The payload on OPUD‑293 was a Fourier Transform Infrared (FTIR) spectrometer capable of resolving molecular absorption lines down to 0.01 cm⁻¹. In the 12‑minute window, the instrument recorded over 4 300 000 individual spectra, each containing:
| Platform | Preferred Player | Reason | |----------|------------------|--------| | Windows | VLC Media Player | Wide codec support, no extra codecs needed. | | macOS | IINA or VLC | Native‑look (IINA) or robust (VLC). | | Linux | MPV or VLC | Low‑resource, command‑line control (MPV). | | Mobile (iOS/Android) | Plex, VLC for Mobile, or a local video player that supports MKV/HEVC. | Handles most containers without conversion. | OPUD-293-JAVHD-TODAY-0326202402-12-06 Min
Pro tip: If you use Plex or Jellyfin as a personal media server, add the folder to the library; the server can transcode on‑the‑fly for devices that don’t support the original codec. The payload on OPUD‑293 was a Fourier Transform
Solar flare SFX‑2423 erupted at 02:58 UTC, sending a burst of extreme ultraviolet (EUV) radiation toward Earth. This surge temporarily altered the photochemical balance in the stratosphere, boosting the production of odd‑oxygen (O₃)* and hydroxyl radicals (OH). The 12‑minute observation captured the onset, peak, and early decay of those changes—something that had never been recorded at such temporal resolution. Solar flare SFX‑2423 erupted at 02:58 UTC, sending
