In order to have access to the Kepler Asteroseismic data you have to be a member of KASC. Please see the "New KASC member" page on how to become a member.


21st Feb 2020: Scheduled maintanence on Wednesday, 26th February

On Wednesday 26th February 2020 between 9:00-17:00 CET there will be scheduled maintenance of the computer systems at Aarhus University. This means that data downloads from the KASOC website will be unavailable during most of this timespan. We apologize for the inconvenience.

27th Jan 2020: Scheduled maintenance on Wednesday, 29th January

On Wednesday 29th January 2020 you may experience some downtime of the KASOC website.
This is due to scheduled maintenance of the Aarhus Astronomy Data Centre (AADC) servers, which hosts KASOC.
After the update, we will be back with an even faster and more secure website.
UPDATE (31/1): The maintenance ran smoothly with minor interruptions to the website, and we are now running on a new and improved system.

16th Dec 2019: File server crash

Shortly before lunch-time today we had a major crash of our primary file-server, which holds all the Kepler/K2/KASC data. No data has been lost, but it does mean that it is currently not possible to download data from the KASOC Data Search, Bundles, or Publications.
We will keep the KASOC website running, and other features like Star Catalog should not be affected.
We apologize for any inconvenience this may cause, and hope to have the systems back online as soon as possible.
UPDATE (20/12): Everything is now back to normal, and all data is available again.

30th Jan 2020: K2 Campaigns 8 and 10 reprocessed

Almost two years ago we announced that we were undertaking an effort to reprocess campaigns 0–14 using the same version of the Kepler/K2 pipeline used for C15 and subsequent campaigns. This version introduced several new features and improvements, such as more sophisticated pixel calibration, better identification of spacecraft …
