An astronomical double bill awaits on Wednesday evening, with a partial solar eclipse giving way to a meteor display.

The partial eclipse commences at 6.16pm when the Moon positions itself between our planet and the Sun, creating a shadow across certain regions. While the total blackout zone passes elsewhere, South Wales experiences substantial coverage, missing out on the moment when the Sun sits fully obscured. Our area will witness 93.2 percent of the solar disc blocked from view, compared to 90.7 percent in Edinburgh, 91.4 percent in London, and 93.1 percent in Belfast.

At 6.16pm the initial contact occurs as the lunar limb meets the solar limb. Peak obscuration, when the greatest portion of the Sun disappears, takes place at 7.13pm, leaving a significant portion of the solar disc concealed. The event concludes at 8.07pm once the Moon has moved sufficiently away.

Viewers should employ certified solar viewing glasses for safe observation, though binoculars or telescopes must be avoided as concentrated solar intensity will inflict severe retinal harm. Those preferring to watch virtually can access live streams through various platforms, including www.timeanddate.com.

Following this, the Perseid meteor shower reaches its most active phase as Earth traverses the trail left behind by Comet 109/Swift-Tuttle. From approximately 11pm, tiny particles roughly the size of grains of sand will hurtle into our atmosphere at roughly 37 miles per second, incandescencing briefly to create luminous streaks across the heavens. Anticipate somewhere between 80 and 100 meteors hourly under optimal conditions. The optimal viewing direction lies towards the north-east.
