   The same flares (including the biggest one) are recorded in Torii-san's
almost simlutaneous observation.  The reality of such flares is now
perfectly established!  After combining several runs, there seems to be
quasi-periodic activity phases (analogous to GRS 1915+105, as inferred from
Santallo's initial observation), some of which evolved into giant flashes!

   Please make as intensive observations as possible!!
