Additional note: Heavens above seems to predict fainter then mag 4 for the lower passes as well which is very plausible. For the favorable 86° pass this evening it predicts mag 3.7 and Calls-ky mag 4.4) Ralf ----- Original Message ----- From: "Ralf Vandebergh" <ralf.vandebergh@home.nl> To: <seesat-l@satobs.org> Sent: Tuesday, August 24, 2010 10:50 AM Subject: magnitude question Agena-D > Hi all, > > The comming days I will be hunting to capture HR images of an Agena upper stage Agena D Rocket > (00733 1964-002-A). which will be passing a few days favorably from my location. > > Problem is I get 2 different magnitude-predications.
