Ah, I see the error. I mistyped the name (should be ERMINAZ-2U), even though I just put it in the SATCAT. Sigh...

This makes it sound like they are 3 identical satellites: www.nanosats.eu/sat/erminaz-2. I guess we'll see.

Items in brackets are an object type, like [GLONASS]. DTC is what SpaceX asked us to use (rather than D2C) for that part of their Starlink constellation. This is described in our SATCAT documentation at: celestrak.org/satcat/satca.... It helps discriminate a subset of a particular constellation.

We are still universally blocking SupabaseEdgeRuntime/1.74.x. But we will remove 35,251 IP addresses using those versions earlier in the month, as well. If you haven't upgraded to 1.76.0 or above yet, you should do that ASAP or you will be sent back to the firewall.

041

T.S. Kelso @tskelso.bsky.social · 01/10/2026

After gradually approving current variants of SupabaseEdgeRuntime/1.76.0 and above and seeing no problems, we are in the process of removing 50,105 IP addresses for those from the firewall.

020

T.S. Kelso @tskelso.bsky.social · 29/09/2026

We strongly encourage all software developers to include an e-mail address in their user agent, so that if we find problems, we can contact them and get the issues rectified before a universal block might be required.

020

T.S. Kelso @tskelso.bsky.social · 29/09/2026

For those that do, we will go back and remove other users of that specific variant from the firewall, with the hope of removing some of the tens of thousands of IP addresses that have ended up there because of the need to implement a universal block to keep CelesTrak functioning.

020

T.S. Kelso @tskelso.bsky.social · 29/09/2026

After a month of optimizing our firewall handling and cleaning up temporary processes, we now have a way to 'approve' SupabaseEdgeRuntime variants. We are starting with those including an e-mail address in the user agent. We will be carefully watching their adherence to our user policy.

T.S. Kelso @tskelso.bsky.social · 28/09/2026

We have not worked out the formatting for the pre-launch state vectors yet (and adapting software). But we are getting ephemerides and processing that normally. I think pre-launch was pretty low priority for this launch, but SpaceX is committed to continuing to provide this through CelesTrak.

030

T.S. Kelso @tskelso.bsky.social · 28/09/2026

Sorry for the delays in getting this data out, as we are continuing to work with SpaceX to automate this processing. As a consolation, here's a cool bonus view of the last Starlink satellite being deployed, as seen from the 25th deployment.
