Re: EX Hya outburst

   Please bear in mind EX Hya is an eclipsing system.  Any observation
(even visual) covering any eclipse during any outburst is extremely
important.  The required time resolution should be shorter than 1 min
(visual), or preferrably seconds.  The progress of the phenomenon (eclipse)
is expected to be very rapid, depending on the presence of a bright accretion
disk.

   Eclipse ephemeris (times are UT, geocentric):
