22nd Apr 2020: Data file access problems

Due to some network problems in Aarhus, the KASOC website is currently experiencing problems with accessing data files on our file-servers, so download of files is currently not possible.
We are working hard on fixing the issues, and apologize for the inconvenience!

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.

9th Apr 2020: K2 Campaigns 12 and 14 reprocessed

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 pointing …
