Whenever I have come into large sums of money in my life, I always put half of it aside to spend on fast cars and the pursuit of loose women.

He can only "Infer" it because of the diffraction making the disk appear slightly elongated.

Quote:I have observed a number of transits during this Jupiter season. My eyes start playing tricks on me after staring through the telescope for a while. I was watching a bright/shadow transit of Europa and I swear I saw a momentary flash of bright light in the transiting shadow of Europa. Was it really there? Impossible to say, but I definitely perceived it and enjoyed it greatly. You may never know if what you perceived was real, even if others confirm that such a phenomenon is possible to observe. Remember the canals of Mars? I'm sure Giovanni Schiaparelli enjoyed seeing them, no matter the ultimate outcome of the observation./Ira
