  1. TItle: Solar Flare database
    --
     
  2. Source Information
    -- Donor: Gary Bradshaw gbradshaw@clipr.colorado.EDU
    -- Date: 3/89
     
  3. Past Usage:
    -- Gary Bradshaw: (Class Attributes were collapsed to 0 and >0)
    -- See the past-usage file for a note written by Gary Bradshaw
     
  4. Relevant Information:
    -- The database contains 3 potential classes, one for the number of times a
    certain type of solar flare occured in a 24 hour period.
    -- Each instance represents captured features for 1 active region on the
    sun.
    -- The data are divided into two sections. The second section (flare.data2)
    has had much more error correction applied to the it, and has
    consequently been treated as more reliable.
     
  5. Number of Instances:  flare.data1: 323, flare.data2: 1066
     
  6. Number of attributes:  13 (includes 3 class attributes)
     
  7. Attribute Information:
  8. Code for class (modified Zurich class)  (A,B,C,D,E,F,H)
  9. Code for largest spot size              (X,R,S,A,H,K)
  10. Code for spot distribution              (X,O,I,C)
  11. Activity                                (1 = reduced, 2 = unchanged)
  12. Evolution                               (1 = decay, 2 = no growth,
    3 = growth)
  13. Previous 24 hour flare activity code    (1 = nothing as big as an M1,
    2 = one M1,
    3 = more activity than one M1)
  14. Historically-complex                    (1 = Yes, 2 = No)
  15. Did region become historically complex  (1 = yes, 2 = no)
    on this pass across the sun's disk
  16. Area                                    (1 = small, 2 = large)
  17. Area of the largest spot                (1 = <=5, 2 = >5)
     
    From all these predictors three classes of flares are predicted, which are
    represented in the last three columns.
     
  18. C-class flares production by this region    Number
    in the following 24 hours (common flares)
  19. M-class flares production by this region    Number
    in the following 24 hours (moderate flares)
  20. X-class flares production by this region    Number
    in the following 24 hours (severe flares)
     
  21. Missing values: None
