Thiruvananthapuram Observatory Revisits 1859 Solar Flare Insights

### Quick Summary:
– Researchers at Kerala University have analysed past magnetic data from Thiruvananthapuram Astronomical Observatory relating to the 1859 Carrington Event,one of the most intense geomagnetic storms in history.
– Magnetic logs from Thiruvananthapuram were found to contain facts about an earlier solar flare on August 28, 1859. This precursor is believed to have destabilised Earth’s magnetic habitat and heightened the impact of the subsequent Carrington storm.
– Thiruvananthapuram’s records are unique thanks to thier fine-grained measurements taken at intervals of 2, 3, and 5 minutes, compared to records from Mumbai’s Colaba Observatory with only 5-minute intervals.
– The findings highlight Kerala’s contribution to advancing solar storm research using modern modelling tools applied to legacy datasets.- Scientists warn that if a similar geomagnetic event happens today, it could disrupt critical infrastructure such as power grids, navigation systems, broadband networks, and dialog channels-causing estimated economic damage exceeding $1 trillion.- The research is published in *Advances in Space Research*, a journal by COSPAR (Committee on Space Research).

### Indian Opinion Analysis:
This study underscores India’s historical contributions to global science through meticulous recording practices at observatories like Thiruvananthapuram. By digitising neglected datasets and applying advanced modelling techniques, researchers are not only enriching scientific understanding but also addressing contemporary concerns surrounding solar mega-storm preparedness.

the warnings about modern vulnerabilities-power grids and communications infrastructure-emphasise the necessity for updated disaster mitigation strategies. India’s reliance on digital technologies makes this research particularly relevant; proactive measures informed by past events can help shield critical systems from catastrophic disruptions. Furthermore, such studies reaffirm India’s role as a significant player in international space and environmental sciences.
