I have from a very reliable source
 the current best estimate (as of Friday, September 5) of flyby time being 08:40:21.4 UTC. At that time it'll be 200.2 km from Mercury.My source has different orbital information -- is yours measured with respect to the ecliptic? I could also select "with respect to Earth mean equator" or "with respect to Mercury equator". These are with respect to the ecliptic: Semimajor axis: 7,596,000 before / 6,975,000 after Periapsis radius: 4,720,000 before / 4,523,000 after Eccentricity: 0.38 before / 0.35 after Inclination: 6.9 before / 7.0 after -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
