Palomar 2 / C0443+313
(Updated June 2011)

RA: 04:46:05.91  DEC: +31:22:53.4 (J2000)

No known variables.

Supplementary Notes 

A variable search of Pal 2 was carried out by Rosino & Pinto (1973).
They concluded that the cluster does not contain any red variables, 
but the possibility that any RR Lyrae may be present could not be 
ruled out.

A CM diagram was published by Harris et al. (1997).  They found a 
well populated red horizontal branch with a sparser extension to the 
blue. Based on this, they concluded that it is likely that Pal 2 
contains RR Lyrae variables, but their observational data were not 
suitable for performing a search.

A VI color-magnitude diagram published by Sarajedini et al. (2007)
confirms that the HB is bimodal in color and that the cluster is 
located in a direction of high foreground absorption and differential 
reddening.
