I don't know. Remember, it is a prediction not an observation. For questions about the prediction model and its accuracy, you would have to contact NOAA. CelesTrak does not generate this data, it only makes it easily available and there is a link to the source for more info.

Note: The GP data for this object is invalid since it significantly violates several of the key assumptions used in the development of SGP4. It is actually in a heliocentric orbit on the way to Mars. It has been marked as such on CelesTrak and no GP data will be returned.

CelesTrak has GP data for 1 object from the launch (2025-260) of ESCAPADE atop a New Glenn rocket from Cape Canaveral on Nov 13 at 2055 UTC: www.nasa.gov/news-release.... Data for the launch can be found at: celestrak.org/NORAD/elemen....

Elevated conditions continue. Perhaps a good time to look for enhanced Northern & Southern Lights.

NOAA is reporting and predicting elevated geomagnetic activity: celestrak.org/SpaceData/. Expect to see increased prediction errors in all LEO orbital data.

18 SDS has cataloged 10 objects from the launch (2025-258) of Guowang Group 13 atop a Long March-12 rocket from Wenchang Space Launch Site on Nov 10 at 0241 UTC: www.china-in-space.com/p/guowang-re.... SATCAT data can be found at: celestrak.org/satcat/table....

Note: For some reason, 18 SDS incorrectly shows the first 3 objects launched from JSC instead of YSLA, like the rocket body.

18 SDS has cataloged 4 objects from the launch (2025-255) of Shiyan-32 01-03 atop a Long March-11 rocket from waters off Shandong Province on Nov 8 at 2101 UTC: www.china-in-space.com/p/anonymous-.... SATCAT data can be found at: celestrak.org/satcat/table....

CelesTrak has ephemeris-based SupGP data for all 29 satellites from the Starlink G6-87 launch (2025-259) atop a Falcon 9 rocket from Cape Canaveral on 2025-11-11 at 03:21:30 UTC: spaceflightnow.com/2025/11/10/l.... Data for the launch can be found at: celestrak.org/NORAD/elemen....

That means we have no GP data from USSF for the last SIX launches--except for the SupGP produced by CelesTrak for the last 3 Starlink launches. And there are 5 more launches--3 of them Starlink--scheduled before the end of the week: new.nextspaceflight.com/launches/?q=....

The latest 18 SDS GP data meltdown continues. Almost all of the data is over 2 days old and the mean age is at 3.07 days old. And 4,437 of the 10,087 RSOs we have SupGP data for have an 18 SDS RMS of over 25 km. No doubt the other 18,872 RSOs have data just as bad. Why is this even condoned?

The current GP statistics can be found at: celestrak.org/NORAD/elemen.... The current SupGP vs. GP Comparisons can be found at: celestrak.org/NORAD/elemen....

With the latest dropout of 18 SDS GP data, the mean age of the data is now over 2.4 days old and almost nothing has been updated in the past day. The result is that 3,782 objects with SupGP data have an 18 SDS GP RMS difference of over 25 km--7 more than 10,000 km RMS.

CelesTrak has ephemeris-based SupGP data for 28 of 29 satellites from the Starlink G10-51 launch (2025-257) atop a Falcon 9 rocket from Cape Canaveral on 2025-11-09 at 08:10:10 UTC: spaceflightnow.com/2025/11/07/l.... Data for the launch can be found at: celestrak.org/NORAD/elemen....

I'll end this thread with this: When you--and especially USSF leadership--dismiss these 'little' errors, you are enabling complacency. There are serious issues with the GP, SP, and CDM data being ignored, as well, as shown at: celestrak.org/publications.... This won't end well for space safety...

And then 18 SDS effectively changed the catalog numbers for the cross-tag. Once SpaceX changes to use those, the data STILL won't match. SpaceX knows which object is which and 18 SDS needs to match their IDs.

This stuff makes my head hurt. And it happens almost every day. Now you know, too...

Today's other errors include "STATLINK" for SSC 66146 and assigning the wrong launch site for all of 2025-240 and adding an extra "9" in the name for SSC 66193 (manual editing rather than M2M).

18 SDS 'fixed' this problem by changing SSC 66177 to STARLINK-35352. But they didn't change 2025-242C to 2025-243A, the Owner to US, or the launch site to AFETR.

In our update process, yellow shows changes, which is how we catch most errors. The non-changes almost slipped through...
