Suggestions for CV stars in the Southern Hemisphere

I have been looking for suitable CV targets observable from Chile. I have an interest in variables of the ER UMa and UGSS type.  Other than V1159 Ori and UU Aql, I'm finding it a bit difficult.

Any suggestions would be appreciated.

Stewart, you can interrogate

Stewart, you can interrogate the VSX database 

You can ask it to return UGSS, or UGER, or whatever you fancy. You can select to get the results returNed sorted by Dec, which will help you to find southerly targets

Settled on UU Aql

Jeremy,

Thx for your help. I've found UU Aql as a suitable target. Its listed as UGSS type in VSX although the data are a little sparse.

Southerly CV stars

Let me take a look at the ones I've observed from La Palma. Not sure whether by "southern hemisphere" you mean negative declination or so far south they can not readily be observed from the UK. Some equatorial stars are visible from both Chile and the UK.

...  Checking ... OK:

Not observed any ER or UGSS very far south, sorry.

HL CMa is a UGZ/IW so might be ok but not ideal for you. Very nice bright guide star near by, as is a white dwarf worth observing. The declination is -17 degrees.

BW Scl --- a UGZZ+GZ/GWLIB Declination is -39 degrees.

There are doubtless thousands if not hundreds more. The previous advice to consult VSX is strongly recommended.  Those two are just a couple I've observed.

How do you propose to observe them? Both Magellanic Clouds are full of variables of all kinds, so if you fancy more of a challenge ...
