12th Jul 2016: K2 campaign 8 data available

The K2 campaign 8 data is now available. We hope you have time to look at it even though most of KASC is at the KASC9 workshop in the Azores.

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.

5th Jul 2016: K2 Mission Recruiting Members for the K2 Users' Panel

The K2 mission is developing a K2 Users' Panel (K2UP), whose role will be to represent the voice of the community in regards to mission science, management policies, and products from the project. Specifically, the panel will be expected to:

  • provide input on data products and documentation from the mission
  • review the mission's science balance for the remaining observing campaigns
  • define what products are needed to preserve the legacy of the mission
  • recommend new services and identify current services that are superfluous

The panel will report to the K2 Project Scientist and K2 Program Scientists a few times a year via telecon and/or in-person meetings held at NASA Ames Research Center or major conferences like the AAS winter meeting. We anticipate members will serve on the K2UP for a term of at least one year.

Our goal is to form a panel consisting of 5-10 members that will have a first meeting via telecon in September 2016. To ensure that the K2 community is adequately represented, we anticipate selecting members with expertise that covers suitable fields of astrophysics and planetary science. If you are interested in participating in the K2UP, please send an email to keplergo@mail.arc.nasa.gov that contains a short description of your expertise and reasons why you wish to join. We will consider applications until 2 August 2016.

4th Jul 2016: K2 Campaign 8 data available

Long cadence light curves, target pixel files, and full frame images for K2 Campaign 8 are now available for download from the K2 data archive at MAST. The data are not yet searchable using the K2 data search interface, which will be available later this week.

The Campaign 8 target list included 24,187 standard long cadence and 54 short cadence targets, including 2,800 galaxies.

In addition, the campaign included several custom masks:

  • The planet Uranus was observed for roughly a month in short cadence, and the remaining time in long cadence.
  • Four irregular Uranian satellites were observed in long cadence over a period of one month (Caliban, Sycorax, Prospero, Setebos).
  • Six Hilda asteroids were observed in long cadence (1999 TJ90, 1999TS40, 1999 VG135, 2000 WC140, 2006 UB219, 2007 RY194).
  • Four Trans-Neptunian Objects (TNOs) were observed in long cadence (1998 SN165, 2001 QT322, 2003 QW90, 2005 RS43).
  • The irregular dwarf galaxy IC 1613 was covered using a 120-by-160 pixel mask.
  • Finally, we covered several very bright stars using custom pixel masks that collect the wings of the PSF.

Detailed data release notes are available on this website. We strongly encourage users to read these carefully.

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.
