Meeting Support kindly provided by: 2 AIMS of the Workshop The workshop is aimed at highlighting the current state of knowledge regarding High Speed Solar Wind Streams and their interaction with Geospace - from the Earth’s atmosphere, out through the Earth’s magnetosphere to the solar wind. Knowledge of this field has progressed significantly during the past few years, and it is timely to bring together workers in this research area to discuss recent progress, and the outstanding physics questions to focus on in the future. The aim is to create a workshop-type atmosphere where frank discussion of current topics of interest is encouraged. To maintain this format the workshop will be limited to a maximum of 40 delegates. SCIENCE QUESTIONS 1. What determines solar wind/magnetosphere coupling efficiency during HSS? How important are fluctuations in solar wind velocity, pressure, and magnetic field? 2. Are different magnetospheric modes more likely during high speed streams? 3. How are Pc5 waves made? Which process dominates? Why are Pc5 waves so dominant in HSS events? 4. Which waves are the most important for acceleration/loss of radiation belt particles? How can we quantify the relative wave-particle loss rates? What is the MLT dependence? 5. What is the electron energy dependence in response to HSS-driven acceleration and loss? Does this vary with other drivers of acceleration and loss? 6. What response do high speed streams initiate within the atmosphere? How can we test coupling mechanisms between different atmospheric regions? 7. Precipitation of energetic (>100 eV) electrons - what implications for the lower atmosphere? 8. What are the ionospheric/atmospheric responses to particle precipitation? Are there differences in these responses between HSS and other precipitation events? 9. What is the role of the ring current composition during HSS? What is the main ring current injection mechanisms? Why is the Dst response relatively weak (but of long duration) during HSSs? The 2009 workshop will aim to address these questions (and others) and make genuine progress in understanding HSS/Geospace interactions. At the 2007 meeting we agreed to choose two events for coordinated study. These events were: 10-22 October 2003 10-16 November 2003 If you have data for these events, please bring it to the workshop. 3 Sunday 6th September 2.00-6.00 pm REGISTRATION: 6.00-7.00 pm ICEBREAKER (University of Cumbria Reception). 4 Monday 7th September : 8.45 am – 8.10 pm SESSION 1 : CIRs and High Speed Streams in the Solar Wind Chair: Mick Denton 8.45 Welcome : Meeting Logistics : Questions to be Answered : Progress since 2007 Mick Denton 9.00 Overview of CIRs in the Solar Wind John Steinberg 9.40 The Reaction of the Magnetosphere to Coronal Interaction Regions: The Denton-Borovsky Superposed Epoch Studies Joe Borovsky 10.20-10.40 -------------------------------------------REFRESHMENTS------------------------------------------------ 10.40 The Rise and Fall of Open Solar Flux During the Current Grand Solar Maximum Mike Lockwood 11.20 CIRs and High Speed Streams in the Solar Wind Kalevi Mursula, J.

To take advantage of the workshop location there will be two guided walks on Monday and Friday of the workshop, starting at TBD from the entrance to Univeristy of Cumbria on Rydal Road (near the mini-roundabout). Details of these trips will be available at the workshop. Boat Trip to Bowness-on-Windermere: Wednesday (assemble in lobby of University of Cumbria at TBD) A boat tour will take delegates to Bowness-on-Windermere. Windermere is the largest lake in England and weather permitting, allows great views of the surrounding countryside. Bowness-onWindermere is around a 15 minute walk from the town of Windermere proper. RETURN from Bowness at TBD prompt - the ferry won’t wait!! Around Ambleside: The area around Ambleside contains numerous public footpaths, hills, streams and valleys. In good weather there is nothing better than exploring the area on foot. One of the most frequent causes of walkers experiencing a problem when straying off the beaten track is the UK climate. Weather conditions can deteriorate very quickly and fog, rain, sleet and snow all may occur in September. If you do go exploring off the beaten track use your common sense. 1. Inform someone where you have gone and what time you expect to be back. 2. Wear good boots and carry a waterproof coat. 3. Check the weather report before you leave. Contact a local organiser if you would like further advice on likely conditions in the area. Workshop Meal and Céilidh The workshop meal will be held on Wednesday evening, and will be followed by a céilidh. For those of you unaware of what this entails, Wikipedia provides a good introduction http://en.wikipedia.org/wiki/Ceilidh Dress is informal. Dancing is compulsory!!! 1 UC Reception HILLTOP 1
