AAVSO Bulletin 73 for 2010 - Stars in Need of Observations

                        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.
