12th Aug 2019: Data download temporaily put on hold

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!
