Brand new D, Dr, E, and ER-scale charts for QZ Ser are now available. Sequence is by M. Simonsen from USNO A2. Updated charts will be issued when beter photometry becomes available. http://vsnet.aavso.org/charts/SER/QZ_SER/ Also, I'd like to mention the Online AAVSO Chart Search Engine. It is a great tool for planning observations and quickly finding charts, such as HT CAS, for which the AAVSO has b-f scale charts including .01 mags and color data for good CCD runs. http://charts.aavso.org/searchcharts.shtml Aaron (PAH)
