PARTIAL SOLAR ECLIPSE TOMORROW MORNING! - 25/10/2022 🌞🌑

On the morning of the 25th of October 2022 during this months new moon phase, we will be treated to views of an amazing partial solar eclipse.

Following our previous heads up post for this solar eclipse, we would like to give you some more information. If you would like more info, please read on.

SAFE SOLAR VIEWING!

Never look directly at the Sun with your eyes and never use binoculars or a telescope without appropriate solar filters to look at the Sun. Doing so may result in permanent irreversible eye damage. Never image the sun directly without the correct equipment, as this may damage your camera.

There are a few ways you can safely witness a solar eclipse:

• You can buy solar safety glasses that will allow you to view solar eclipses with your eyes.

• You can create your own pinhole camera that will project an image of the sun onto a flat surface. To do this make a small hole in a piece of card, hold this card facing the sun. Then take a second piece of card (ideally white in colour) and place it behind the other card. An image of the sun will be projected onto the second card (move it further or closer away from the pinhole to try to sharpen the image.

• A household kitchen colander makes for a great pinhole camera too, projecting lots of small images onto your card.

• You can also make a pinhole projection box that will give you a better view by projecting the Sun’s image onto a surface in a dark container (such as a cardboard box). This will stop glare from the bright surrounding are and give better contrast. See the picture below for an idea of what a pinhole projection box looks like.

• You can also use a pair of binoculars or a telescope to project the Sun’s image onto a surface, much like a pinhole camera. This method will project a sharper and larger image. Point your binoculars or telescope towards the sun (DON’T LOOK THROUGH THEM, just roughly aim them at the sun) and place a piece of card behind the eyepiece. Just like a pinhole camera an image of the Sun will be projected onto this card. If you use this technique it is best to use a piece of equipment with simple construction, the heat absorbed from pointing at the sun can cause damage to complicated fixtures, coatings and glues within binoculars or a telescope.

• If you own a pair of binoculars or a telescope you can buy specialised solar filters to attach to your equipment to safely view the eclipse. Make sure the filters are well fitted following all instructions.

• You can also watch live streams of the Solar Eclipse from home.

WHY DO SOLAR ECLIPSES HAPPEN?

Solar eclipses happen when the Moon travels in between the Earth and our closest star, the Sun, partially or totally obscuring the Sun's visible surface in the sky. The eclipse on the 25th will be a partial solar eclipse with up to 35% of the Sun being obscured for those of us in the UK.

WHEN AND WHERE WILL THE PARTIAL SOLAR ECLIPSE HAPPEN?

The partial solar eclipse will begin at around 10:05 on the morning of the 25th of October. Maximum eclipse (when the sun will be most obscured) will be around 11:00, and the eclipse will end at around 11:50. All times are given in BST. Times vary slightly across the UK, however only by several minutes, so do make sure you're ready and waiting a few minutes before 10:00 BST if you can.

You don’t have to be anywhere special to view this solar eclipse however, those in the North-East of the UK will see a larger amount of the Sun being obscured (up to 35%) compared to those in the South-West.

VIEWING TIPS

• Special equipment is required to view this eclipse safely. Make sure to use solar glasses or a pinhole camera or watch the eclipse via the internet.

• You may want to practice making a pinhole camera and testing it with a bright lamp before the eclipse itself.

• Do not look through the pinhole in a pinhole projector.

• Always keep your back to the sun when using projection methods.

• If using binoculars or a telescope projector, only use it for a few minutes at a time. The heat absorbed while pointing at the sun may damage your equipment and even potentially create a flammable hot spot on the card.

• Never look at the sun directly with your eyes or with unfiltered equipment!

• Remember to follow all these safety rules and you will have a completely safe, great time observing the eclipse.

• Enjoy this rare and spectacular occasion!

We will be making sure to be out to try and view, and possibly capture this moment with our solar telescope. We can’t wait to witness this amazing solar eclipse and wish you all good luck, if you head out too!

Clear Skies 💖
