A few notes on Universal and Local Time

Coordinated Universal Time (UTC) is a world time that is not affected by any time zone or seasonal time changes, and is defined by a network of Atomic Clocks. Historically, but incorrectly, it is often compared to Greenwich Mean Time (GMT), which is an Astronomical time (related to Earth rotation).
UTC has many applications whenever a uniform, accurate world time system is required, such as Astronomical events. UTC is also the basis for all Local (Civil) time systems in the world.
Occasionally (usually 1 January or 1 July) UTC is corrected with a leap second, to keep it within a tolerance from Astronomical time, compensating for the fact that Atomic Time is running a bit fast as compared to the rotation of the Earth. In contrast to what many claim, this is NOT because of the slowing down of Earth rotation, which is five orders of magnitude less than the application of leap seconds.

Find more general information on UTC here.

Time zones
The world is divided in time zones in which local (or civil) time is offset by a fixed amount from UTC. Most often this offset is an integer number of hours, although some countries have other offsets. However the UTC seconds are the same everywhere.
Any difference at the level of seconds in the above displays is not realistic; these services do not claim accuracy to that level.
Accurate UTC can be found on the USNO Master Clock (top right on the page)).

Daylight Saving Time
Daylight saving time (DST), (aka Summer time), is the convention of advancing clocks so that afternoons have more daylight and mornings have less.
Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn. The dates that this happens vary by location and change occasionally. In 2007 both the USA and New Zealand have changed their definition of DST.

New Zealand
New Zealand Standard Time (NZST) is defined as UTC + 12 hours.
During the southern summer, New Zealand has Daylight Saving Time (NZDST) which is defined as UTC + 13 hours.
NZDST starts on the last Sunday in September at 2 am when the clocks are set to 3 am.
NZDST ends on the first Sunday in April at 3 am when the clocks are set to 2 am.

We are coming out of the current sunspot cycle 24 which will end around 2019. The maximum of this cycle has yet again been well below that of the previous two cycles.

“Some studies show that sunspot magnetic field strengths […] are already close to the minimum needed to sustain sunspots on the solar surface”.

Teachers invited to join the STEAM Team

STEAMThe Planetary Society is developing a youth education program with the goal to help teachers educate and engage students around the world in Science, Technology, Engineering, Math, and the Arts.

The STEAM Team is an advisory network of educators from around the world who will help to create the most effective education program possible. We want to bring your educational expertise to bear on a widespread program to enhance STEAM education around the world.

By joining this team, you will become part of a global advisory council of educators. We will reach out to you for feedback on the educational resources we develop, and on the direction of our youth education program as a whole. We’ll send you surveys, questions, and opportunities to share your ideas.
