27th Apr 2016: Problems with download of older data releases

Due to computer system-work in Aarhus, some of the older versions of Kepler/K2 data is currently not available for download through KASOC. The newer data releases are not affected. We will try to keep you up-to-date when everything is back online again.

27th Apr 2016: K2 campaign 7 data available

The data from K2 campaign 7 is now available for download, both from the "Data Search" interface and in "Bundles" for the cluster Ruprecht 147, trojan asteroids and ex-planet Pluto. Enjoy!

7th Mar 2016: Long Cadence Data Release 25 is available

All of the long cadence data from Data Release 25 has now been made available through KASOC. Have a look at the documentation to see what the changes are, compared to the earlier DR24 release.

9th Jun 2016: K2 Mission Officially Extended Through End of Mission

Today NASA announced that the K2 mission is officially extended, based on a recommendation from NASA's Astrophysics Division's 2016 Senior Review of operating missions. The extension includes funding for three additional years plus a closeout period. K2 science operations will therefore be covered beyond when the on-board fuel is fully depleted, anticipated to be sometime in 2018.

Details about the recommendation can be found in the 2016 Senior Review report. In particular, the report noted that "...with a very efficient GO program, the project includes worldwide participation covering every continent except Antarctica. The GO program is recognized as a major reason for the wealth of new scientific results."

For an overview of the K2 mission's current status, check out the latest Mission Manager update.

2nd Jun 2016: K2 Campaign 10 science program now available

The K2 Campaign 10 science program has been posted online. The target list includes 28,345 standard long cadence and 138 short cadence targets.

Owing to the high galactic latitude of the field, the standard long cadence targets include 4,950 small galaxies. In addition, 27 larger galaxies are targeted using custom pixel masks. The short cadence list includes the well-known extragalactic object 3C 273, which is the optically brightest quasar in the sky.

In addition, large pixel masks will be obtained to cover 11 Hilda asteroids, 4 TNOs, and comet 67P/Churyumov–Gerasimenko which is currently being investigated by the Rosetta mission. Finally, K2 will also observe 8 very bright stars by targeting just the central region of pixels around these targets but excluding the bleed columns.
