STARS IN NEED OF OBSERVATIONS in AAVSO BULLETIN 73: Predicted Maxima and Minima of Long Period Variables for 2010 The stars listed below need additional observations. Please be aware that many of these stars are difficult to observe, and should be observed only by experienced observers. Please note that the symbol % after a star name indicates the star has fair to excellent CCDV or multicolor photometry but still needs visual observations. Because all of the Bulletin stars have decades of visual observations that predate CCD photometry, wherever there is photometry visual observations are also needed to allow correlation between the two types of data; continuity of visual observations is critical. AAVSO charts for these stars may be created and downloaded using the Variable Star Plotter (VSP) on the AAVSO web site or ordered from AAVSO Headquarters. Please check the web site or with Headquarters to make sure you have the latest sequence for a star. Please note that if a star listed here does not have a sequence in VSP, you should use the chart for that star from the Royal Astronomical Society of New Zealand, Variable Star Section; you may order the chart from the RASNZ or the AAVSO.
