We report the detection of four radio bursts from the repeating FRB 20220912A (ATel #15679) with the Medicina Northern Cross (MNC) radio telescope. Observations were carried out at 408 MHz with a 16 MHz bandwidth, ~14.5 kHz channel width and ~138 us sampling time. The coordinates used for the observations were (R.A. J2000, Dec. J2000) = (23:09:04.9, +48:42:25.4), provided by DSA-110 (ATel #15716, Ravi et al. 2022). The MNC is monitoring FRB 20220912A daily since 2023/05/17, ~ 40 mins per day with similar starting times given by its transit, collecting a total of 22.3 hr on source. The search was performed using the SPANDAK pipeline (Gajjar et al. 2018), spanning a DM range between 200 and 240 pc/cm3 with a Signal to Noise Ratio > 7. The bursts properties are reported in waterfall plots at the link below. The four bursts we report have been detected in the last 2 weeks of observations. We note that no bursts from this source have been reported since December 2022 (ATEL #15817, Zhang et al. 2023), hence these detections may suggest a renewed activity of the source. The MNC monitoring of FRB 20220912A is still ongoing. We encourage a rapid multiwavelength follow up of the source.
