Electrons made on the wrong side of Earth's 'impenetrable barrier', a gamma-ray burst that only looked weak, the week that was, and a Halloween that is astronomically a week early. The Wall That Broke In 2014 NASA's Van Allen Probes revealed a sharp inner edge to Earth's outer radiation belt: electrons at the very highest energies never got closer than about 2.8 Earth radii. During the May 2024 superstorm — the biggest since the 2003 Halloween storms — Japan's Arase satellite saw electrons of about 3 MeV rise deep inside that 'impenetrable barrier'. A new paper led by Yoshizumi Miyoshi (Nagoya University ISEE) shows a peak in electron phase space density growing in place at L* ≈ 3, about 12,000 km up — evidence the electrons were accelerated there rather than carried in. Intense chorus waves, operating in a region emptied by a crushed plasmasphere and a negative ionospheric storm, are the likely engine. Caveats: one storm; 'consistent with' chorus acceleration; the breach itself had been reported before — the new part is the mechanism. Not Faint, Just Side-On GRB 260310A, caught by Fermi on 10 March 2026, had a feeble gamma-ray flash but one of the brightest afterglows ever seen. Yu-Han Yang (Tor Vergata) and colleagues argue we viewed a two-component jet from the side. Preprint from May; published in ApJL this month; competing models exist. The Week That Was E214 GRB 160425A, one burst with two births · E215 θ¹ Ori C, the star born twice · E216 Rubin's first dwarf-planet candidate 2026 ED138 · E217 Betelgeuse pulled out of round by Siwarha · E218 Teghaza 001, one of the oldest pieces of Mars. Plus Swift's re-entry watch, Voyager 1 at one light-day on 18 Nov, and Starship Flight 15 targeted for November. Skywatch Halloween is astronomically a week early (true cross-quarter 7 Nov). Mars, Jupiter and Regulus line up before dawn, Mars–Jupiter just over 1° apart on 16 Nov. Moon near Mars and Jupiter on the mornings of 2–3 Nov. Saturn rules the evening, best from the south. US clocks fall back 1 Nov. Solar viewing only with ISO 12312-2 certified filters.
