15th Jun 2020: Reprocessed TESS data for sectors 1-19

As you may have read in the news from the TESS Science Support Center, the TESS data from sectors 1-19 are going to be reprocessed and updated in the coming months. This will mean that as data is re-released, they will no longer be available on the MAST archive.
But fear not! On the TASOC archive, we will make sure that all previous versions of data will always be available, so you can always reproduce your TESS results.

10th Jun 2020: Scheduled maintenance today, 13:00-16:00 CEST

We are doing some scheduled maintenance of our systems this afternoon, so data downloads will not be available for some time during that period.

29th May 2020: Did you miss an online event? Watch the recording!

We have now made it possible to watch recordings of online seminars and conferences (if they were recorded) under "Online Events".
