In the Sky this Week – September 13, 2022

Morning: Venus appears low above the Eastern Horizon at sunrise – appearing a bit lower, and a bit more eastward each morning.

Evening: Jupiter rises in the east after sunset, and Saturn appears high above the southeastern horizon.

Early Morning: Jupiter appears high in the southern sky after midnight, and Saturn appears above the southwestern horizon.

Morning: Jupiter fades into the dawn above the western horizon.

Evening: Mars rises to the east-northeast shortly before midnight.

Early morning: Mars appears near the star Aldebaran a few hours before sunrise, both of them appearing high above the east-southeastern horizon

Early morning: The Moon appears near Mars, Aldebaran and the Pleiades high in the southern sky before sunrise on Sept. 16th

Predawn: The Moon will have moved between Mars and the star Elnath in the predawn sky on Sept. 17t

Predawn: The Moon will appear near the star Pollux in the predawn sky on Sept. 20th.

• The Moon is a Waning Gibbous – rising after sunset, visible high in the sky after midnight, and visible to the southwest after sunrise.
• The Third Quarter Moon occurs on September 17th – rising around midnight, and visible to the south after sunrise.
• After September 17th, the Moon will be a Waning Crescent – visible low to the east before sunrise.

Moon News

The Sun has eight named sunspots, again – AR3101 is VERY active, and rotating out of view.!

Spaceweather.com says: “IT’S BAAAACK: Active sunspot AR3088 has returned after a two-week trip around the farside of the sun. In August, Earth dodged a fusillade of CMEs from the explosive spot, So it hammered Venus instead. The returning sunspot seems to have decayed since we last saw it, but it may still pose a threat for strong flares.”

Amateur Solar Astrophotography

“On the morning of this Saturday, September 10, I was able to photograph in detail this huge filament, which is approaching the solar limb, and which for a week has been accompanying sunspot AR3092 on its journey across the surface of our star.

Undoubtedly, it is giving us a great show during these days where no large sunspots or prominences were observed.

To take this picture I used a Sky Watcher Evostar 150ED telescope, a Baader energy rejection filter, a Quark Chromosphere filter, and a Player One Apollo-M Max camera.”

Messier Tour: M28

Messier 28 (M28) is a class IV globular star cluster located in the constellation Sagittarius. The cluster has an apparent magnitude of 7.66 and lies at a distance of 17,900 light years, or 5,500 parsecs, from Earth. Its designation in the New General Catalogue is NGC 6626.

Messier 28 is quite easy to find in the sky as it lies less than a degree northwest of Kaus Borealis, one of the bright stars forming the Teapot asterism in Sagittarius. However, as M28 is not particularly bright, it is invisible to the naked eye and only appears as a faint patch of light in binoculars.

Small telescopes will show a nebulous object occupying an area of 11.2 arc minutes in apparent diameter, while medium-sized and larger telescopes will reveal the cluster’s bright core and resolve the stars.

Individual stars can only be seen in 4-inch and larger instruments. – messier-objects.com

Messier 28 is considerably smaller than the neighbouring Messier 22. It is a class IV globular cluster, which means that it has intermediate rich concentrations of stars and that the stellar density at the core region is visible, but slightly spread out.

Messier 28 was the first globular cluster discovered to contain a millisecond pulsar, a pulsating, highly magnetized rotating neutron star emitting a beam of electromagnetic radiation with a rotational period between 1 and 10 milliseconds.

The pulsar, catalogued as PSR B1821–24, was discovered in 1986 using the Lovell Telescope, a radio telescope at Jodrell Bank Observatory in Cheshire, England.

Researchers later discovered 11 more millisecond pulsars in the same area, which makes M28 a cluster with the third largest population of pulsars, after the globular clusters Terzan 5, also located in Sagittarius, and 47 Tucanae in Tucana constellation. – messier-objects.com

Location of M28 in the Milky Way

M28 is above the above the galactic disk, and close to the galactic bulge.

Here’s my obligatory “What would a planet look like if it were near that Messier object” pic:
