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
