Dear CBAers,

We've been waiting for this one to go off!  One of the various "Boo" 
entries in the Downes catalogue... and with no known outburst.  With 
deep eclipses, the light curve is bound to be EXTREMELY interesting!

In the south, V442 Oph and V4743 Sgr continue to be of great interest. 
Both are flashing periodic signals - not seen before, at least not 
photometrically (V442 is flashing its radial-velocity period).  We could 
definitely use more coverage.

I think it's time to call off the dogs on V1084 Her = RX1643+34... and 
sic 'em on DQ Her.  Especially if you can get pretty fast integrations.

More tomorrow.

joe

And there's this one too!  Not eclipsing, but of substantial interest 
due to the (like) rarity of outburst.  A good post-midnight object after 
1502+33 sets.

3.4hrs of unfiltered photometry of IL Vul tonight shows what appear to 
be 0.1
mag superhumps with period ~0.075d on top of a slowly fading trend. The 
mean
magnitude of IL Vul during the run was 16.1.

It therefore looks likely that IL Vul is a UGSU-type dwarf nova.

Dear CBAers,

Thanks for all the great data on SDSS1502 = Boo!  Very well-defined 
eruption, lots of eclipses and superhumps and features well suited for 
timing studies.  It's down to around 16 now, so I imagine will soon 
disappear from most of your radar screens.  But if you're up to a 
deep-sky challenge, stay with it.

Just to reiterate, V442 Oph is in a very rare low state (around 17) and 
we'd like to hammer away on it for a while longer.  Still pretty sparse 
CBA coverage (nearly all from Bob Rea)... though enough to define the 
orbital period.  A good star to gang up on.

Time to quit on RX1643+34 = V1084 Her.  We've got enough.

Many DQ Her stars (intermediate polars) in the sky now.  We track the 
pulse timings of these stars, and now's the time for the early-season 
timings that are vital.  DQ Her, V2306 Cyg, and V455 And are all good 
northern targets now.  V1223 Sgr, RX1730-05 (Oph), AO Psc, and FO Aqr 
are all good southern or equatorial targets.

We'd like to go another 1-2 weeks on V4743 Sgr.  What a strange star - 
full of periods, but still quite mysterious as to what they mean!

1.9hrs of unfiltered photometry of this blue (g=20.10, r=20.06) object 
in the
SDSS catalogue showed apparent superhumps with period about 0.063d and 
amplitude
0.04 mag. Mean magnitude was 14.09C.

This appears to be a previously unknown SU UMa type dwarf nova in a 6 mag
superoutburst.

Dear Colleagues,

after one hour of time-resolved photometry on this star, I
can see it is humping with a full amplitude of about 0.1
mag.

So, my observations suggest this is a new SU UMa star.

Best,
Gianluca
