The Sun is at solar maximum! Solar Cycle 24 is seeing a second, higher peak in the sunspot number.

The Sun is at solar maximum! Solar Cycle 24 is seeing a second, higher peak in the sunspot number.

The Sun is in the midst of its "maximum phase," though modest when compared with recent cycles. Data and imagery show the comings and goings of sunspots, markers of the strong local magnetic fields that cause the eruptions commonly thought of as space weather. Forecasters expect intermittent activity to continue throughout 2014 and continuing for the rest of the solar cycle. At times the activity will be significant. Watch the SWPC web site for news of those times.
