This star sounds like a wonderful new discovery - let's fire away at it!
2000 coords 19 53 05.0 +21 14 50
Go for it - a good project until the star sinks down into sky noise.

Subject: (cba:news) V405 Vul - superhumps have (fully) grown
A first inspection of the light curve, resulting from my CCD photometry time series session of V405 Vul on Aug 29/30, 2000, clearly shows that superhumps have now strongly grown in this system. We measure a full superhump amplitude of about 0.4 magnitudes. Data were obtained using the 0.35-m f/6.3 telescope + unfiltered ST-7 CCD at CBA Belgium Observatory.
Please remark the object is still bright tonight (Aug 30/31).
We'll disseminate additional information about the present V405 Vul outburst, once we have gone through the analysis of the CCD data that we also received from other observatories.
