Self-Introduction

  • Name: Yuki Obana
  • Position: Associate Professor
  • Division: Department of Engineering Science, Faculty of Engineering, Osaka Electro-Communication University
  • Phone: +81-72-825-4593
  • Location: Y321

I started working at Osaka Electro-Communication university in April 2010.
I like traveling, watching formula-1 races, and visiting formula-1 venues. I have visited the city courses of Melbourne, Singapore and Monaco and walked around the course. Someday, I would like to visit and walk the city course of Montreal in Canada!

My research target is the near-earth space, which is called the magnetosphere or geospace. In this region, many artificial satellites fly, and recently, astronauts are always staying at the International Space Station. I am investigating environmental changes in this region based on analysis of various observation data.

Recently, I am studying the plasmasphere, which is the cloud of ionized gas escaped from the earth's atmosphere. In addition, I am studying the minute fluctuations of the magnetic field of the Earth. They tells us how the magnetosphere and ionosphere are electro-magnetically coupled.

I am also engaged in activities to obtain new observation data. My collaborators and I are particularly focusing on observing the slightest fluctuations in the magnetic field coming from space to the ground. Since the signal coming from space is very weak, it is necessary to make high-precision observations in a quiet environment and avoid various noises generated by human activities. It is very exciting to analyze the new observation data, which are finally obtained after hard works and efforts!

The observation data of the CRUX magnetometer network (Click here for details), which has been operating in New Zealand since 2011, are open to the world. From 2019, a new research project started to reveal the mystery of the loss of the radiation belt particles. We will additionally install an aurora all-sky camera and an induction magnetometer in New Zealand (see here for details). in addition, I am a collaborator of the PWING project, which establishes eight observation points surround the Arctic Circle and investigates the acceleration and loss of radiation belt particles. In 2016, the geospace exploration satellite ERG / Arase launched by the Japan Aerospace Exploration Agency (JAXA). I am participating in the ERG ground observation team and the ERG magnetometer PI team.

Why don't you join the our laboratory and explore the mystery of the space together?
