We report on the lowest-frequency detection to date of three bursts from FRB
180916.J0158+65, observed at 328 MHz with the Sardinia Radio Telescope (SRT).
The SRT observed the periodic repeater FRB 180916.J0158+65 for five days from
Feb. 20, 2020 to Feb. 24, 2020 during a time interval of active radio bursting,
and detected the three bursts during the first hour of observation; no more
bursts were detected during the remaining ~ 30 hours. Simultaneous SRT
observations at 1548 MHz did not detect any bursts. Bursts fluences are in the
range 37 to 13 Jy ms. No relevant scattering is observed for these bursts.

We also present the results of the multi-wavelength campaign that we
performed on FRB 180916.J0158+65, during the ~ 5 days of the active window.
Observations on different time spans were performed simultaneously with the SRT
observations with the Northern Cross at 408 MHz, with XMM-Newton, NICER,
INTEGRAL, AGILE and with the TNG and two optical telescopes in Asiago, which
are equipped with fast photometers. XMM-Newton obtained data simultaneously
with the three bursts detected by the SRT and determined a luminosity upper
limit in the 0.3-10 keV energy range of $sim10^{45}$ erg s$^{-1}$ for the
burst emission. AGILE obtained data simultaneously with the first burst and
determined a fluence upper limit in the MeV range for millisecond timescales of
$ 10^{-8} rm , erg , cm^{-2}$.

Our results sensibly constrain the broad-band emission from FRB
180916.J0158+65, and provide the best limits so far for the electromagnetic
response to the radio bursting of this remarkable source of fast radio bursts.
