Astrometric observations near the maximun approach of the Potencially Hazardous Asteroid (66391) 1999 KW4

Our team decided to collaborate with the campaign to observe the maximum approach of the PHA (66391) 1999 KW4, organized by the International Asteroid Warning Network (IAWN). The observations were made from CIEASEST, in the Universidad Nacional San Luis Gonzaga de Ica, Peru (Long. 75 44 12.5 W, Lat. ...

SIMONe Peru: deployment and operations

SIMONe Peru is a modern multistatic specular meteor radar which allows measuring winds in the mesosphere and lower thermosphere (MLT) between 70 and 110 km in altitude. Its main objective is to study the atmospheric dynamic in this region. Moreover, the system provides a higher number of detections ...

Exploring the correlation between ionospheric scintillation and GNSS positioning error near the magnetic equator using machine learning techniques

Ionospheric scintillations are a common phenomenon in the equatorial ionosphere. This phenomenon directly affects the position estimated by GNSS receivers degrading the quality of the radio signals; however, the quantification of the positioning error contributed by the ionosphere over the Peruvian ...

Storm-time equatorial thermospheric dynamics and electrodynamics

It presents the first comprehensive study of the equatorial thermospheric dynamics and ionospheric electrodynamics over Peru following enhanced energy depositions into the high-latitude ionosphere during geomagnetic storms. We used extensive observations of ionospheric plasma drifts and of night-time ...

OAUNI astronomical photometry: stellar variability of FO Aqr on 2016 low state

This work reports a photometric monitoring of the intermediate polar cataclysmic variable star FO Aqr. This is part of the ongoing OAUNI stellar variability program. Around 1200 individual measurements (or ∼ 9 hrs of observations) were gathered distributed in five nights. The observation epoch was ...
