#aurora looks like we might get some aurora tonight, the index is climbing slowly and clear skies here in JO01ij :)

currently mid 80's if it gets over 100-120 you can normally see the aurora with phone camera here, and if over 180-200 visible to naked eye

January skies over Fairbanks, Alaska.
We're only a couple weeks away from having real darkness again — and while I'm not quite ready to let go of summer, I'm definitely looking forward to chasing aurora this season. I took a break from it last winter, but it’s time to get back out there.

Fireball Above Iceland
by Babak Tafreshi
print.babaktafreshi.com/talks-

"On 2023 September 13, near the northern most point of Iceland, the night sky exploded with the northern lights and a spectacular fireball, above the Arctic Henge monument. I was about to move our group to another spot when this tennis-ball sized space rock entered the earth atmosphere and burned at an altitude of 60-90 km above us, becoming as bright as the full moon for a moment. Such meteors are very rare to witness. Even for a frequent observer like me it took three decades to finally record one in video!
I was on my biannual Aurora PhotoTour. My Icelandic colleague ‪Stjornu Saevar‬ appears near the clip’s end, on a phone interview with the local media about the meteor."

Fireball over Iceland

Explanation:
On September 12, from a location just south of the Arctic Circle, stones of Iceland's modern Arctic Henge point skyward in this startling scene. Entertaining an intrepid group of aurora hunters during a geomagnetic storm, alluring northern lights dance across the darkened sky when a stunning fireball meteor explodes. Awestruck, the camera-equipped skygazers captured video and still images of the boreal bolide, at its peak about as bright as a full moon. Though quickly fading from view, the fireball left a lingering visible trail or persistent train. The wraith-like trail was seen for minutes wafting in the upper atmosphere at altitudes of 60 to 90 kilometers along with the auroral glow.

Aurora and Unusual Clouds Over Iceland

Explanation:
What's happening in the sky? On this cold winter night in Iceland, quite a lot. First, in the foreground, lies the largest glacier in Iceland: Vatnajokull. On the far left, bright green auroras appear to emanate from the glacier as if it was a volcano. Aurora light is reflected by the foreground lake Jökulsárlón. On the far right is a long and unusual lenticular cloud tinged with green light emitted from another aurora well behind it. Just above this lenticular cloud are unusual iridescent lenticular clouds displaying a broad spectral range of colors. Far beyond the lenticular is the setting Moon, while far beyond even the Moon are setting stars. The above image was captured in late March of 2012.
