9th Oct 2016: K2 campaign 9 data available

Data from campaign 9 of K2 has been made available on KASOC. Please note that this campaign is a little different, in the sense that the campaign was largely dedicated to the study of microlensing towards the galactic bulge.

Among other things, this means that there are no light-curves produced by the K2 Science Office.

Please have a careful read of the Data Release Notes.

16th Sep 2016: Scheduled downtime

KASOC will be unavailable on Tuesday 20th September 2016, from 9:00 CET until the morning of Wednesday 21st September 2016. This is due to scheduled maintenance of our server-rooms. We hope this will not cause too much inconvenience.

1st Sep 2016: Final processing of short cadence is available

The final processing of short cadence data from the nominal Kepler-mission (Data Release 25) is now available for download under "Data Search".
In this release the previously reported problems with the short cadence data has been solved.
Bundles with these files are being created, and will be available shortly under "Bundles".

9th Dec 2016: K2 Campaign 10 data processing complete

Pipeline processing for K2 Campaign 10 is now complete and the data are in the process of being shipped to the data archive at MAST. We anticipate that the data will become available for download on or before December 22nd.

Alongside 28,345 standard long cadence and 138 short cadence targets, the Campaign 10 science program included a large number of galaxies owing to the field's location near the north galactic pole. The extragalactic targets include the well-known quasar 3C 273.

Keep an eye on this website for an announcement of the release and the associated data release notes.

6th Dec 2016: Reprocessed data for K2 Campaign 1 now available

The original data release for K2 Campaign 1 in 2014 used a prior version of the pipeline (v9.2) which only produced "Type-1" FITS Target Pixel Files. The Campaign has now been re-processed using the mature version of the pipeline (v9.3) which updates the pixel files to "Type-2" TPFs (differences detailed here). The new release also adds long-cadence lightcurves, cotrending basis vectors, and collateral products such as smear data.

The re-processing also corrects a short cadence calibration bug. Short cadence targets with significantly improved calibration are identifed in the list of affected targets at the MAST.

Finally, the C1 data release notes have been updated to include more details on the data characteristics, and to explain issues associated with the first few days of data which were taken before a pointing tweak.

The reprocessed Campaign 1 data are now available from the K2 data archive at MAST. Campaigns 0 and 2 are currently undergoing a similar reprocessing effort which is expected to be completed in early 2017, at which point all Campaigns will have been processed using the same version of the pipeline.

5th Dec 2016: K2 & TESS Splinter Session at #AAS229 on 4 Jan 2017

The TESS and K2 Missions are convening a joint special session at the 229th meeting of the American Astronomical Society (AAS) being held in Grapevine, Texas, this January.

The session will take place on Wednesday evening, January 4th, 2017, at 7:30 pm in room "Texas C" at the Gaylord Texan Convention Center. All AAS participants are invited to join the gathering to learn more about present and future science opportunities with K2 and TESS.

The schedule is as follows:

  • 7:30pm: K2 Mission Update – Jessie Dotson, NASA Ames
  • 7:40pm: K2 Campaigns 16 & 17 Supernova Cosmology Experiment – Armin Rest, STScI
  • 7:50pm: K2 Campaign 9 Microlensing Experiment – Calen Henderson, JPL/Caltech
  • 8:00pm: TESS Mission Update & Overview – George Ricker, MIT
  • 8:10pm: TESS Science Preview – Jennifer Burt, MIT
  • 8:20pm: TESS GI Program – Padi Boyd, NASA Goddard
  • 8:30pm: K2, TESS, and The Future – Jessie Christiansen, Caltech
  • 8:40pm: Q&A and Socializing (bar in room open until 9pm)

In addition to the special session, a wealth of Kepler/K2/TESS-related talks and posters will be presented throughout the meeting, and the missions will also operate a booth in the exhibit hall.

(PS: Come early if you like warm pretzels!)
