.

 I carried out time-resolved photometry from Nov. 28.83 to 28.87.
The object was at almost normal brightness (~13.4mag) and faded 
by 0.4 mag during the observation.

Hirosawa-san also reported that the object was not in outburst.

EX Hya becomes bright, but it is difficult to estimate flux (but, more
