Neutron monitor data 1995-1996, and during the solar event of 3-9 November 1997
Below are shown hourly corrected cosmic ray plots from the Oulu
and Thule high-latitude neutron monitors from the beginning of
1995 until the end of 1996. These data have been retrieved from
system. Data for 1997 will be online in that server soon. The
vertical cut-off rigidity for both Oulu and Thule stations is <1
GV. Note the clear ~27-day variation, particularly in 1996, in
both of the data sets.
The large solar event of 3-9 November 1997 was also seen by several
neutron monitors. Preliminary data from Moscow, Tixie Bay, and
Apatity stations have been provided to us by the IZMIRAN
Cosmic Ray Department in Moscow, and are included in the TEC-EES Solar Energetic Proton
Events WWW page.
