Joanne says: Jordi is my miracle grandson. While his doctor says he is ready for a Safta visit (that’s me) – I have to know I’m not an asymptomatic disaster before I spend time with him.
Yesterday there is a close inferior conjunction of Venus, which is a technical term for meaning that Venus has an apparent close approach to the Sun. It's not a full transit, but we don't need transits to see it, because we have a coronagraph at MLSO.
Philip Judge is a senior researcher in physics at the High Altitude Observatory. Education and outreach has been a major focus and passion during his scientific career. He has influenced and encouraged many young scientists to pursue careers in solar physics.
Mausumi Dikpati is a senior scientist at HAO. She studies the dynamics between Rossby waves and solar activity such as flares and coronal mass ejections (CMEs).
Philip Judge states that the interpretation of emission lines formed in large astrophysical plasmas such as the solar atmosphere faces many challenges. Relatively simple line-ratio estimates of physical parameters, while appealing, are heavily laden with assumptions.
We report the first results of a global ionosphere/thermosphere simulation study that self-consistently generates large-scale equatorial spread F (ESF) plasma bubbles in the post-sunset ionosphere.
Summary or Abstract: The strength and structure of the Earth's magnetic field is gradually changing. These changes do not only affect the difference between the geographic and magnetic pole, which we have to consider when we hike in higher latitude regions.
