A partial solar eclipse will be visible across Sussex tomorrow (Wednesday, August 12).

The event will be the biggest of its kind since 1999 and won’t occur on a similar scale until 2081.

The Home Office have warned onlookers to wear specialist eclipse eyewear – not just sunglasses.

In West Sussex, the eclipse begins at 6.18pm, reaching maximum coverage at 7.14pm and ending at 8.07pm.

Horsham District Council and Horsham Museum & Art Gallery will host an ‘Eclipse-nic in the Park’ in the Human Nature Garden in Horsham Park between 5pm and 7.30pm tomorrow evening.

A Horsham District Council spokesperson said: “An informal picnic in the Human Nature Garden, Horsham Park to experience the partial solar eclipse this summer. Astrophotographer Claire Bradshaw, and members of Horsham Astronomy Group will be on hand to guide you through what is happening in the sky. As it is never safe to look directly at the sun, attendees are encouraged to BYOC (bring your own colander) as a simple alternative to a pin hole projector.

“Please note that this is an informal gathering to enjoy the eclipse and that there will be no refreshments available at the event so those attending should bring their own picnic.

“The event is weather dependent and if there is rain or cloud cover then the Eclipse-nic will not take place. Please check the museum website in the lead up to the event for full details.”

Southwater Sports Club will be hosting a viewing event from 7pm, while The Crown in Capel is inviting residents to make use of their beer garden to watch the eclipse from 6pm.

There will also be an eclipse viewing party in Knowle Park, Cranleigh, which kicks off at 6pm.
