Abstract: Solar variability drives a wide range of geophysical phenomena, including space weather impacts far from the polar regions. This study investigates rare low-latitude auroral displays observed over Ladakh, India, during Solar Cycle 25, using both historical records and recent events from 2023-2025. Analysis links these sightings to X and M-class flare,associated coronal mass ejections, where high CME speeds and prolonged southward IMF Bz triggered severe geomagnetic storms (Dst down to -339 nT, Kp up to 8.7) and equatorward expansion of the auroral oval. Ground-based all-sky imaging, coupled with solar wind and geomagnetic data, reveals key mechanisms of Sun-Earth coupling during heightened solar activity. The findings highlight the importance of sustained solar monitoring, multi-instrument datasets, and international collaboration to improve understanding of solar magnetic variability and to assess its potential to produce significant space weather impacts at low-latitude, high-altitude sites such as Ladakh.
