SolarSteph 🌞

Excited to announce that after popular demand I have now created a space weather dashboard on my website, you can access it here: forecast.stephyardley.com 🌞 🛰️ Suggestions welcome!

Updated my space weather dashboard 🌞 🌎️ this afternoon so it now includes coronagraph data from CCOR-2 and the auroral oval forecast from the Met Office! 👉️ forecast.stephyardley.com

Today's aurora and space weather 3-day forecast! 🌌 The 21 Oct CME never arrived, and slow solar wind means quiet conditions through Thursday 🌬️ Biggest flare: C2.9 🌞💥 Aurora💚: unlikely in the UK over the next few days 👀 👉️ forecast.stephyardley.com #spaceweather #aurora

The Sun over the last 24 hours! 🌞 Quiet again today but what is really interesting is the returning coronal hole (dark feature) in the eastern hemisphere (right side of the Sun). Since it was visible in the previous rotation (27 days ago) it has split possibly due to active region emergence

Solar wind connection dashboard ☀️🌍 Slow wind (~340 km/s), but the field (~8 nT) is pointing south and Kp is 2. The model puts Earth's connection at the Sun's western edge but confidence is low. A big coronal hole (CH07+) is now facing Earth, which is worth watching in the coming days!

Today's aurora and space weather 3-day forecast! 🌌 The 21 Oct CME hasn't arrived yet; 🌞💨🌎️ HUXt gives a 40% chance of a weak glancing blow by this evening 🌬️ Sun: several C flares, biggest C2.0 🌞💥 Aurora💚: UK unlikely unless the CME boosts it 👀 #spaceweather #aurora

The Sun over the last 24 hours! 🌞 The most interesting feature on the Sun right now is the coronal hole (dark feature) that's just rotated around onto the solar disk from the east limb (left edge). This could lead to fast solar wind speeds at Earth & geomagnetic storm conditions later in the week! 🌬️

Today's aurora and space weather 3-day forecast! 🌌 Coronal hole wind 🌬️ & a possible glancing CME 🌞💨🌎️ may bring active spells today, chance of G1 storm Quiet Sun: biggest flare B5.7💥, sunspots down to 51 🌞 Aurora💚: chance in N. Scotland tonight 👀 #spaceweather #aurora

Today's aurora and space weather 3-day forecast! 🌌 A weak solar wind boost may arrive today, 🌬️ with a possible glancing CME Sunday 🌞💨 🌎️ Biggest flare: C1.3💥 Aurora💚: slight chance in N. Scotland tonight and Sunday night, if Storm Boelo's cloud clears 👀 #spaceweather #aurora

Solar wind connection dashboard ☀️🌍 Solar wind has settled to around moderate speeds of 420 km/s (density ~5 per cm³ and ~6 nT field). Kp is low. Earth is still connected at the Sun's western edge, where coronal hole CH04+ is rotating out of view.

Today's aurora and space weather 3-day forecast! 🌌 Quiet today, but fast wind from coronal hole CH06 (centre of the Sun) is due Saturday, with a possible glancing CME Sunday 🌬️ Biggest flare: C3.4 🌞 Aurora: chance in N. Scotland Sat night and Sunday if clear 👀 #spaceweather #aurora

The Sun over the last 24 hours! 🌞 Mainly quiet but if you look closely there is a very small but fast filament eruption near the West (right) limb that occurred early this morning (not Earth-directed). 🌞💨🌎️

My solar wind connection dashboard ☀️🌍 The faster wind is easing: ~440 km/s, down from ~525 yesterday. Density is ~4 per cm³ and the field ~6 nT, still pointing south. Kp reached 4.7 last night, just below storm level. Earth is still connected to the Sun's west limb.

Today's aurora and space weather 3-day forecast! 🌌 Fading fast winds could still bring G1 storms today 🌬️ Calmer Friday, more fast wind Saturday, and a possible glancing CME Sunday. Biggest flare: C3.6 🌞 Aurora: chance in N. Scotland today and again this weekend if clear 👀

Earth Solar Wind Connectivity Dashboard! ☀️🌍 Earth is now connected in CH04+, the same coronal hole as before. That fits the faster wind now arriving (~500 km/s, up from ~380 this morning). Model confidence is high! 😃

Today's aurora and space weather 3-day forecast! 🌌 Fast wind from coronal hole CH04 brings a chance of minor (G1) storms today 🌬️ Settling Thursday, quiet Friday. Solar activity is low, with a 25% chance of M-class flares 🌞 Aurora: slim chance in N. Scotland tonight if clear 👀 #spaceweather #aurora

The Sun over the last 24 hours! 🌞 Mostly quiet, we can see the coronal hole (dark patches) rotating across the Sun and some filament activity close to the coronal hole in the west (right) whose moderately fast (~450 km/s) wind stream arrived at Earth yesterday 🌬️ 🌎️

We are currently being buffeted by fast wind from a coronal hole.🌬️ Minor (G1) geomagnetic storm conditions likely with Aurora in North Scotland 🌌 #aurora #spaceweathet

I've developed a new dashboard based on my solar wind connection research ☀️🌍 It tells us what is the source of the solar wind currently hitting Earth. We're most likely linked to coronal hole CH04+ (a dark patch on the Sun), and solar wind from the CH is starting to arrive. Aurora possible! 🌌

Today's aurora and space weather 3-day forecast! 🌌 Fast solar wind from coronal hole (CH04) arrives today 🌬️ Chance of minor (G1) storms, unsettled into Wednesday. No significant flaring recently but there is a 30% chance of M-class flares 🌞 Aurora: possible in northern Scotland tonight 👀

