13th Nov 2015: Campaign 5 data release note

The campaign 5 data release note (data release 7) is now available:

12th Nov 2015: Campaign 5 data is now available

All K2 campaign 5 data is now available in KASOC under "Data Search" and bundles of the superstamps in this campaign are also available under "Bundles". This consists of the star cluster M67 and the trans-Neptunian object (126154) 2001 YH140. The data release note is not available from the science office, but as soon as it is, we will make it available as well.

5th Nov 2015: K2FOV tool updated to newest version

The newest version of the K2FOV tool now works up to and including campaign 13. The new version will, in addition to the normal output, also return anticipated CCD columns and rows for all targets.

7th Nov 2015: K2 Campaign 9 Microlensing Science Team Selected

K2 Campaign 9 will be executed in April 2016 and will be dedicated to a study of gravitational microlensing events. The Campaign 9 microlensing experiment involves the Kepler spacecraft observing in the +VV direction at fields toward the Galactic bulge. The aim of this program is to simultaneously observe gravitational microlensing events with K2 and from Earth in order to see a parallax effect in the shape and time of the lensing event.

The Microlensing Science Team (MST) was selected through a peer-review process during K2 GO Cycle 3 by a panel of experts. The aim of the MST is to both coordinate with and make recommendations to the K2 mission regarding the best observational methods to use during Campaign 9, allowing the highest value science return. Additionally, the MST will serve the interests of the community by, for example, facilitating simultaneous ground-based data collection, developing novel methods for crowded field photometry, and providing completeness and reliability studies of detected microlensing events.

The MST is comprised of the following people:

  • David Bennett (NASA Goddard Space Flight Center)
  • Andrew Gould (Ohio State University)
  • Calen Henderson (JPL/Caltech)
  • David Hogg (New York University)
  • Matthew Penny (Ohio State University)
  • Rachel Street (Las Cumbres Observatory Global Telescope Network)

The latest updates on the Campaign 9 microlensing experiment will be posted here.

Since Campaign 9 differs from previous and future K2 Campaigns (where targets are proposed by the community at large), the Guest Observer Office is offering a small number of pixels for approved Director's Discretionary Target (DDT) programs. The call for DDT proposals can be found here. The deadline for DDT proposals for Campaign 9 is December 10, 2015.

2nd Nov 2015: K2 Campaign 5 Data Release

Target pixel files, light curves, and full frame images for Campaign 5 are now available for download from the K2 data archive at MAST.

In Campaign 5, 25,850 long cadence and 204 short cadence targets were observed. We additionally collected large pixel masks over dwarf planet (126154) 2001 YH140. We also observed the open cluster M67. The cluster was tiled with 72 individual apertures to create a contiguous 400x400 pixel region over two channels.

Detailed data release notes for Campaign 5 are available.

1st Nov 2015: New Kepler/K2 Science Center Website Launched

The Kepler/K2 Science Center has launched a new website. The reorganized pages, which you are looking at right now, provide resources for scientists interested in using data from the missions.

New features of the website include:

  • an updated list of future K2 campaign fields;
  • instructions to apply for Director's Discretionary Time (DDT) during Campaigns 9 and 10;
  • preliminary instructions to apply for targets and funding related to Campaigns 11, 12 and 13;
  • information on the Campaign 9 microlensing experiment;
  • a comprehensive overview of the Kepler and K2 data products;
  • a new publication database including citation statistics.

The previous Science Center website has been preserved with a warning message at the top of the old pages.
