Tau Herculids

The Tau Herculids are a meteor shower that when discovered in 1930 appeared to originate from the star Tau Herculis. The parent comet of the Tau Herculids is periodic comet Schwassmann-Wachmann 3 with a 5.4 year orbital period. This meteor shower occurs from May 19 - June 19. The meteor shower was first observed by the Kwasan Observatory in Kyoto, Japan in May 1930. The Tau Herculids' average radiant was α=236°, δ=+41°. Due to orbital perturbations of the meteor streams by Jupiter, 2022 activity will have a radiant of R.A. = 13:56, Decl. = +28. The meteors are relatively slow moving making atmospheric entry at around.
On 31 May 1930 the comet passed about from Earth, on 9 June 1930 a meteor outburst with a zenithal hourly rate of around 100 was observed, and then the comet passed perihelion on 14 June 1930.
On 30–31 May 2022 there was a modest meteor shower generated by fragments from the 1995 break-up of the parent comet 73P. This required that fragments had been migrating ahead of the comet for the last 27 years. The parent comet has 69 known fragments and does not come to perihelion until 25 August 2022. On 30 May 2022 comet 73P/Schwassmann–Wachmann was 1.5 AU from the Sun and from Earth. The next notable appearances of the Tau Herculids are expected in 2033 and 2049.
