The strong glitches have been there all week, with varying intensity/frequency over time. See for instance https://scientists.virgo-gw.eu/DataAnalysis/UPV/2025/20250126/last_week_1421276422-1421881222/V1:Hrec_hoft_16384Hz/perf/V1-Hrec_hoft_16384Hz-all_freqtime.png (Omicron glitchgram over a week) and https://scientists.virgo-gw.eu/DataAnalysis/UPV/2025/20250126/last_week_1421276422-1421881222/V1:Hrec_hoft_16384Hz/perf/V1-Hrec_hoft_16384Hz-veto6_freqtime.png (after an UPV veto based on V1:INJ_IMC_TRA_DC, representative of many related INJ channels).
