The 4th observing run of the LIGO-Virgo-KAGRA network has officially come to an end. However, before the long commissioning break prior to the 5th observing run, there will be another short observing run called IR1 (Intermediate Run 1). This is currently planned to start in mid-January 2027. In the coming months, we'll also be retiring a large number of glitches from the project, leaving behind ones whose classifications are more uncertain.
