Ionospheric storm-time effects in the Peruvian sector

Solar cycle 25 began in December 2019, and solar activity continuously increases until it reaches the predicted maximum near 2025. As a result of this increased solar activity, more intense solar flares, and coronal mass ejections events are detected more frequently. Solar flares are large eruptions of electromagnetic radiation from the Sun lasting from minutes to hours, while coronal mass ejections that hit the Earth generate geomagnetic storms. Therefore the monitoring of these events is relevant for space weather specification. In this work, we report X-class solar flare and geomagnetic storm effects on the Peruvian ionosphere during the ascending phase of the current solar cycle. We used measurements from ground-based instruments located at the Jicamarca Radio Observatory, such as the ionospheric radar, magnetometer and ionosonde, to identify perturbations produced in the magnetic field, plasma drift, and ionograms signatures. In addition, these results are compared with the variations of solar flux (F10.7) and geomagnetic indices (Dst and Kp).
