⚠️ Cannibal CME Expected Soon – Aurora Watch for Ireland 🌌

A Cannibal CME (Coronal Mass Ejection) is expected to impact Earth soon after three CMEs erupted from the Sun on 2 June, with the fastest eruption catching up to the earlier ones and combining into a stronger event before arrival.

🛰️ Latest Update
• The 1st CME was detected by the ACE spacecraft at 04:31 UTC (05:31 Irish time) and swept past Earth at 05:11 UTC (06:11 Irish time).
• Additional CME energy is expected to follow as the event evolves.

🌍 Potential Impacts
• G3 (Strong) geomagnetic storm conditions remain possible, with a chance of briefly reaching G4 levels if the storm becomes more Earth-directed.
• Aurora visibility across Ireland may improve tonight, especially if skies clear and storm intensity strengthens. If a strong enough storm develops the Aurora could still be visible but will not be visible to the eye like you would see it during the darker winter, Autumn and spring nights.

🌧️ Viewing Conditions Tonight
Unfortunately, weather conditions may limit viewing:
• Widespread rain, heavy in some areas (especially the south)
• Mist and hill fog reducing visibility
• Breezy to gusty winds, strongest near coasts

👀 Best Advice
Keep an eye on real-time aurora alerts and local sky conditions. If breaks in cloud develop, especially across northern and western areas, there may still be opportunities to catch the Northern Lights.

What Noctilucent clouds look like

Noctilucent cloud season starts late May and ends during the month of August always look northwards

Observing noctilucent clouds is easy and, best of all, completely free. You don’t need any expensive telescopes, binoculars or cameras. Just a pair of eyes will be fine.

Having said that, a pair of binoculars will allow you to see fascinating detail and structure within an NLC display that is invisible to the naked eye.

You don’t need to be under a pitch black sky to see them, as a good display will be so bright that it will be visible from your back garden or even your bedroom window, as long as you’re facing north.

Noctilucent clouds typically begin to show themselves around midnight, when the summer sky is as dark as it’s going to get.
