(cba:news) MAXI J1820 = ASASSN-18ey URGENT (Joe Patterson) [2018-03-31T09:57:11Z]

Hi CBAers,

Can you immediately send any data - just a snapshot magnitude would be 
great - you have gathered on this star in the last two days?  And if you 
don't have any, can you immediately get one.  Just one magnitude would 
be great!  The HST observation window is imminent, and the brightness is 
critical to pass the test for observation (a go/no-go).
