PLANETS
Mercury was at superior conjunction last week and is lost in the Solar glare all this week.
Venus is currently in Libra and is a bright evening star at Sunset all this week.
Mars rises in Gemini in the early hours from Northern latitudes and is close to the Zenith from Southern latitudes.
Jupiter is in Taurus this week nestled between the horns of the bull.
Saturn is in Aquarius this week, rings continuing to close.
Uranus in Taurus this week just a couple of degrees to the West of the Pleiades
Neptune is close to the circlet of Pisces this week and follows Saturn across the sky as the night progresses.
COMETS
C/2023 A3 (Tsuchinshan-ATLAS) has brightened to magnitude 2.2 this week. Visible from southerly skies in the morning twilight. A challenging target from Northern latitudes.
C/2023 A3 (Tsuchinshan-ATLAS)
Magnitude: 2.2 Still Brightening
Coma Diameter: 5.0' Tail Length: 30.0'
Apparent: 10h 55m 13s -06° 04’ 26” in Leo
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.
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. If you can block it out of your FOV you might have a shot at open cluster Gaia 1 (https://en.wikipedia.org/wiki/Gaia_1)
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. Now a challenging evening target on the Western horizon after Sunset, still visible above 10° for a couple of hours from Northern locations. T Coronae Borealis, or T CrB, last exploded in 1946 and astronomers believe it will do so again in 2024. Once in a lifetime event! Plan ahead just in case! Full article here. The TSS TCrB Citizen Science Thread is here.
SPACE LAUNCHES
Two planned launches this week. Info from spaceflightnow.com
September 29/30 Falcon 9 • OneWeb 20
Launch time: 11:54 p.m. PDT (2:54 a.m. EDT, 0654 UTC)
Launch site: SLC-4E, Vandenberg Space Force Base, California
A SpaceX Falcon 9 rocket will carry the final batch of OneWeb’s Gen 1 satellites to low Earth orbit. Nearly eight minutes after liftoff from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base, the Falcon 9 first stage booster, tail number B1082, will return for a touchdown at Landing Zone 4 (LZ-4).
October 4 Vulcan • Certification Flight 2
Launch time: Three-hour window opens 6 a.m. EDT (1000 UTC)
Launch site: SLC-41, Cape Canaveral Space Force Station, Florida
The second flight of United Launch Alliance’s Vulcan rocket will carry ballast and a collection of small payloads. ULA changed this mission when it became clear the original payload, Sierra Space Dream Chaser cargo ship, would not ready for launch. This second test flight is needed to gain certification from the U.S. military to fly national security payloads. Delayed from September 2024.
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.
