We analysed visual observation data of the Tau Herculids collected between2022 May 28 and June 1. The population index for the entire sample is 2.4. Forthe pre-peak period we find r=2.57+-0.23, the peak period yields r=2.38+-0.06.The ZHR maximum of the 1995 ejecta from comet Schwassmann-Wachmann3 (SW3) isfound at 69.450 deg solar longitude (May 31, 05h04mUT, +-5min) with aZHR=55+-7, corresponding to a spatial number density ND of approx. 380meteoroids larger than 10mg in a cube with 1000km edge length. An earliermaximum occurred at 69.207 deg solar longitude (centred May 30, 23h UT) with aZHR=18+-3 and is tentatively associated with SW3-ejecta from 1892. Effects ofthe radiant shift due to the large zenith attraction of about 10 deg for theradiant close to the horizon are discussed.
