#### 20th Aug 2019: TASC5/KASC12 materials available

All the material from this summers TASC5/KASC12 conference in Boston have now been made available:
http://kasoc.phys.au.dk/info_conference_kasc12.php

Due to malicious activity on our networks, the download of data from KASOC is currently been disabled. We are working hard on restoring the functionality and apologize for any inconvenience!
UPDATE (13/8): Everything is now back to normal, and data download is working.

#### 31st Oct 2018: Goodbye Kepler

Goodbye Kepler. You will be missed!
We can all take solace in the fact that the amazing data you have provided us will keep up busy, making new discoveries, for years to come.
Now, take a well-deserved rest - you have earned it!

#### 6th Sep 2019: Corrected C2 short-cadence TPFs released

Previously we announced that some recently reprocessed short-cadence target pixel files from C2R, C3R, and C5R were incorrectly calibrated. We estimated that of the 474 short-cadence targets in those campaigns, 175 were possibly affected at any level, and ~25% of those 175 were affected at a non-negligible level.

At the …

#### 15th Aug 2019: Final release of K2 high-cadence guide star photometry

About two years ago we announced the release of Kepler and K2 C0–C12 Fine Guidance Sensor (FGS) data. These data provide photometry and centroid positions for the guide stars that were used to main stable spacecraft pointing. These data contain the highest time sampling possible with Kepler, with integration …

#### 12th Aug 2019: Updated version of the K2 Handbook now available

An updated version of the K2 Handbook has been released and is available in PDF format via the K2 Documents page at MAST.

The updated K2 Handbook describes:

• Operation of the Kepler spacecraft for the K2 Mission — now updated through end-of-flight.
• How K2 targets were selected and apertures chosen — now …
