Meteorological day 2021 – Orionidy
They will come after this meteor swarm Orionidy. Twice a year our planet encounters a meteor shower coming from Halley's Comet. It's the first time in May, when the swarm eta-Aquarid is active. In the second half of October, the maximum Orionides occur.
The swarm is active from October 2 to November 7 2021, whereas the maximum is expected on October 20 in the morning. The fibrous structure of the swarm causes the maximum not to be very sharp, or it is possible to speak of several maxima, which last for several days. ZHR is estimated at 20 – 25. The radiant swarm is located in the northeastern part of the constellation Orion, 5 degrees west of a second-sized star called Alhena (or Gamma Geminorum).
Orionids are the second fastest swarm after the Leonids, they enter the atmosphere at speed 66 km/s. There are quite a few small particles in the swarm. Like other fast meteors, they leave traces of visible seconds to minutes in the sky. When looking at the radiant, the observer sees short meteors, while focusing on a quarter of the sky from that point, registers long and very fast meteors.
