Mars rises in the east shortly after 4:00 AM, followed by Jupiter shortly before 6:00 AM. Venus rises around 6:30 AM, and quickly vanishes with the dawn's light
Saturn is just above the treetops to the southwest after sunset, and is visible for less than a half hour before it sets; a waxing crescent Moon sets a short while afterwards. The Moon should be an fairly good observing target on the evening of Thanksgiving day at 24% illumination. The Moon will be at first quarter on the 26th.
The sunspot group that I mentioned last week made it about half way around the face of the Sun before it faded from view. I created this video using two different frequencies from the Solar Dynamics Observatory - it shows that although the sunspot does seem to "evaporate," the magnetic disturbance associated with it continues to rotate around the face of the Sun.
Several prominences dance on the Sun's limb in 304 angstroms from the Solar Dynamics Observatory. You can also see a large "C" shaped filament off-center in the image - this is a prominence seen straight-down against the face of the Sun, instead of on the limb and against the blackness of space.
Only a faint ghost of the south-reaching coronal peninsula in the northern region remains this week, the southern coronal hole has diminished greatly in size, and the equatorial coronal hole has barely changed in position at all. SpaceWeather.com says: "Earth is beginning to exit a narrow stream of solar wind that arrived only a little more than 24 hours ago. NOAA forecasters say there is a 40% chance of G1-class geomagnetic storms on Nov. 22nd, decreasing to 20% on Nov. 23rd. Arctic sky watchers should remain alert for auroras tonight before the solar wind wanes."
