In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

The solar magnetic field exhibits a 22-year cycle manifested by the
sunspots. The cycle arises from the dynamo process that maintains the
large-scale magnetic field. It is shown that essential ingredients for
the solar dynamo are large-scale flows (differential rotation,
meridional flows), and turbulence affected by rotation (turbulent
alpha-effect). A standard axisymmetric model working in a 2D spherical
shell and making use of the equations of mean-field magnetohydrodynamics
is presented along with a few representative results. Such models may help
to predict the strength of the next solar maximum. Such predictions
have become critical in deciding about space missions (for example whether
it is advisable to pay for maintenance of the Hubble Space Telescope!)
Empirically one knows that the strength of the so-called dipole moment
during the declining phase of the previous cycle is related to the strength
of the following maximum. Recently solar dynamo models have been used
to make predictions about Solar Cycle 24 (maximum due around 2012) with
rather different outcomes. These techniques will be reviewed and their
respective merits and deficiencies discussed.
