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".

25th Oct 2016: K2 Cycle 5 deadline fast approaching

The deadline for K2 Cycle 5 Step-1 proposals is just over a week away. This call is for targets falling into fields for Campaigns 14, 15 and 16. Proposal submission is a 2-step process and both steps are mandatory. Step-1 proposals are required to be submitted through the NSPIRES website by 23:59 EST November 3, 2016. Step-1 proposals are not scientifically reviewed and consist of a title, project summary and list of team members.

6th Oct 2016: K2 Supernova Experiment Workshop on Feb 14-16, 2017

We previously announced that in order to maximize the science return from the remaining fuel, the K2 Campaign 16 field has been changed to enable a forward-facing supernova survey. In addition to benefiting from low galactic extinction, the new field allows simultaneous observations to be made from the ground to complement K2’s single-bandpass photometry, i.e. allowing K2's supernovae to be characterized spectroscopically.

The survey is called the K2 Supernova Cosmology Experiment. Its aims include, but are not limited to:

  • monitoring >20,000 galaxies to gather a statistical sample of the best supernovae lightcurves ever obtained;
  • catching the critical first few hours of supernovae, allowing different explosion physics and progenitors to be elucidated;
  • improving the calibration of Type Ia supernovae for cosmology by determining the key parameters needed for distance fitting.

Proposals to select and analyze K2 targets for this Campaign are eligible for funding up to $150,000 as part of K2 GO Cycle 5 (which also accepts proposals from all other areas of astrophysics and planetary science). The Step 1 deadline is Nov 3, 2016.

To help the supernova community plan the observations and follow-up, the mission will be hosting a K2 Supernova Cosmology Workshop on Feb 14-16, 2017, at NASA Ames in Mountain View, California.

The motivations for this workshop include:

  • planning the K2 observations with Kepler/K2 team members;
  • coordinating the simultaneous, ground-based follow-up observations and proposals;
  • preparing the data analysis and interpretation efforts, e.g. informed by the previous supernovae observed by Kepler;
  • exploring synergies with other space missions, wavelength regions, and science areas.

This will be an unconference-style meeting with a limited number of introductory talks and a strong focus on participant-led breakout sessions. The final day will provide ample time for drafting papers and observing proposals.

Details on the venue, accommodation, and registration are available on the meeting webpage.

5th Oct 2016: K2 Users' Panel selected

The K2 mission has developed 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. More information on the panel's responsibilities and any reports generated can be found on the K2UP page.

The panel members are:

  • Padi Boyd (Chair), NASA Goddard Space Flight Center
  • Ben Montet (Deputy Chair), University of Chicago
  • Ian Crossfield, UC Santa Cruz
  • Saskia Hekker, Max Planck Institute for Solar System Research
  • JJ Hermes, University of North Carolina, Chapel Hill
