Friday 20 March marks the Spring Equinox for the Northern Hemisphere. The equinox, meaning 'Equal Night', marks the point in Earth's orbit around the Sun where the Sun appears to cross the equator (at 2:46pm UK time to be exact!) and sees the day split almost equally between day and night. From tomorrow onwards there will be more daylight hours than night-time ones up until the Summer Solstice on 21 June, the 'longest day'.

Happy Equinox everyone!

According to SpaceWeather.com a large Coronal Mass Ejection (CME - basically a very big solar flare) should impact Earth sometime on March 19th. If it behaves as predicted there could be quite a decent aurora display on offer.

At this time of year the chances of seeing the northern lights increase as well. For a few days around the spring and autumn equinoxes even the slightest impact of solar wind can cause a great deal of agitation of Earth's magnetic field and lead to some nice aurora displays. This is known as the "Russell-McPheron Effect" after the two scientist who first discovered this correlation back in 1973. If you want to read their scientific paper you can find it here - https://spaceweather.com/images2026/14mar26/Russell_JA078i001p00092.pdf

Please remember the aurora is a natural phenomena and a lot of factors have to line up for it to put in an appearance. The best advice as always is keep an eye on the aurora and weather forecast sites and go and take a look - you might not see anything if you do look but you will definitely not see anything if you don't!

The weather forecast around the Paisley area is not looking too great but if you have clear skies wherever you are and manage to get some photos of the aurora please do post your images here.

This photograph of the aurora was taken not too far from Coats Observatory at Bishopton, Renfrewshire in March 2024. Hopefully this coming display will be just as good if not better!

Thanks to everyone who came along to the stargazing session at Clyde Muirshiel Regional Park last night. We were treated to very clear skies and had great views through the telescope of Jupiter, the Orion Nebula, Andromeda Galaxy, Betelgeuse and Alcor & Mizar. No aurora unfortunately but we can't have everything all the time!

These photos were taken last night and highlight some of the objects we viewed and talked about over the course of the evening.

The final viewing night of this season on 23 March is sold out, but we will have more stargazing events later in the year. Full details will be posted here and on the Clyde Muirshiel Regional Park page once finalised.

Thanks again for your continued support of these events - it is greatly appreciated!

For everyone that is booked to come to tonight's stargazing session at Clyde Muirshiel Regional Park please note that it might take on a slightly different approach than previous sessions.

Clear skies are forecast and the telescope will be set up as usual. However, the aurora forecast is also looking reasonably good and the plan is to take a wander for about five minutes along the road towards the Barytes Mine if this forecast proves accurate. This area provides a much more open view to the north and therefore a better chance to see the aurora if it does put in an appearance. Remember, the aurora is a natural phenomenon and even if the stats look good it doesn't mean it will show, so no promises that we will see anything!

The road out to the mine is a bit rough so stout walking shoes are recommended. If you want to bring a torch please do so although there are some at the centre so don't worry if you don't have one. Do wrap up warm as we will be outside for the duration of the event as clear skies mean low temperatures at this time of year!

This photo was taken in September 2024 at Muirshiel at the place we plan to observe from, so here's hoping we get something similar tonight!

Thanks to everyone who came along to last night's stargazing session at Castle Semple. Unfortunately the weather was not on our side and the cloud and rain meant no telescope time. Hopefully we'll have clear skies next time!

There are only two nights left to run this season. February is completely sold out but there are a few tickets left for March. For more details and how to book please follow the link below.

Led by John Pressly – Science Curator at One Ren’s Paisley Museum – and Clyde Muirshiel’s Countryside Rangers, this series of outdoor events will explore some of the most mesmerising wonders of the night sky through a telescope. Expect to see the Moon, far-away galaxies, constellations and e...

We are finishing up today for the festive break, back again in early January. Can I take this opportunity once again to thank everyone for their continued support of Coats Observatory.

We should hopefully be reopening later in 2026 and once we know the details we will share them with everyone. I have managed to visit the building recently and, without giving anything away, it really does look fantastic and we are all looking forward to welcoming everyone back in the not too distant future.

The night sky doesn't take a break though and there are a few celestial treats to look forward to next year.

First off the aurora forecast for Christmas Eve and Christmas Day is pretty decent, so once the turkey and mince pies are finished it might be worth going out for a look if you have clear skies to the north. See the end of this post for links to the aurora forecasting pages.

On January 4th the Quandrantid meteor shower reaches its peak. This shower is active between 28 December and 12 January but reaches a peak on the evening of the 4th. It is quite a short-lived peak, lasting just a few hours, but can see rates up to 200 meteors per hour under ideal conditions. This coming peak the Moon will be full which will mean all but the brightest ones will be seen, but still worth taking in if weather conditions merit it. More info on the Quadrantids can be found here - https://www.rmg.co.uk/stories/space-astronomy/quadrantid-meteor-shower-when-where-see-it-uk

There are still a few spaces left for the February and March stargazing sessions at Muirshiel. For information and how to book tickets please see https://clydemuirshiel.co.uk/event/dark-sky-event-jupiter/ and https://clydemuirshiel.co.uk/event/dark-sky-event-moon-3/ respectively.

Later in the year there will be a partial solar eclipse, visible on 12th August. Whilst we will only see a partial eclipse from Paisley it will be total to viewers in western Iceland and northern Spain and Portugal. I've already booked a trip to Iceland so might be able to broadcast it live from a suitable location!

Have a great festive break and all the best for 2026!

