The National Space Weather Laboratory (LANCE) in Mexico has a network of instruments  (magnetometers, ionosonde, Callisto antenna, MEXART radio telescope and cosmic ray detector) that are used to monitor the space weather in Mexican territory. The network of instruments is used to study the condition of the interplanetary medium, the geomagnetic field and the ionosphere through its own data. Since 2018, the network of instruments have observed different events generated by interplanetary structures. In particular, the severe geomagnetic storm of last May 10 has been recorded. In this work we present the observations registered by each instrument such as solar radio burst, geomagnetic variations, ionospheric disturbances, energetic particle flows, and the monitoring of geomagnetically induced currents in four strategic substations of the national electrical system. Finally, the places where the aurora borealis aurora were seen are discussed.
