A very good piece of news: ESA started distributing Sentinel2-B data on Copernicus hub, two months ahead of schedule. This is really an achievement !Here is ESA’s announcement :
Following the successful completion of the Sentinel-2B Satellite In-Orbit Commissioning Phase, we are happy to announce that access to Sentinel-2B Level-1C products will be opened to all users on 6 July .Access to Sentinel-2B products will initially be provided through a dedicated hub accessible via the Copernicus Open Access Hub home page with public credentials. This dedicated interface will be maintained until early September, at which point both Sentinel-2A and Sentinel-2B products will be commonly accessible through the nominal Data Hub interfaces.
Regarding Theia L2A production, we will have to wait for the availability of the data in PEPS, by end of July, and then perform some validation before releasing the data. Given the holiday period, it will probably happen in September. However, we have already checked that our L2A products, produced with MAJA withing MUSCATE should be great, as shown in this post some time ago:
