We report the detections of bright fast radio bursts from FRB 20220912A using the Westerbork-RT1 25-m telescope at 332 MHz. After the discovery of the highly active repeater FRB 20220912A by CHIME/FRB (ATel #15679), we started a high-cadence monitoring campaign using 25-m and 32-m class European radio telescopes

Hessels (j.w.t.hessels@uva.nl)Subjects: Radio, Fast Radio BurstTweetWe report the detections of bright fast radio bursts from FRB 20220912A using theWesterbork-RT1 25-m telescope at 332 MHz. After the discovery of the highly active repeater FRB 20220912A by CHIME/FRB (ATel#15679), we started a high-cadence monitoring campaign using 25-m and 32-m classEuropean radio telescopes. We have been observing the source almost daily at C-, L-,and P-band using the Stockert (Germany), Westerbork (Netherlands) and Torun(Poland) radio telescopes. Depending on availability of the telescopes we observesimultaneously at complementary wavelengths. Additionally we have had overlappingcoverage with the LOFAR Core stations in the Netherlands and the international IE613LOFAR station in Ireland. Here we report the discovery of four bright bursts detected during 156 h of observing atP-band. Observations were conducted at a central frequency of 332 MHz with abandwidth of 64 MHz using the Westerbork RT-1 radio telescope. We have a significantdrop in sensitivity in the top 8 MHz and therefore mask these channels. The receiver hasa system equivalent flux density (SEFD) of 2100 Jy.

Each of the four detected bursts had overlap with a subset of the following observations,where we found no counterparts: 151 MHz (VHF-band, IE613 LOFAR station), 1.37 GHz(L-band, Stockert), 1.41 GHz (L-band, Torun) and 4.6 GHz (C-band, Torun). We canplace an upper limit on the fluence assuming an 8-sigma 1-ms detection threshold of 30Jy ms, 7 Jy ms, 14 Jy ms and 11 Jy ms, respectively. During our campaign we have also detected many tens of bursts at 1.4 GHz (L-band)ranging between 10-1000 Jy ms while no bursts were found at 4.6 GHz (C-band) inhundreds of observing hours, see also ATel #15727. The analysis of all detected bursts,in both L- and P-band, are currently in preparation as part of a forthcoming paper.
