    On November 2, 2003 at 17:03:00 UT a solar flare, registered by the GOES satellite, was also recorded by the Neutron Monitor (NM64) of Cosmic Ray Laboratory at Mount Chacaltaya. This flare affected the local geomagnetic field (F): there were variations in the intensity of the horizontal component (H), declination component (D) and vertical component (Z). Variations on these components, estimated as 71 nT, 10 deg. and 19 nT, respectively, have been observed with the Patacamaya’s Geomagnetic Observatory; as well as a net increased field (F), estimated as 66 nT, recorded by the Villa Remedios Geomagnetic Observatory. The duration of the magnetic and neutron signals was approximately 40 and 54 minutes, respectively, which shows that the flare was intense and with large emission of neutrons.
