Meteor shower output caused by comet 15P/Finlay

International audience Theoretical work on the meteoroid stream ejected by comet 15P/Finlay predicts multiple outbursts in 2021 in agreement with previous authors. This work predicts the first outburst to happen around 2021-09-29T08:35 UT, for a radiant located at α = 260.8 deg δ = −57.4 deg and wil...

Description
Summary:International audience Theoretical work on the meteoroid stream ejected by comet 15P/Finlay predicts multiple outbursts in 2021 in agreement with previous authors. This work predicts the first outburst to happen around 2021-09-29T08:35 UT, for a radiant located at α = 260.8 deg δ = −57.4 deg and will be best visible from New-Zealand. The second will happen on 2021-10-07T 00:35 UT, followed by a third on 2021-10-07T03:55 UT. They will be best visible from the tip of Antarctica or Tierra Del Fuego (Argentina). The level of each outburst is evaluated based on the photometry of the comet, which is known to have experienced some outbursts, but is less certain than the timing of each event.
