Variable Star Targets in OGLE

Over the last few years I have identified quite a few variable star targets that I have never followed up in detail. It would be a shame if these were to just sit on my computer forever without somebody else having the opportunity to have a look at them. So over the next few months I will post full details of these objects for people to play around with in any way they want.

Please appreciate that all these targets are offered in good faith but it is your responsibility to check if any of them have been independently discovered and published elsewhere.
