The K2 data from C5 is on its way to KASOC. Short-cadence data is available now (204 targets), but long-cadence data will take a few days to be available.
It has been discovered that there is a problem of highly elevated noise-levels in the newest release of data from the Kepler mission (data release 24) which seems to affect all short cadence data. Long cadence data does not seem to be affected and it is only the latest data release (24) that is affected.
Our recommendation would be, for now, to have a look at the earlier data releases instead, which you can also obtain from the KASOC website.
The Kepler team has been alerted to the problem and are looking into it.
Due to some system maintenance at Aarhus University, parts of the KASOC database is currently offline. This means that some of the data-files are currently not available. We are working on fixing these issues and have everything back online asap.
