There's an ancient rule that says the most fascinating outbursts occur 
during scientific meetings, when astronomers aren't near their 
telescopes.  Holds true again.  Seemingly a great target, and very much 
wanting multi-longitude coverage, since the position is a tad off-season 
(2155+26).

Of interest partly because it's a first-ever-recorded outburst, partly 
because the range of brightness is so high (8 mag)... but mostly because 
it's so bright.  Dwarf novae (assuming that's what it is) are standard 
candles, so this dwarf nova would be quite nearby.  The nearest stars 
teach us an awful lot!  INcluding: how near they are.

Maybe of interest to observe for CBA members.
Too far north for Chile, tough.

ASAS-SN has four V-band detections of a very bright transient source

Name                  RA	Dec	            Discovery	V
---------------------------------------------------------------------------
ASASSN-14cl	 21:54:57.62	26:41:16	2014-06-14.52	10.66

Very bright CV candidate, V>16.0 on 2014-06-13.5, V=10.7 on 2014-06-14.52
(four detections in two cameras), matches to g=18.8 blue SDSS star

No previous outbursts in CRTS data, but some variability present.
