Galilean Moon Observation- November 30, 2014

As usual, I'm late in posting. Thanksgiving weekend was mostly cloudy, but early that Sunday morning was finally clear. I went out to observe the Jovian system from about 4:00 AM until about 6:00 AM.

Observing notes: November 30. 2014

Weather- 3:37 AM CST 51°F- 46°F wind chill
5:17 AM CST Salt Creek Commons 52°F- 46°F wind chill
Wind- South 12 MPH; 24 MPH gusts
Dew point 48°F

Here are Curt Renz's prediction times for Galilean events that morning.

Just missed Io shadow transit- ended 4:14 AM. Was observing before end of shadow transit, but not looking near limb, where shadows can be hard to detect.

Bad seeing, and got worse.

Watching as Europa separates from Jupiter's disk, after emerging from occultation.

All images are from my Galaxy SIII phone, afocally, and thus the poor quality. Also, Callisto, being so much farther from the Jovian disk was hard to image. I only captured it in a few images, seen below.

Io transit egress- first observed 5:25 AM CST.
Io separation- first observed 5:30 AM CST.

And that wrapped up my first prolonged Jovian observation since late spring.
