Made an observation on an emersion of one of Jupiter's satellities.
I obtained an emersion of the first satellite under favorable circumstances, the night being still and clear.
At three in the morning I obtained an observation of an emersion of the first satellite of Jupiter, with other observations.
I obtained, with other observations, an immersion and emersion of the third satellite.
A more miserable-looking object, on his emersion from the cold bath, I never saw.
At about ten, I observed an emersion of Jupiter's second satellite; time by the achrometer 8.
After about the middle of the totality, and so after the emersion of the sun, we saw Venus very plainly, but no other star.
We were sitting together last night in the turret of his house, watching the emersion of a satellite of Jupiter.
