A rare celestial event, the auroras or ‘Northern Lights’, was visible across various parts of the globe for the another consecutive night on May 11, as per an AFP report. Caused by a massive solar storm, expected to last till May 12, these captivating displays already mesmerised viewers worldwide on May 10.
"I have the sensation of living through a historic night in France... It was really charged, with solar particles and emotions. Find good spots, away from the lights, with a clear view to the north!," Eric Lagadec, an astrophysicist at the Observatoire de Cote d'Azur, wrote on social media after the first night, AFP reported.
The commencement of the event unfolded shortly after 1600 GMT on Friday, as confirmed by the US-based National Oceanic and Atmospheric Administration's Space Weather Prediction Center (SWPC), the report said. This phenomenon resulted from the initial occurrence of several coronal mass ejections (CMEs), involving the expulsion of plasma and magnetic fields from the Sun.
The intensity of the solar storm escalated to an "extreme" geomagnetic storm, marking the first instance since the "Halloween Storms" in October 2003, which led to blackouts in Sweden and inflicted damage on power infrastructure in South Africa, as per the report.
Friday's storm attained level five geomagnetic conditions, the highest on the scale. Subsequently, Saturday witnessed conditions ranging from G3 to G5, with predictions indicating G4 or higher conditions persisting into Sunday, and the possibility of G3 conditions extending into Monday, it added.

Fortunately, despite initial concerns expressed by authorities, there have been no significant disruptions reported to power or communication networks during this period. The SWPC has only received “preliminary reports of power grid irregularities, degradation to high-frequency communications, GPS and possibly satellite navigation”, AFP said.
