The biggest meteor shower of October is here！October 21 marks the peak of the Orionid meteor shower. Under conditions of no light pollution and clear weather, an estimated 20 meteors per hour can be seen. In addition to the meteor shower, it's also the best time recently to observe Uranus. According to the Central Weather Bureau, the northern and northeastern regions, which face the wind, will experience cloudy and rainy weather over the weekend, making them less suitable for observation. The central and southern regions will have mostly cloudy to clear skies, while Hualien and Taitung will be partly cloudy—offering better viewing conditions.

The Orionid meteor shower is a medium-sized annual meteor shower that occurs regularly, typically active between October 2 and November 7. This year, its peak falls on October 21, which is not only a Saturday but also coincides with the waxing crescent moon on the second day of the lunar calendar, meaning it is barely affected by moonlight, offering excellent visibility.

Orion rises in the east around 22:00–23:00 in the evening. The period from after 22:00 on October 20 to before dawn on October 22 is ideal for viewing. The peak of this meteor shower usually lasts several days, and the shower can be observed for about half a month from mid-October to the end of the month.

Uranus reaches opposition on October 20, meaning that the Sun and Uranus are on opposite sides of the Earth. At this time, it is almost at its closest to Earth, brightest, and largest in apparent diameter for the year, and visible all night.
