Visibility III / V
At 20.59 I read in the Stars 2015 guide that the passage of the Europa Moon had started at 19.59.1. The weather was clear, so I headed south to my balcony and headed for my Skywatcher 127 telescope toward Jupiter.
My observation site is in the city center, so it is light polluted. Jupiter was moderately low above the sawdust field of a brightly lit paper mill, but that didn’t seem to bother. Seeing was about 3-4. A stirring with intermittent clear periods of a few seconds.
The observation period was approximately 21.05–21.20. With the 32mm eyepiece I used, Europa did not stand out, but the shadow of Europa occasionally stood out spot-like clearly as the atmosphere calmed down for a moment. The red color of the Io moon near the edge of Jupiter also stood out well.
With the 2 x Barlow lens and the 32 mm eyepiece, the shadow stood out worse, the Europa still didn't stand out.
Detection devices: Skywatcher 127, eyepiece 32 mm, 2 x Barlow lens, manual tracking
