Last night (2014 Aug. 06.10903) I detected CSS 130418:174033+414756 (aka ASASSN-13ae), classified as type UGWZ in VSX, in outburst at magnitude 13.8 (visual). I would appreciate confirming observations from other observers!
Perhaps this object is misclassified? A previous outburst occurred just 15 months ago:

With a quiescence of around 20 this looks like a certain UGWZ. Maybe it's a very active one! This would be the one with the shortest outburst interval! Or maybe it's a extreme UGSU?
Hope to catch it with the BRT.

Eddy
I don't see too much evidence for type UGWZ in this system. Where has this come from? Kato?
Will check it out tonight if it's clear!

One hour ago I took some CCD V images of ASASSN-13ae. It's bright. My measurement (already in AAVSO Database) = 13.9755V.

Thanks for the heads-up! Definitely see it on my CCD images taken near 0830UT on 07Aug14.

Thank you, Juan-Luis and James, for your confirming observations.
I was able to see the star again last night, but it was near my limit, and I will probably not be able to see it again due to the bright moonlight.

Unfortunately, my ST-10XME is in for repairs so I had to use the "pretty picture" antiblooming CCD (SBIG STL-11K) with old Schuler 48mm photometric glass filters. Hope these ensemble, un-transformed BVR magnitudes are close to what other folks have gotten.
