BZ UMA
According to the AAVSO News Flash No 21 issued yesterday, T.Burrows
of USA has detected an outburst of this UG star on May 14.21UT at
13.7v. Gary Poyner, Birmingham, UK estimated it at 10.7 on
May 14.92UT (0.40-m reflector). This star is on the Recurrent
Objects Programme of the UK Nova/Supernova Patrol.
According to the AAVSO database, a narrow outburst occurred on
1995 June 14 when the star reached mag 10.5.

Gary Poyner adds:

As you are all probably aware by now, AAVSO observer Tom Burrows
has detected an outburst of BZ UMa on May 14.2153 at mv=13.7. The
mag quickly increased to 11.9 by 14.3257.  My own observations last
night and this morning show it to have risen to mv=10.6. Superhumps
have yet to be observed in this star, despite current thinking that
it belongs to the UGSU subgroup. CCD observers have an excellent
opportunity to produce valuable results here, as well as visual
observers.  Please monitor as closely as possible and keep me
updated.
