New AM CVn star, reasonably bright - definitely a very tempting target 
right now!!

ASASSN-15kf: superoutburst of a new AM CVn-type

    Berto Monard has reported observations.
The data show superhumps with a period of 0.01922(9) d
and an amplitude of 0.12 mag.  The period strongly
suggests an AM CVn-type object (similar to CP Eri?).
According to ASAS-SN data, outbursts appear to be
relatively rare.  Since the object is relatively bright,
intensive observations of the start of the next outburst
will provide us an opportunity to detect stage A
superhumps.  Monitoring for outbursts by visual observations
are also very helpful.

Basic data:

ASASSN-15kf 	--- 	------- 	15:38:38.24 	-30:35:49.7 	2015-05-27.12 
14.93 	SDSS 	DSS 	VIZIER 	------- 	CV candidate, matches to B=19.4 
source, previous outbursts in CRTS data, V>17.0 on 2015-05-24.05, V=15.0 
on 2015-05-27.1

ASASSN-15kf 20150524.05 <170V ASN
ASASSN-15kf 20150527.10 150V ASN
