Solar and Geomagnetic Activity - what does it mean?

  1. Nov 29, 2012 #1
    Referring to following statements, I am very confused on how to interpret their forecasts.

    Does it mean as shown below?

    A decrease to low levels?
    An increase to low levels?

    • low levels from 26 November - 01 December?
    • low levels from 02 - 04 December?
    • low levels for the remainder of the period?

    Does anyone have any suggestions?
    Thanks in advance for any suggestions

    Forecast of Solar and Geomagnetic Activity
    26 November - 22 December 2012

    Solar activity is expected to be at low levels with a chance for
    M-class flares from 26 November - 01 December as Regions 1620 and
    1618 evolve and rotate off the visible disk. A decrease to low
    is forecast from 02 - 04 December. An increase to low levelswith a slight chance for M-class flares is expected for the
    remainder of the period as Regions 1612, 1618, and 1620 return.
