We have released a new GUI search interface to the light curve database. The new interface has sliders for specifying ranges, and checkboxes for specifying the surveys, telescopes, and variable star types you are interested in. It supports both a range search and a cone search.

The search results are displayed both in an interactive table, and in a Google Sky viewer. You can click on any result in the Google Sky viewer to quicky see thumbnails of the light curves.

Additionally, some searches now execute much more rapidly, and we have added ASAS light curves.

Many more new features are coming soon, including an interactive light curve viewer, more data, and searching on additional parameters, such as star brightness and time ranges.

Please visit us often to keep up to date with all the improvements!

A postdoctoral position is available for an outstanding individual capable of taking a leading role in research on the analysis of scientific time series. The position is co-funded by the IIC Time Series Center at Harvard and by a recent NSF grant supporting Interdisciplinary Machine Learning Research and Education. more »

The first official release is its way. It has been delayed to June 21st from June 4th while we do internal testing to get rid of some pesky bugs. That will include data from MACHO, TAOS, ESSENCE, OGLE (variables only). A full suite of web services will be available along with documentation and examples. Also a new search interface will be available that allows all sort of queries. Check it out !
