🚨 Intelsat IS-33e Breakup Update 🚨 spacefluxHQ has been hard at work tracking about 40 fragments from the event. We detected multiple #fragments & UCTs during the observation session in this clip from our Cyprus sensor last night at 21-10-2024 17:43 (UTC). Stay tuned!


The first videos of the #asteroid #C0WEPC5 entry in #Russia are coming out on Telegram Messenger . It appears to be very similar to previous asteroid entires (2022 WJ, 2023 CX1, 2024 BX1). Lots of fragments at the end, it probably dropped some rocks in a remote forested area.

🎄 Celebrating our incredible team: Spaceflux Starlit Xmas Soiree 2024 ✨ We came together to celebrate our amazing team & the end of another fruitful year for spacefluxHQ. The evening was filled with joy, music, presents, & we even presented 3 awards for outstanding employees!


🚨 Breaking: spacefluxHQ detects debris cloud from Blue Origin 's New Glenn upper stage! Captured 17 Jan 2025, 12:54 UTC, likely from propellant release during passivation. 🛰️


Nova Lup 2025 (V462 Lupi) via Telescope Live Observatory (imaged on June 20, 2025. Unfiltered mag. about 5.5; animation with a POSS archive image via Tycho software ) Obs. E. Guido; M. Rocchetto; A. Valvasori #astronomy #novaLup2025 #astronomia

New Interstellar candidate NEOCP A11pl3Z imaged few minutes ago (02.5 July 2025, magn. 16.8 ) via spacefluxHQ network (Australia) OBS E. Guido, M. Rocchetto, J. Ferguson TEL 0.35-m f/3.0 reflector + CMO #astronomy #Interstellar


New image of interstellar object 3I/ATLAS = C/2025 N1 (ATLAS). A stack of 91 exposures, each 30 seconds long, was obtained on 2025 July 03.2 from X02 (Telescope Live Observatory , Chile) using a 0.61-m f/6.5 reflector + CMOS . The image shows a small, compact coma elongated toward PA 275
