Detection of 15 bursts from FRB 180916.J0158+65 with the uGMRT

Understand

We report the findings of a uGMRT observing campaign on FRB 180916.J0158+65, discovered recently to show a 16.35-day periodicity of its active cycle.

• We observed the source at 550-750 MHz for $\sim 2$ hours each during three successive cycles at the peak of its expected active period.
• We find 0, 12, and 3 bursts respectively, implying a highly variable bursting rate even within the active phase.
• We consistently detect faint bursts with spectral energies only an order of magnitude higher than the Galactic burst source SGR~1935+2154.
