A power outage affected up to 600,000 subscribers in Zhukovsky, Lytkarino, and Ramenskoye in the Moscow region over the past 59 minutes from 4:46 p.m. to 5:45 p.m. UTC on Dec. 30, which local authorities attributed to a substation accident while noting an unmanned aerial danger in the areas, according to Exilenova+ and Supernova+ channels. Supernova+ reported images capturing the moment of the substation lighting up in Ramenskoye, with parts of the city without power, and pictures from Moscow suburbs showing blackouts persisting for over an hour. Exilenova+ stated the light disappeared in these locations, affecting hundreds of thousands, amid ongoing unmanned danger. Радар ВРВ reported multiple fixations in the direction of Kaluga and nearby areas during the reporting window, advising compliance with safety measures. Separately, Exilenova+ indicated that an attack by unknown UAVs on occupied Melitopol continues, leaving the city without power. These developments follow a Ukrainian drone attack on Moscow reported underway in the previous hour from 3:46 p.m. to 4:45 p.m. UTC, with numerous fixations west-south-west of the Moscow region, according to Russian radar channel Радар ВРВ and Sentdefender on X.
