Why don’t you all enjoy the long autumn nights on the weekend?
I’m curious about the weather tonight
Tonight and early tomorrow morning, the atmospheric pressure will be in a winter-like pattern, and clouds will spread around areas along the Sea of Japan, such as northern Japan and Hokuriku, due to the influence of cold air. It seems difficult to observe meteors because of the rain that comes and goes.
On the other hand, areas on the Pacific side tend to have clear skies, and there are many places where you can enjoy observing meteors. Even in the Kanto region, where there are many clouds during the day, it seems that there are many places that become clearer as the night progresses.
At night, temperatures are expected to be low for this time of year, and strong northerly winds are expected. If you stay still outdoors, your body will get colder than you might imagine. If you plan on observing, don’t forget to protect yourself from the cold.

What kind of meteor shower is the Orionid meteor shower?
Around 23:00 on Saturday, October 21st Eastern sky (Tokyo)
The Orionid meteor shower is a meteor shower that reaches its peak activity around October 21st every year. The parent object is Halley’s Comet, which is the same as the Eta Aquarids meteor shower, which peaks during Golden Week.Meteors begin to flow around 9pm, when the radiant point
rises in the sky, but late at night and early morning are the best times to observe as the radiant point rises higher.
*Radiant point: A point on the celestial sphere from which shooting stars (meteoroids) appear to fly out.
This year, the moon will set by the time the radiant point rises, so there is no need to worry about moonlight during observation hours. According to AstroArts, you can expect to see 5 to 10 meteors per hour during the peak hours when the area is dark and the view is good.

Additionally, since the meteor shower peaks on a gentle slope, there are opportunities to observe it on several days other than the peak day. If tonight’s observation is difficult, please look forward to meteor observation during the long autumn nights from tomorrow onwards.
