Solar activity as observed by neutron monitors and muon telescopes in the same location

In this paper we present the advantage of observing solar activity with neutron monitors and muon telescopes operated from the same location. This combination of detectors multiplies the information that would be collected with only one of these instruments. Not only the observation of different types of secondary cosmic rays but also the observation at different energy thresholds with some information on the directionality of muons. As an example of the above, we analyze the GLE73 and the Forbush decrease associated with the same solar event.
