Announcement of Earlier Kepler Data Release—from June 2011 to 1 February 2011
American Astronomical Society Electronic Announcement #214 – November 2010

Date Emailed: 10 November 2010


The Kepler project wishes to inform the community that it is moving
the next data release date (originally planned for June 2011) forward
to 1 February 2011. This data set (Quarter 2) is the first consisting
of a complete 3 months of observations. It will contain light curves
for approximately 165,000 stars (most of which are late-type Main
Sequence stars) brighter than 16th magnitude in the Cygnus & Lyra
constellations sampled at a 30-minute cadence. Three subsets of
one-month each of [up to 512] stars were sampled at 1 min cadence. The shorter
cadence data will be released on the same schedule.

The new release will augment the Quarter 0 & Quarter 1 data that were
released mid-2010. Q0 data is a unique set of ~10 days of data taken
during commissioning of ~53,000 stars of all spectral types with
kepmag<13.9. Q1 data consisted of 33 days of data of ~150,000 stars
taken between the end of commissioning and the first quarterly roll.
The motivation for the early data release is to better support the
2011 NASA Astrophysics Data Analysis Program (ADAP), a funding
opportunity which supports the analysis and interpretation of data in
the public archives. By tripling the volume of Kepler data in the
public archive, we hope to open the floodgates to research
opportunities that might be captured under the ADAP umbrella.

The project will hold a splinter session at the AAS meeting in Seattle
to inform potential users of how to make use of the archive.
