1. 1. Modeling the complex ejecta on 2017 September 6-9 with WSA-ENLIL+Cone and EUHFORIA

   University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Anita Linnéa Elisabeth Werner; [2018]
   Keywords : CME; space weather; forecast; prediction; WSA-ENLIL Cone; EUHFORIA; preconditioning; type II radio burst; kmTII; dcld; September 2017; geoeffective;

   Abstract : Three CMEs which erupted on 2017 Sep 4 and 6 underwent mutual interaction before reaching Earth on Sep 6-9, where it gave rise to a complex and unexpectedly geoeffective structure as detected by WIND at L1. The spacecraft first observed an interplanetary (IP) shock on Sep 6 followed by a turbulent sheath. READ MORE

3. 2. Comparison of the shock arrival times for Earth-directed ICMEs provided by the WSA-Enlil+Cone model and in-situ observations at L1: A Case Study

   University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Anita Linnéa Elisabeth Werner; [2016]
   Keywords : CME; ICME; CIR; WSA-Enlil Cone; CCMC; ACE; SAT; St. Patrick; Sun-Earth connection;

   Abstract : A case study which examines the agreement between prediction and data is performed for three, complex interplanetary shocks which were detected at the Sun-Earth Lagrange point L1 and induced moderate to intense geomagnetic storms. We use model output from previous runs of the coupled coronal-heliosphere WSA-Enlil+Cone model, available through the Community Coordinated Modeling Center (CCMC), and in-situ data from the OMNI data set.
