Whatever is currently happening with comet C/2024 S1 ATLAS is remarkable. On October 19 at 3:00 UT it was 7m5 bright, showed a strongly condensed 230” coma and an ion tail at least 1° long in PW 258. The next few hours will show whether this is the final outburst. The observation was made with the 12"/f-3.6 ASA astrograph on the Tivoli farm in Namibia. Total exposure time 15 minutes.  The value of the brightness measurement in the green filter is 7m5, that in the entire spectrum 8m1
