Analysis of Acoustic Emission from "Quiet Sun Areas"

In this talk I will present  the acoustic, magnetic and chromospheric  properties  of different types of  Quiet Sun: the Quiet Sun surrounding active regions, the Quiet Sun under a coronal hole and a ‘plain’  Quiet Sun.

Learning to Diagnose Coronal Heating Signatures in Transition Region Spectral Lines

In the work reported here we have investigated signatures of nanoflare-based coronal heating in transition region radiative emission. The transition region is brighter, but very strongly coupled to the corona, and responds quickly to changing coronal conditions. Direct signatures of coronal nanoflares are expected to be extremely difficult to detect and perhaps only through such indirect observations may we find sufficient evidence to pin-down the coronal heating mechanism.

A FURST look at the VUV Sun as a Star

Thanks to the Hubble Space Telescope, we know the input of radiation from Alpha Cen A to our solar system far better than that of our own Sun.  The Full-Sun Ultraviolet Rocket Spectrometer (FURST) will obtain the first moderate resolution (R > 104), radiometrically calibrated VUV spectrum of the Sun-as-a-star. I will describe the instrument design, scientific prospects, and broader impacts of the mission.

Register for the 2018 Unidata Users Workshop

The Unidata Users Committee invites you to join Unidata staff, community members, and distinguished speakers this June in Boulder, Colorado. The goal of this year's workshop is to raise awareness of the current trends in the academic geoscience community with an emphasis on Data Proximate Analysis, Machine Learning and Data Analytics, Using GOES-16 Data, and Working with Ensemble NWP Output.
