- Sunspot Pair May Have Erupted With 'Sympathetic Solar Flares' - MSNWhen sunspots erupt at nearly the same time, it could be something known as "sympathetic solar flares." A double eruption from sunspots AR3614 and AR3615 may be an example of it. One of the flares ...
- Sunspots/Solar Cycle | NOAA / NWS Space Weather Prediction CenterThe largest sunspot groups can cover large swaths of the Sun’s surface and be many times the size of Earth. Sunspot groups that are clearly visible and observed by designated ground-based observatories, are assigned a NOAA/SWPC 4-digit region number to officially record and track the sunspot group as it rotates across the visible solar disk.
- Sunspot - WikipediaSunspot number is correlated with the intensity of solar radiation over the period since 1979, when satellite measurements became available. The variation caused by the sunspot cycle to solar output is on the order of 0.1% of the solar constant (a peak-to-trough range of 1.3 W·m −2 compared with 1366 W·m −2 for the average solar constant).
