Mars
Continues its climb on the ecliptic and brightening, passing the border from Aries into Taurus on the 11th. Compare its red hue to nearby Aldebaran and Betelgeuse.

Jupiter
Continues its rise on the Eastern horizon at Sunrise this month and becoming ever more prominent in the morning twilight.

Saturn
Is visible and starting to get higher in the East pre dawn sky.

Uranus
Continues to rise in the morning sky in the constellation of Taurus.

Neptune
Is visible in the overnight and morning hours in the constellation of Pisces.

STARS

Zeta Herculis - An unequal binary pair with a highly eccentric 35 year orbit. Currently at maximum separation. Zeta Herculis is the star at the bottom right of the Hercules keystone asterism. And for a bonus point, can you spot the Minor Planet Pallas passing by to the south of Zeta Herculis? It will be at opposition on the 19th June.

Sirius - Have you ever tried for Sirius B? Sirius A and B are now at their widest apparent separation in their 50-year orbit, 11 arcseconds apart, and will remain so for the next couple years before they start closing up again.

T Coronae Borealis - A star system, located 3,000 light-years away from Earth, is predicted to become visible to the unaided eye soon. This could be a once-in-a-lifetime viewing opportunity as the nova outburst only occurs about every 80 years. T Coronae Borealis, or T CrB, last exploded in 1946 and astronomers believe it will do so again between February and September 2024. Once in a lifetime event! Plan ahead just in case!

INTERNATIONAL SPACE STATION

We highly recommend using "Spot the Station" from NASA to find out when the International Space station will be passing over your location. This is a fun object to see flying high above, try using binoculars here, lots of fun!

For the HAM radio enthusiasts among you, please keep a eye on the ARISS website for upcoming contacts or SSTV broadcasts for when the International Space Station is within range. There are several HAMS on board the ISS, they should have a busy radio schedule coming up. AMSAT are another great resource in this regard.

This video is from the ISS live feed on YouTube. Watch live video from the International Space Station, including inside views when the crew aboard the space station is on duty. Views of Earth are also streamed from an external camera located outside of the space station. During periods of signal loss due to handover between communications satellites, a blue screen is displayed.

Thanks to the team for posting.

Reference Sirius - if you can block it out of your FOV you might have a shot at open cluster Gaia 1

From Wikipedia
"Gaia 1 is an open cluster of stars discovered in 2017 by astronomers using data from the Gaia Space Observatory. It is a high-mass and bright cluster, but remained unseen in prior astronomy due to veiling glare in ordinary telescopes overwhelmed by the star Sirius, which lies 10 arcmins west.[2] Its half-light radius is about 29 light-years (9 pc), assuming a distance of 15,000 light-years (4,600 pc), and it has an estimated mass of about 22,000 M☉.[1] "

For the full article:https://en.wikipedia.org/wiki/Gaia_1

ACD 75 Astro Mutt - Rest in Peace Wubby
"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects." - Robert A. Heinlein
