The current Sentinel Online website, which has been active for eight years as the main provider of scientific-technical information on the Copernicus Sentinel missions, is due to change—next week it will take on a whole new dimension.

Collision avoidance manoeuvres were executed on Copernicus Sentinel-1B to reduce the risk of collision with an object, potentially occurring at 08:33 UTC on 20 December 2020.

Due to an issue that occurred at PDGS level, the Near Real Time Copernicus Sentinel-3 OLC Level 1 and 2 products from approximately sensing time 06:30 to 08:30 UTC on 21 December 2020 could be delayed.

The infrastructure incident on the Data Hubs, which occurred at 05:00 UTC on 22 December 2020 has been fixed.

Scientists have used satellite data from the Copernicus Sentinel-2 mission, combined with the Sentinel-5P satellite, to detect individual methane emissions from space.

As a follow up to the news regarding the quality warning for SO2 and HCHO, it can now be confirmed that the background calibration is being correctly performed and that the quality of the near real time processing is no longer degraded from the 15 December.

On the Romanian Danube sector in South-Eastern Europe, sand and ice banks can present difficulties for ships navigating these waters—Copernicus Sentinel satellite images are used by local authorities, to monitor navigation and manage traffic.

Due to a ground segment configuration error, a set of NRTI data with sensing date of 2019-07-29 and 2019-07-30 that have been processed for validation of the the Near Real Time dataflow with improved algorithms have been mistakenly published on the Sentinel-5P pre-operations data hub on 2020-05-18/19.


A maintenance activity on the core infrastructure hosting the data hub services, is planned for 15 of December, from 07:00 to 15:00 UTC.
