Explanation:
In this composite cityscape,
dawn's
first colors backdrop the
lights along Brisbane's skyline
at the southeastern corner of Queensland, Australia,
planet Earth.
Using a solar filter, additional exposures made every 3.5 minutes
follow the winter sunrise on July 8 as
planet-sized
sunspots cross the
visible solar disk.
The sunspots mark
solar active regions with convoluted
magnetic fields.
Even as the maximum in the
solar
activity cycle begins to fade, the active regions produce intense
solar
flares and eruptions launching coronal mass ejections (CMEs),
enormous clouds of energetic particles, into
our fair solar system.
