Under Observered Variables

I frequent the AAVSO and the Yahoo VSObs-Share web sites often, noting potential objects for observation.  Gary Poyner recently posted a visual observation for V532 OPH, a recently discovered RCB star.  I was amazed only to see 13 observations for V532 OPH in the AID over the last 365 days.  What are some other "under observed" variables?  Many can be found in the LPV Circular or Tom Bretl's AAVSO LPV Bulletin.exe program.  Here are some of my candidates for "under observed" variables:  RR VIR with 44 observations over the last 365 days with mostly CCD observations by SXN and PKV, T OPH with 34 observations over the last 365 days, U CAP with 29 observations over the last 365 days and X CAP with 15 observations over the last 365 days.  All of the above are now in my visual and CCD monitoring programs.  Many other variables of all types may be "under observed."  Most of the YSO's come to mind.  Many "legacy" LPV's are also under observed.  Does anyone else have specific variable stars that are "under observed" that require additional attention?  Kevin - PKV