The Sun over the last 24 hours! 🌞 A quiet day with no Earth-directed CMEs. The dark region on the Sun currently facing Earth is a coronal hole, where magnetic fields are open and it lets fast wind easily stream towards us 🌬️

Today's aurora and space weather 3-day forecast! 🌌 Fast wind from a coronal hole arrives late today or Tuesday 🌬️ bringing a chance of minor (G1) storms. On the Sun: 4 active regions, and AR4551 fired an M1.6 flare this morning ☀️💥 Aurora: potentially northern Scotland 👀

AR4551 produced an M1.6 flare in the last hour or so, peaking around 09:10 UTC. Its second M-class flare in four days, even though it's shrinking 🌞💥 SDO/AIA 131 Å shows plasma at ~10 million degrees. Too early to say if there's a CME. 🌞💨

The Sun over the last 24 hours! 🌞 We can see the coronal hole (dark feature) rotating across the solar disk that will lead to a high-speed solar wind stream arriving at Earth shortly. To the west (right) of the coronal hole we can see a filament becoming unstable, lifting off and erupting 🌞💨

Today's aurora and space weather 3-day forecast! 🌌 Quiet until a new coronal hole stream arrives, 🌬️ most likely late Monday/Tuesday bringing a chance of minor (G1) storms. 2 coronal holes and 3 active regions on the Sun 🌞 Aurora: potentially northern Scotland 👀 #aurora #spaceweather

Today's aurora and space weather 3-day forecast! 🌌 AR4551 fired an M1 flare yesterday afternoon ☀️ but has since started shrinking. Quiet this weekend, but a new coronal hole stream may bring active spells from Monday 🌬️ Aurora unlikely across the UK #aurora #spaceweather

This is the region to watch! 👀 Although Active region 4551 hasn't done much so far, it is still emerging. Not much flaring as its only emerging slowly, but hopefully some eruptions in the decay phase if the magnetic fields become more sheared and build up some energy? 🤞 🌞 💨 🛰️ 🌎️

Today's aurora and space weather 3-day forecast! 🌌 Quiet into the weekend as the coronal hole wind fades 🌬️ The complex region AR4551, now disk centre, is the one to watch for flares 🌞💥 Fast solar wind could arrive late Monday 🌬️ #aurora #spaceweather

Today's aurora and space weather 3-day forecast! 🌌 Quiet conditions as the high-speed coronal hole wind eases 🌬️ The complex βγδ region AR4551 in the south-east is the one to watch for flaring. ☀️ Aurora unlikely to be seen in the UK. #aurora #spaceweather

There was a huge filament eruption on the Sun today!

According to the HUXt model, the CME from Monday's filament eruption should arrive just after midday on Wed 14 Oct, giving Earth a glancing blow. Remember that there are uncertainties in the timing of these models. 🌞 💨 🛰️ 🌎️ #spaceweather #aurora

Today’s aurora and space weather 3-day forecast! 🌌 Minor G1 storms are still likely due to the influence of a coronal hole high-speed stream. 🌞🌬️ A filament eruption is also on the way and may glance Earth on Wed 14th October. 🌞 💨 🛰️ 🌎️ #SpaceWeather #Aurora

Today's 3-day space weather and aurora forecast! 🌌 G1 (minor) storm conditions possible due to glancing blows from coronal mass ejections and coronal hole high-speed streams. Aurora possible visible mainly in Scotland. 🌞 💨 🛰️ 🌎️

There have been two filament eruptions on the Sun in the last 24 hrs, one was triggered by the other. We call these sympathetic eruptions. One definitely produced a CME which will provide a glancing blow at best, will have to wait and see about the second. 🌞 💨 🌎️ 🛰️

After last night's aurora, here's the space weather forecast for the next 3 days. G1–G2 (minor–moderate) storms possible today and Monday. Aurora most likely in Scotland, possibly Northern England. There are 2 coronal holes and 6 active regions on the Sun right now 🌞 #aurora #spaceweather

Aurora visible in Newcastle go outside now!!!

Looks like a CME arrival! 🌞💨🌍

Aurora forecast this weekend! 🌌 We have two possible CMEs arriving (glancing blows) and a high-speed stream from a coronal hole, which means the aurora may be enhanced between 10-13 Oct. Sightings mainly in northern Scotland with clear skies. G1 (minor) storm conditions, maybe G2 (moderate) 🌞 💨 🛰️ 🌎️

As expected, the Prime Minister's promise to sort out the mess of funding for Jodrell actually meant nothing - it seems the government would like it to be some sort of heritage theme park when you can go and see where we used to do science. 🔭

Aurora update 🌌 Here's the latest eruption from the Sun 👇 3 CMEs (6, 7 & 8 Oct) 🌞 💨 💨 💨 🛰️ 🌎️ could reach Earth 9-11 Oct. The Met Office forecast has a chance of G2 storms and a slight chance of G3, so aurora is possible over Scotland, and possible northern England. Timing is very uncertain, so 🤞

🚨 Aurora watch 🌌 A CME that left the Sun on 6 Oct is due early Fri 9 Oct. G1 storm expected, chance of G2, so aurora possible across northern UK at the peak. A glancing blow from a 7 Oct CME could add more chances Sat/Sun night. 🤞 for clear skies! (Auroral forecast shown from Met Office)

Wow impressive images of the Earth’s aurora taken by the recently launched SMILE mission 🤩🛰️

Calling all #eclipse and geeky data science lovers! Check out this fantastic timelapse that displays the changing temperature relative to the %age of sunlight. I'm sure you'll all agree with me that this is <chef's kiss> marvellous! Bravo to Wayne!

Well I would share my eclipse pictures but I don’t have any, unless you want pictures of cloud?! 🤣🌞🌚