- John

Today is the Winter Solstice, or the "shortest day". This is the point where the Earth's north pole is at its furthest tilt away from the Sun and we have the day with the shortest number of daylight hours. For those in the Southern Hemisphere the opposite is true and this is the "longest day" there.

The solstice actually occurs at 3:03pm our time. The nights will gradually get lighter again as the Sun sets a bit later each day. For more information on the solstice and why it occurs please visit https://www.rmg.co.uk/stories/time/when-winter-solstice-shortest-day

Happy Solstice everyone!

Thanks to everyone who came along to the final stargazing session of 2025 at Clyde Muirshiel Regional Park last night. Despite the fog at lower altitudes we were treated to very clear skies at the visitor centre. Through the telescope we saw Jupiter, Saturn, the Andromeda Galaxy, Orion Nebula and Betelgeuse. A few late Geminid meteors also showed up to add to a fantastic night of sky watching.

These photographs were taken shortly afterwards and really do show just how dark the skies are at Muirshiel.

The next viewing night is on January 26 and at Castle Semple. There are only a few tickets left! More details and how to book can be found at https://clydemuirshiel.co.uk/events/2026-01-26/

Thanks again for your continued support of these events, it is greatly appreciated.

The Geminid Meteor shower, active between 04 and 20 December, reaches a peak on the night of 13 into the early hours of 14 December.

The Geminids are the most prolific annual meteor shower, with peak rates which can reach up to 120 meteors per hour under ideal conditions of perfectly clear, light-pollution and Moon free skies.

Meteor showers take their name after the part of the sky that the meteors appear to radiate from, in this case the constellation of Gemini the Twins. This constellation is fairly easy to spot as it lies just to the left of Orion, recognisable by the three stars in a row marking his belt. The 'twin stars' of Castor and Pollux, the two brightest in Gemini, sit one above the other.

The source of the Geminids is rather unusual in that it is not a comet but an asteroid called 3200 Phaethon. Geminids tend to be quite bright and can be a mix of colours, including yellow, green, red and blue, with these colours coming from he presence of small amounts of metals such as sodium and calcium.

Meteors can appear anywhere in the sky. To check if its a Geminid follow the tail back and if it points towards Gemini then it will have been a Geminid meteor.

The best way to observe any meteor shower is to sit back in a comfy chair (a deck chair works best), wrap up warm and keep your eye on the sky. Your eyes are the best tools to observe the shower as binoculars or a telescope will reduce your field of view too much. The darker the skies the more meteors will be visible, so if you can get away from street lights and other artificial light sources.

At the moment the weather forecast for the Paisley area is not looking too good, but if you do have clear skies wherever you are you should definitely try to catch the show!

The image shows a Geminid meteor passing by Orion. If anyone manages to photograph a meteor please do post it here.

Spaceweather.com are predicting a large geomagnetic storm beginning on 09 December. This will be the result of an incoming Coronal Mass Ejection (CME) which looks like it will hit Earth at some point on Tuesday.

This CME has come as a result of a very powerful eruption on the Sun and, if it behaves as hoped, should spark some very nice displays of the Northern Lights.

At the moment the weather around the Paisley area is not looking too good for aurora watching with thick cloud, heavy rain and high winds forecast (it is winter after all!). The Moon will also be up around 9:30pm which will add to the overall brightness of the sky and will wash out the aurora unless it it very strong. However, if you do have clear skies where you are it will be worth taking a look just in case - you might not see anything but if you don't look you definitely won't see anything!

As ever the best advice is keep an eye on the various aurora and weather forecast pages. If anyone does capture any photographs of the aurora please do post them. The image was taken at Lunderston Bay on the Clyde Coast in May 2024. That night the aurora was so strong that you had to look south to see it! If the incoming solar wind acts as forecast this storm could be just as big.

Good luck and stay safe if out aurora hunting.

spaceweather.com is reporting an incoming "Cannibal CME" - basically two coronal mass ejections which have merged - which is due to impact Earth today. If it behaves as it hopefully will we could be in for a pretty extreme geomagnetic storm and the possibility of aurora displays overhead.

Unfortunately the weather forecast is not looking too great and the whole of the UK looks to be blanketed in cloud, at least until midnight, although there may be clear patches dotted about. The east coast looks a bit better after that, especially around the North Berwick area, so if you are lucky enough to be there you may be in for quite a show!

If - and there is always an 'if' when it comes to trying to predict if conditions mean the aurora will appear - these conditions are as forecast the storm could last a couple of days, so well worth tracking down some clear night skies if you can as we could be in for quite a show.

As ever the advice is keep your eye on the usual aurora and weather forecast sites and if you do have clear skies go out and take a look.

The photograph is from the large solar storm in May 2024 and was taken at Lunderston Bay near Inverkip on the Clyde Coast. The storm was so big that the aurora was actually to the south rather than the usual north! If the forecast is correct this incoming storm could be just as big.

Good luck if you are out aurora hunting and if anyone photographs the northern lights tonight please do post your images below.

Many thanks to everyone who came along to the stargazing event at Clyde Muirshiel Regional Park. Despite the forecast of complete cloud cover we did get a fairly clear sky and everyone saw the simply stunning Saturn through the telescope!

The next event is on December 15 also at the Muirshiel Visitor Centre. There are only a few tickets left for this event so if you wish to come along please visit https://clydemuirshiel.co.uk/event/dark-sky-event-jupiter-saturn/ to secure your place.
