We report the detection of a radio burst from the newly discovered repeater FRB20220912A (ATel #15679) with the Medicina Northern Cross (MNC) radio telescope at 408 MHz. Observations were carried out with a 16 MHz bandwidth, ~14.5 kHz channel width and ~138 us sampling time. The MNC monitored FRB20220912A for 3 days, ~43 mins per day with similar starting times given by the transit of the source. The coordinates used for the observations were RA (J2000): 342.29 deg, Dec (J2000): +48.70 deg. The burst was detected on October 16th 2022 at 20:28:14 UTC (Barycentric Time of Arrival) and has ~65 Jy ms fluence and a 4.5 ms width. The fluence estimate takes into account the beam attenuation factor due to a off-centered detection (~20% at the burst time of arrival). The search was performed using the SPANDAK pipeline (Gajjar et al. 2018) spanning a DM range between 0 and 1000 pc/cm3 with Signal to Noise Ratio > 7. The best fit DM obtained from this blind search was 218.9 +- 0.8 pc/cm3, consistent with the one reported by CHIME/FRB in #ATel #15679. The link below shows the waterfall plot for this burst, coherently dedispersed at DM = 218.9 pc/cm3.
