A veritable riot of conjunctions is happening all week in the eastern predawn skies; Venus is VERY close to the star Regulus, and Mercury and Mars continue to be low in the sky before sunrise.
These conjunctions can also be seen from the southern hemisphere; note how the position of the planets differs from the northern hemisphere.
Saturn continues to be a good observing target in the southern skies after sunset.
The southern skies seen from Perth after sunset are something I’d REALLY like to see; visible are the two Magellanic Clouds, the Carina Nebula
In the eastern sky seen from Perth at 1:00 AM on Sept. 18th we see a good example of the different orientation of constellations seen from the southern hemisphere.
The Pleiades star cluster can be seen high in the eastern sky at 2:00 AM.
The Pleiades open star cluster consists of approximately 3,000 stars, and is among the nearest star clusters to Earth; the cluster is easily visible to the naked eye.
This video shows a faster-than-light trip through space to the Pleiades star cluster:
SpaceWeather.com says that “Lonely sunspot AR2680 poses no threat for strong solar flares.”
There is a large coronal hole that can be seen in 211 angstrom s.
