We report on joint observations of FRB 180916.J0158+65 with the Sardinia Radio Telescope (SRT) and the Medicina Northern Cross (MNC) during its active phase, as predicted by the recent work by the CHIME/FRB Collaboration (The CHIME/FRB Collaboration 2020, Nature, in press).
Observations were carried out daily by the MNC from February 3rd to February 8th (included) for one hour during transit, starting at 15:43 UT on the first day and 4 minutes earlier each following day. The MNC observes at 408 MHz with a 16 MHz bandwidth, a 781 kHz channel width and a 138 us sampling time.
The SRT observed the source for two days at the onset of the active window. Observations performed on February 3rd were carried out at C-band (6.3-7.3 GHz) for two hours, starting at 17:48 UT and overlapping with observations with the Swift telescope (ATel #13446). Observations on February 4th were performed at L-band (1.5-1.8 GHz): first between 16:05 and 17:08 UT, simultaneously with Swift observations, and then between 18:11 and 19:11 UT, partially overlapping with observations (fast photometry) carried out in the optical band with the Galileo and Schmidt telescopes at the Asiago observatory (ATel, to be submitted). A 125 us sampling time and 1-MHz channel width were used.
During our observations, no burst was detected down to a 1 sigma rms sensitivity of 500 mJy for the MNC, 30 mJy for SRT at L-band and 200 mJy for SRT at C-band, respectively, assuming a burst duration of 1 ms. Additional refined analysis is ongoing.
