Would love to see a launch also John. Very nice observation!
Another interesting observation appears in the SOHO C3 camera video (2 posts back) covering the last 3 days. On the 20th Mercury appears at the 10 o’clock position and moves to the right against the background stars of Capricorn. As it does it appears to disappear! So little of its surface is illuminated today as it passes through inferior conjunction explaining its vanishing act!
