Walmart exclusively announced on "Good Morning America" that it is combining its Walmart+ and Sam's Club Plus memberships into a new $120 annual offer, a move the retailer says could save shoppers nearly $100 a year. Read more: abcnews.link/KOfm8pF

FWIW, someone on Facebook came up with these frequencies. They look like they're from the old STS days, but if you're in the San Diego area it won't cost you any money to have your receiver do a memory scan. 296.800 (AM) 259.400 (AM) 259.700 (AM) 279.000 (AM)
During the final phase of re-entry and splashdown, how will #Artemis2 be talking to the ground? TDRS? UHF AM simplex? If it’s the latter, anyone have suggestions of frequencies to monitor from Southern California?

Tonight, Starlink 17-35 will launch from Vandenberg and will generate a highly visible 'twilight effect' in the sky! If you are located within the purple shaded area, make sure to catch it! Launch weather is looking problematic, specifically due to upper-level winds and clouds.

A SEVERE (G4) or EXTREME (G5) geomagnetic storm remains POSSIBLE TONIGHT – Wednesday, November 12, 2025. Make plans now to hunt for the aurora borealis with your loved ones! This would be realized if we have favorable timing with the “grand finale” CME, or coronal mass ejection — a magnetic shockwave. If it hits too early, we might only get the tail end of the geomagnetic storm at dark. You might also catch a rogue Taurid meteor! The meteor shower doesn’t produce many meteors, but rather a few sporadic shooting stars that can be fairly bright!
