3rd Jan 2017: K2 campaign 10 data available

Data from campaign 10 of K2 has been made available on KASOC. The data release notes have not yet been made available, but we will provide it as soon as it is available.

Please note that there are a few unique features in the C10 data:

  • The first six days of data, dubbed C10.1, were collected with a pointing error of 3.3 pixels from the nominal field-of-view, so they were only processed through CAL to make "Type 1" target pixel files. Among other things, this means that there are no light-curves produced by the K2 Science Office.
  • The remainder of the campaign, dubbed C10.2, was processed through the entire photometry pipeline, creating "Type 2" target pixel files and long-cadence light curves.
  • Module 4 was lost part way through C10.2, which powered off the photometer and produced a 14-day data gap.

14th Dec 2016: Scheduled downtime

Tomorrow (15/12-2016) we will be doing some scheduled maintenance of our systems, so the KASOC website will be unavailable for a few hours. We apologize for the inconvenience.

13th Dec 2016: Reprocessed data for K2 C1

Reprocessed data for K2 Campaign 1 (Data Release 14) is now available for download.

This release corrects the short cadence pixel calibration bug previously described in the Global Erratum for Kepler Q0-Q17 & K2 C0-C5 Short-Cadence Data (KSCI-19080). The new release also includes lightcurves for all long cadence data, plus improvements to the target pixel files.

Please have a careful read of the Data Release Notes.

21st Feb 2017: K2 Campaign 13 science program now available

The science program and target lists for K2 Campaign 13 have now been posted on the approved targets & programs page.

Campaign 13 is scheduled to run from March 8th through May 27th, 2017, and will be observing towards the constellation of Taurus in the Galactic Anti-Center direction.

The target list includes 21,434 standard long cadence and 109 standard short cadence targets. Notable targets include:

  • members of the Taurus star-forming region including two well-known T Tauri-type stars:
    • HL Tau (EPIC 210690913);
    • LkCa 15 (EPIC 247520207);
  • the nearby Hyades open cluster;
  • the distant clusters NGC 1647, NGC 1746 and NGC 1817;
  • 33 galaxies;
  • 6 Trojan asteroids;
  • 8 Trans-Neptunian Objects (TNOs);
  • 1 Comet (246P/NEAT).

Moreover, a total of 33 bright stars (Kp 0-6), including Aldebaran and more than 15 members of the Hyades, are being observed using a custom 40-pixel diameter circular aperture mask. Such circular masks capture the PSF cores while excluding the long saturation columns which tend to bleed off silicon. Nine bright Hyades members are also being observed in short cadence using a similar custom mask.

15th Feb 2017: Funding available for Kepler & K2 data analysis through ADAP

The Kepler/K2 community is being alerted to the open call for proposals to be submitted to the Astrophysics Data Analysis Program (ADAP), which provides financial support for US-based investigations whose primary purpose is the analysis of NASA space astrophysics data that are archived in the public domain at the time of proposal submission.

ADAP proposals are solicitated annually as part of NASA's Research Opportunities in Space and Earth Sciences (ROSES) solicitation. Typical ADAP funding amounts range between $40,000 per year to more than $200,000 per year, and can run for up to 3 years.

Proposals for the 2017 call are due on May 16, 2017. All Kepler/K2 data that will have been released to the community as of that date will be eligible for inclusion in ADAP proposals. This includes all Kepler prime mission data and K2 Campaigns 0 through 10.

Note: studies of Solar System bodies based on Kepler/K2 data are not eligible for funding under the ADAP, they may be submitted to the DDAP program instead.

2nd Feb 2017: K2 Campaigns 14, 15 and 16 Director's Discretionary Targets program

A small percentage of the available K2 pixels in each campaign may be allocated by the K2 Guest Observer (GO) Office Director as Director's Discretionary Targets (DDTs). The primary utilization of DDT programs is in support of community-proposed requests that are based on exceptional, time-critical observing opportunities that cannot be accommodated with the regular cycle of Calls for Proposals for K2.

We are currently accepting DDT proposals for Campaigns 14, 15 and 16. The proposals are due by 23:59 PT (Pacific Time) on the following dates:

  • February 23, 2017 for Campaign 14
  • May 25, 2017 for Campaign 15
  • September 7, 2017 for Campaign 16

For further information on the DDT program for K2 and the requirements for proposal submission, check out the DDT website. Proposals should be submitted via email to keplergo@mail.arc.nasa.gov.
