Not an aurora???
Many throughout the world were able to experience another great evening of auroras on New Year’s Day 2025. However, there’s a catch, some actually saw what are known as SAR arcs. These were first discovered in 1956. Researchers weren’t sure what they were and gave them the misleading name, Stable Auroral Red arcs.

A G3 (Strong) geomagnetic storm watch is set for December 31! 
This is due to a coronal mass ejection (CME) from the Sun. Stay informed and check for updates!

Sonnensturm im Mai 2024 verursachte eine physikalisch schwer erklärbare Aurora über Japan.
SpringerOpenSpatial structures of blue low-latitude aurora observed from Japan during the extreme geomagnetic storm of May 2024 - Earth, Planets and SpaceOn May 11, 2024, an extreme G5-class geomagnetic storm triggered a spectacular and unusual display of colorful auroras in mid- to low-latitude regions all over the world. In Japan, auroras were seen not only from Hokkaido, the northernmost island, but also from the northern and central parts of Honshu, the main island. The widespread availability of commercial digital cameras among the public led to a flooding of high-resolution auroral images on social media. This study reports on the appearance of a blue-dominant aurora during a storm-time substorm on this day and its magnetic field-aligned and longitudinal structures captured by citizen scientists. Observations from two photographers at different locations revealed that the aurora was located at approximately 40 degrees magnetic latitude and magnetic local time (MLT) of 23 h, spanned about 1200 km (1-h MLT) in the longitudinal direction with three separated structures, and ranged in altitude from 400 km to at least 900 km. Simultaneous photometric measurements suggested that this blue-dominant aurora likely included emissions at 427.8 nm. While previous studies have noted the existence of emissions at 427.8 nm in low-latitude auroras, this is the first time that a blue-dominant low-latitude aurora has been spatially identified and shown to have longitudinal and field-aligned structures. Additionally, previous studies suggested that blue emissions in low-latitude auroras are produced by energetic neutral atoms from the ring current. However, identifying longitudinal and field-aligned structures in this study may need an alternative explanation. Graphical Abstract

I took over 4,000 photos of the #AuroraBorealis last night so it's hard to pick favourites, but here are 4 that stood out. Taken from #Oxfordshire UK (52'N) with 2 Canon 1100Ds with 10mm & 18mm lenses #NorthernLights #Aurora #MidLatitudeAurora #GeomagneticStorm
The #AuroraBorealis put on a spectacular show last night across the whole UK and into mainland Europe! We had #CoronalAurora overhead again, red arc in the southern sky, green along the southern horizon & the northern sky went bonkers!

Another #XFlare / Severe #GeomagneticStorm Watch

"A moderate (S2) to Strong (S3) radiation storm remains in progress following the energetic X-Flare produced by #AR3848.
"A severe (G4) geomagnetic storm watch was officially added beginning tomorrow when the fast moving CME associated with the flare event is expected to sweep past Earth. While there are no guarantees, a repeat of the geomagnetic storm and aurora event back in May could be on the horizon.
"Oh... and an impulsive X1.4 solar flare was observed around departing AR 3842 at 15:47 UTC (Oct 9)."
