Perseid meteor shower 2021
The Perseid meteor shower will be active from 17 July to 24 August, producing its peak rate of meteors around 12 August.
Over this period, there will be a chance of seeing Perseid meteors whenever the shower’s radiant point – in the constellation Perseus – is above the horizon, with the number of visible meteors increasing the higher the radiant point is in the sky.
The radiant point culminates (is highest in the sky) after dawn – at around 06:00 IST – and so the shower is likely produce its best displays shortly before dawn, when its radiant point is highest.
The shower is expected to reach peak activity at around 01:00 IST on 13 August 2021, and so the best displays might be seen before dawn on 13 August and after the radiant rises on 12 August.
At its peak, the shower is expected to produce a nominal rate of around 150 meteors per hour (ZHR).
