NASA Rocket 36.336 Extreme Ultraviolet Spectrum	Woodraska, D

Laboratory for Atmospheric and Space Physics, University of Colorado
The NASA sound rocket 36.336 was successfully launched from White Sands Missile Range on June 18, 2018 near solar minimum conditions with a payload consisting of a suite of instruments measuring the solar irradiance. The payload included twin instruments to the SDO EUV Variability Experiment (EVE) Multiple EUV Grating Spectrograph (MEGS) detectors. Absolute calibration of the payload is performed using a primary irradiance standard, the NIST Synchrotron Ultraviolet Radiation Facility (SURF) in Gaithersburg, MD. The reduced solar spectrum from 6-105 nm provides the calibration to SDO-EVE and other extreme ultraviolet irradiance measurements. Determining the calibrated spectrum involves several ground and flight corrections, data analyses, data reduction, and modeling atmospheric absorption. Ground calibration includes determining several factors: the absolute calibration at SURF (responsivity), the angular pointing dependence in the field of view (FOV), higher order spectral contributions, and the temperature dependence (gain and dark). Flight data is used to determine additional information such as the wavelength scale using solar lines, a dark current correction that also removes low-frequency noise, and an algorithm to reduce the images to spectra. The radar tracking data is used in conjunction with the NRL-MSISE00 model to remove the absorption from the thermosphere/ionosphere.

The Helioviewer Project enables heliospheric data visualization, supporting data from multiple missions and instruments. It enables the visualization of petabytes of solar data from SDO and other missions, and provides tools to create downloadable media, track solar events, and access the science data behind the images. We discuss the latest changes to Helioviewer Project services, in particular the web client helioviewer.org, the provision of images from the Mauna Loa Solar Observatory, and support for the labeling of celestial bodies and the orbits of the Parker Solar Probe and the Solar Orbiter. We discuss the use of the Helioviewer Project API to develop a helioviewer.org user interface aligned with US middle and high school instructional use, available at student.helioviewer.org, created specifically for students. This client offers many of the same features of the fully fledged helioviewer.org, but is streamlined to lower the barrier to entry. This new client provides the means to access targeted observation layers which serve to highlight a subset of the available observations and events that are aligned with educational standards, making it easier to dive-in and begin the process of discovery. The new client student.helioviewer.org and associated educational resources, has been developed in conjunction with WGBH’s Bringing the Universe to America’s Classroom Project and distributed on PBS LearningMedia. We discuss the usage of this client in comparison to helioviewer.org and describe how student.helioviewer.org can drive a back-end redesign of Helioviewer Project services to take full advantage of cloud computing architectures.

The optical solar physics group at AIP is responsible for the GREGOR Fabry-Perot Interferometer (GFPI) and the large-format facility cameras (Blue Imaging Channel (BIC) and High-resolution Fast Imager (HiFI)) at the 1.5-meter GREGOR solar telescope (Tenerife, Spain). Since the »Early Science Phase« of the telescope in 2014, the group developed a data reduction pipeline for these two instruments. The pipeline »sTools« is based on the Interactive Data Language (IDL) and delivers reduced and image-restored data with a minimum of user interaction. Furthermore, it creates quick-look data and builds a webpage with an overview of the observations and their statistics (http://gregor.aip.de). However, during the last years, sTools continuously evolved and currently hosts many additional routines for data analysis: (1) A local correlation tracking (LCT) algorithm adapted for both high-resolution (GREGOR and Hinode) and synoptic full-disk (SDO) data. (2) A new quantitative tool, i.e., a Background-subtracted Solar Activity Map (BaSAM), to assess and visualize the temporal variation of the photospheric magnetic field and the EUV 160 nm intensity. This method utilizes SDO data and is applicable to both full-disk observations and regions-of-interest. (3) Calibration of synoptic full-disk data from the Chromospheric Telescope (ChroTel) including extraction of Doppler velocities from He I 1083 nm filtergrams. (4) Analysis tools for sun-as-a-star spectroscopy for the Solar Disk-Integrated (SDI) telescope of the Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI). sTools is licensed under a creative commons license and is freely available, after registration, at the abovementioned website.

MEDOC, created as the European data and operations center for SoHO, hosts also data from STEREO, SDO, and various other solar physics missions. The SDO archive at MEDOC represents more than 415TB of data, and covers the full length of the mission. It includes aia.lev1 data at a minimum cadence of 60s in the EUV channels (12s at specific periods of interest), and most of the 720s-cadence HMI series. It is complemented by a database of DEM maps derived from AIA. MEDOC provides a reliable, convenient, and fast (especially for European users) access to these SDO data, by a web interface and webservices. We also provide IDL and Python clients to these webservices, allowing complex queries and automated analyses on large datasets to be made.

As LASP expands its processing capabilities to other platforms and programming languages, an effort was initiated to add functionality to SunPy for the search, download and processing of EVE data. This effort extends SunPy’s Fido search and download capabilities to gather and download EVE’s level 2 and 3 data products as well as ESP’s level 1 data product. SunPy’s Timeseries module has also been modified to ease the reading, plotting and analysis of EVE data.
The NASA Space Science Education Consortium (NSSEC)	Young, A

NASA Goddard Space Flight Center
The NASA Space Science Education Consortium (NSSEC): Through the Eyes of NASA to the Hearts and Minds of the Nation, provides NASA science education and public outreach programs across all SMD space science discipline divisions (heliophysics, planetary science, astrophysics, astrobiology) to broad and diverse audiences throughout the United States. Central to our program is the concept of One Accessible Universe or 1 AU. Through 1 AU, we will emphasize the necessity of making NASA space science education accessible to the country, reaching diverse populations through focused communications including facilitating access and usability for people with physical disabilities. The NSSEC emphasizes cutting edge educational technology applications, high impact NASA Big Events, and data driven science education experiences, leveraging a suite of over 30 partner organizations to reach and extensively impact undergraduate education, after school programs, informal education venues, amateur astronomers, civic groups, underserved populations, and the general public. Here we present an overview of our program especially its support of solar science.
Low Latency Space Weather Products from SDO-EVE	Jones, A

University of Colorado, LASP
The S-band house-keeping link from SDO has very low latency. The SDO-EVE-ESP downlinks a very small amount of data through this housekeeping channel, and we have been able to use these products to provide a near real-time EUV line irradiances and a proxy for the GOES XRS channels. These data are publicly available as the EVE Level 0CS data and plots.
