Since May 1, 2008 periods of instrument noise began appearing in the
Thule Neutron Monitor data. The problem is being investigated.

                  Thule Neutron Monitor Data Lists

Thule Neutron Monitor lists for 1-minute and 5-minute data.
Data is sent from Thule in near real-time. Records are received 
every 5-15 minutes with data 5 minutes before current time.

Conversion Factor: SWPC Counts/minute * 6.0755 = Counts/Hour/100 
This gives values that agree with the Thule Real-time Data in 
Counts/Hour/100 at http://www.bartol.udel.edu/realtime/thule.html

NO QUALITY control has been performed.
This data SHOULD NOT be used for scientific research.

Preliminary data with basic quality checks, and Final Thule 
Neutron Monitor data (plus other stations) is available 
online at   Bartol Research Institue, University of Delware
           http://www.bartol.udel.edu/~neutronm/

Other real-time Neutron Monitor data available at
            http://neutronmonitor.ta3.sk


The file format follows the SWPC standard data list 
conventions where header lines start with either # or :. 

Daily files are named with the UT day of the data. They
are online for 90

The file with no date contains data for the last 
2-hours. Users retrieving data frequently can copy these 
shorter files.

The 1-min data lists update every minute. The 5-min lists
every five minutes beginning at minute 3.
