For those who observed/are observing LPH128:  in addition to the two 
other variables in the field mentioned in an earlier email, the star GSC 
3973-1124 about 13' ENE of LPH128 is variable.  The period appears to 
be  0.49d and the range is at least 0.25 mag.  If anyone included this 
star in their coverage I'd be interested in getting their photometry so 
I can nail down the period and get it entered into VSX.
