The Solar Astronomy Laboratory of the Space Research Institute of the Russian Academy of Sciences captured a video showing comet 3I/ATLAS moving alongside a star. Overnight from October 21 to 22, the comet experienced a powerful plasma eruption from the sun, marking one of the strongest events in the current 25th solar cycle.

Following the incident, the comet 3I/ATLAS has moved out of the LASCO instrument's field of view, making further observation of its movement impossible. The next opportunity to observe this interstellar comet from Earth is expected to be in mid-November.
