Thought it was Google. No. Reserved but not registered. Looks like a FED Contractor. Any ideas what it is?
Odd. Looks like a balloon ... guessing that's Google Project Loon associated company. https://ravenaerostar.com/about/project-loon https://ravenaerostar.com/
Did you check the history? It launches and comes back down. Has not spent any meaningful time in the air, and is not actually registered with the FAA. The flight history before this specific launch shows that, currently its aloft similar to loon. A Hold is not an active registration. Not to mention the same company provides balloon services for the gov and mil. Does not seem like it is a loon to me.
FAA is slow to update. Sometimes they are 3+ months behind. You get a pink slip that acts as airworthiness certificate. I once had a plane registration take 11 months to process.
It's entirely possible it is some mil or otherwise project as well. I wouldn't discount that the FAA is inefficient, it's US government and they are above Veteran Affairs office but not by much. Registration might update. The assigned it an N-number which usually isn't required for Military.
It was a Long duration balloon developed by Raven Industries called "thunderhead"... hence the TH after the number. They are related to Google's Loon Project but being developed by the company alone...
