The FRB 20251125A (RA=10:23:47.53, Dec=+09:51:24.74, DM=585.5) previously discovered in the POP (Piggyback Observation of Pulsars, https://fast.bao.ac.cn/cms/article/2034282224688386050) survey was found to be repeating.
We detected 7 bursts in a 1-hour tracking on 20260714, 21 bursts in a 4-hour tracking on 20260715, with the S/N of all bursts higher than 7. We are trying to get a more accurate position of the source with FAST and several elements of the FAST core array.
This work made use of the data from FAST (Five-hundred-meter Aperture Spherical radio Telescope) (https://cstr.cn/31116.02.FAST). FAST is a Chinese national mega-science facility, operated by the National Astronomical Observatories, Chinese Academy of Sciences.
