10. K2’s timeline 2014: Campaigns 0-3 2015: Campaigns 4-7 2016: Campaigns 8-12 2017: Campaigns 13-16 Campaigns 17+ are at risk of fuel running out,
 their status is to be confirmed over the next year.
11. Campaign 9 (Apr-Jun 2016) - Towards Galactic Bulge. - Focused on a 3.7 deg2 microlensing aperture. - Other notable targets included: - Lagoon Nebula - >20 O-type stars - Quaoar - Calibrated data to hit the archive next week. - Microlensing science team is preparing detrended difference imaging maps for public release.
13. Campaign 10 (Jul-Sep 2016) - Virgo; high galactic latitude (+60°). - 28,000 targets, including 3C-273. - Module 4 retired mid-way.
14. Campaign 11 (Sep-Dec 2016) - Ophiuchus; low galactic latitude (+5°). - 14,000 targets, including M9, M19, NGC 6293, NGC 6355, Terzan 5 (globular clusters);
 also Titan, Enceladus, Trojan asteroids. Campaign 12 (Dec-Mar 2017) - Aquarius / Pisces; high galactic latitude (-60°). - Targets include TRAPPIST-1 and comet Chiron.

21. K2 Supernova Cosmology Experiment
23. The K2 Supernova Cosmology Experiment aims to monitor >10,000 low-z galaxies to capture >20 Type Ia Supernovae. Science goals include: -probing the circumstellar environments of the progenitors; -getting a detailed view of lightcurve variations; -improving the use of supernovae as standard candles. 
 Also: -improving constraints on supernova frequencies; -searching for optical counterparts of fast radio bursts. A workshop will be held at Ames in Feb or Mar (TBC) to organize the simultaneous ground-based observing efforts.
24. NEW: PRF Data Release - During commissioning, Kepler collected data in a 121-point dither pattern to sample its Pixel Response Function (PRF). - The PRF model was published by Bryson et al. (2010). - The underlying 15-minute cadence pixel data is now being processed for its first public release.
25. NEW: K2 Campaigns 0-1-2 re-processing - The first three K2 Campaigns were originally processed using a preliminary version of the pipeline. - These are now being re-processed: - adds lightcurves (long cadence); - adds collateral data products; - improves calibration in short cadence.
26. NEW: Kepler/K2 Visiting Scientist Program -The GO office is setting up a “Visiting Scientist” program to enable users to spend several weeks or months embedded in the Kepler/K2 office. -Ideally suited for users wishing to understand Kepler data in depth.
27. NEW: Kepler and K2 have new Project Scientists! Jessie Dotson (K2) Natalie Batalha (Kepler)
