The dates and location for the 2019 International EISCAT symposium have been announced. It will be held in 19–23 August 2019 at the University of Oulu, Finland. A radar summer school will be held in the preceding week, and a full announcement and website will follow soon.

Given that EISCAT 3D is scheduled to come on-line in 2021 this is a great opportunity to develop new collaborations, get up to speed on the science EISCAT can facilitate (including E3D), and give students/postdocs a head start in working with the new system.
EISCAT has put together some cartoons showing how EISCAT 3D will operate under different scenarios including simultaneous multi-user experiments. Check out these illustrations of the beam switch timing and ability to switch between modes on the order of a second!
An RAS Specialist Discussion meeting entitled "30 Years of Planetary Astronomy with H3+" will be held on 14 December 2018 at the Royal Astronomical Society at Burlington House. This meeting is co-convened by Steve Miller (UCL) and Nick Achilleos (UCL), and further details on the meeting is available here.
The meeting abstract is as follows:
2018 marks the 30th anniversary of the serendipitous discovery of the H3+ molecular ion in Jupiter’s northern aurora. The discovery itself was the result of an impromptu collaboration between astronomical observers, telescope instrument builders, laboratory spectroscopists and molecular physicists. H3+ emission has subsequently been detected from Saturn and Uranus, of the Solar System’s giant planets, but not Neptune. As an energetic and reactive molecular ion, H3+ is now used as a tracer for energy inputs, via particle precipitation, into giant planets’ atmospheres from their enormous magnetospheres: variations in emission levels are used to monitor both shorter-term magnetospheric dynamics, caused by changes in internal (plasma density) and external (solar wind dynamic pressure) factors, and longer-term changes that may result from the solar cycle and seasonal changes in solar irradiation. The final results from Cassini – particularly the VIMS instrument – and new measurements from JUNO mean that there is a wealth of data to add to and complement that being generated from ground-based observations. All-in-all, there is a wealth of material to review and huge current interest in just how this simple molecular ion behaves and what it tells us about planets in our Solar System and beyond.
