SUMMARY:Guest Speaker - Prof Michael Wheatland (University of Sydney)
LOCATION:Green Point Observatory
DESCRIPTION:Solar Activity\nSolar activity describes dynamic behaviour at the Sun drive
n by the Sun's magnetic field. The most obvious manifestations of solar act
ivity are sunspots, which represent locations at the photosphere where inte
nse magnetic fields emerge into the Sun's outer atmosphere, the solar coron
a. Large scale solar activity (solar flares and Coronal Mass Ejections) inv
olve gigantic magnetic explosions in the corona. These events are of intere
st in themselves, but they also influence our local space environment, prod
ucing space weather storms with the potential to cause damage to communicat
ions infrastructure and power systems on Earth. This talk describes sunspot
s, solar activity, the current state of the solar cycle, and our understand
ing of flares, CMEs, and space weather.\n \n\nProfessor Michael WheatlandSy
dney Institute for Astronomy, School of Physics, The University of Sydney\n
is a solar astrophysicist with more than 20 years' experience, and the auth
or of more than 80 publications in the field. His research interests includ
e solar activity, solar flare statistics, coronal magnetic fields, coronal
heating, and solar-terrestrial relations. Mike is an Editor in Chief at the
journal Solar Physics.\n
