I believe I spotted the Centaur (1999-023B 25725) from the recent Milstar launch from my driveway. (roughly 28.5N, 80W). It was headed from the Soutwest to the East in fairly clear skies with light scattered clouds and a typical suburban environment. Limiting magnitude was about 3-4. I didn't see enough stars to get any position measurements. Special thanks to Tony for his excellent element sets which made my observation possible. I also saw by chance Cosmos 1143 r before. A quick glance showed me it was travelling from South to North and couldn't be the Centaur in question. No special appearance or flashing noted for either object, but I'm not a very experienced night sky observer.
