Thank you Arnold! So it was Terra... and it was a really bright flare, if the Iridium 61 was -2, Terra was at least -4 or -5!! ( I suppose that if both Terra and Ir61 are ~700km high , they have the same speed and then they spend the same time in each pixel aproximately). Does Terra flare regularly? Thank you Kevin and Rod too! Nice pictures! I did see a double flare... from a Noss pair (predicted by Simone), really nice. My limiting magnitude 3 (sometimes 3,5) skies allow me just to see planets and bright sats. Thank you to everybody! I am newbie seeing satellites and you really encourage me. Waiting for a double-double flare...
