3rd Jan 2017: K2 campaign 10 data available

Data from campaign 10 of K2 has been made available on KASOC. The data release notes have not yet been made available, but we will provide it as soon as it is available.

Please note that there are a few unique features in the C10 data:

  • The first six days of data, dubbed C10.1, were collected with a pointing error of 3.3 pixels from the nominal field-of-view, so they were only processed through CAL to make "Type 1" target pixel files. Among other things, this means that there are no light-curves produced by the K2 Science Office.
  • The remainder of the campaign, dubbed C10.2, was processed through the entire photometry pipeline, creating "Type 2" target pixel files and long-cadence light curves.
  • Module 4 was lost part way through C10.2, which powered off the photometer and produced a 14-day data gap.

14th Dec 2016: Scheduled downtime

Tomorrow (15/12-2016) we will be doing some scheduled maintenance of our systems, so the KASOC website will be unavailable for a few hours. We apologize for the inconvenience.

13th Dec 2016: Reprocessed data for K2 C1

Reprocessed data for K2 Campaign 1 (Data Release 14) is now available for download.

This release corrects the short cadence pixel calibration bug previously described in the Global Erratum for Kepler Q0-Q17 & K2 C0-C5 Short-Cadence Data (KSCI-19080). The new release also includes lightcurves for all long cadence data, plus improvements to the target pixel files.

Please have a careful read of the Data Release Notes.

7th Jul 2017: Share your plan for K2 Campaign 16 ancillary observations

K2 Campaign 16 (Dec 7 - Feb 25) will be "forward-facing", making possible contemporaneous ground-based observations from Earth. Many teams have now secured telescope time to provide polychromatic photometry and spectroscopy of the field during the Campaign, e.g. for the benefit of the K2 Supernova Cosmology Experiment as well as …
