Today’s Sun, seen through a filter of ‘visible’ light (remember: NEVER look directly at the Sun!), as viewed by the Solar Dynamics Observatory (SDO), by the Helioseismic Magnetic Imager (HMI). This image is known as a ‘continuum’ image; a continuum image is formed by filtering portions of the visible light part of the spectrum. The SDO HMI is designed to study oscillations and the magnetic field at the solar surface, or photosphere.
The continuum images allow us to track the evolution of sunspots. These images are important as they allow us to better understand the dynamic nature of the solar atmosphere.

TRENDS IN TECHNOLOGY
Radio Automation Grows With the Times
Twenty years ago, as consolidation among radio companies was running rampant, automation systems became even more important. Radio companies were promising new efficiencies, and automation provided one way to achieve that. Most manufacturers that work in this space have developed at least several generations of new systems since, with dramatically more power and functionality.
21st CENTURY PD
Is There Life After 55 for Radio?
“As of 2018, 90.6 million Americans are now over the age of 55 — 28 percent of the population. Most are Baby Boomers who have been passionate about radio throughout their lives. They are adopting new audio technologies but at a slower rate than younger people. They’re not stuck in the past, but some observers might say radio is,” Dave Beasing argues in his latest column.

Dial Report and Ad-ID Seek to Standardize Radio Spot Tracking
Collaboration is intended to “illustrate the effectiveness” of radio ads
TagStation subsidiary Dial Report said it is collaborating with Ad-ID to establish tracking standards for the radio industry.
“It is clear that the radio industry would benefit from having the same tracking standards that the TV and digital industries enjoy today,” said Dial Report Senior Vice President of Revenue Generation Lisa Pike in an announcement. TagStation is part of Emmis Communications but is seeking to build a data-based ecosystem to serve the broader radio industry, in part built around user data collected via its NextRadio app.
Ad-ID Executive Director Harold Geller said the collaboration is intended to “illustrate the effectiveness” of radio ads through spot tracking.
According to the announcement, spot tracking provides insight into how radio drives consumer action and correlates this information to “when the spot aired, what stations it played on” and listeners’ behavioral and demographic information. The addition of Ad-ID codes will help to fill in gaps in information previously left by “antiquated advertising asset codes within station trafficking,” the companies said.
“The first and most valuable step in our data attribution process is to verify that all spots, across our entire network of broadcasters, belonging to a brand are identified correctly,” said Dial Report Senior Vice President of Product Development Ben Husmann. “Dial Report uses the Ad-ID API to fill in the blanks and expand spot metadata to include accurate and complete information such as advertiser, product, copy points and more. It’s particularly helpful when we need specifics on multiple creative from one brand.”
TagStation describes Dial Report as a first-party data platform measuring radio performance. Ad-ID is an ad industry joint venture of the American Association of Advertising Agencies (“4As”) and the Association of National Advertisers.

Did you know? Here’s a space weather and radio propagation educational tidbit – from http://SunSpotWatch.com – at 14:00 UTC on 2018-04-25:
X-ray flares are classified by x-ray brightness in wavelength range 1 to 8 Angstroms. Three main categories for X-ray flares: ‘C’ ’M’ and ‘X’; C-class=minor,X-class=major.
X-class flares are big! A flare that is measured in the X-class range is a major event that could trigger planet-wide radio blackouts. An X-class flare could also cause a long-lasting radiation storm and proton event. The effect on the ionosphere may last many hours, when the flare is extremely powerful.
M-class flares are medium-sized; they can cause brief radio blackouts (lasting mere minutes, or a few hours). Minor radiation storms sometimes follow an M-class flare.
By the way, a Polar Cap Absorption (PCA) Event is caused by the radiation storms triggered by flares, and the bigger the flare, the more intense the PCA may become.
Compared to X- and M-class events, C-class flares are small. They have a minor effect on the ionosphere, and therefore on radio communications are not so terribly affected.

Today’s Sun (artificially-colored in yellow) seen at the…
Today’s Sun (artificially-colored in yellow) seen at the 171-angstrom wavelength (Extreme Ultraviolet, or EUV), as viewed by the Solar Dynamics Observatory (SDO), by the Atmospheric Imaging Assembly (AIA).
At this wavelength, at a wavelength not seen by the un-aided eye, we observe the Sun with the 17.1 nm (171 A) filter. This Extreme Ultraviolet (EUV) waveband is used to monitor the corona and upper transition region. With this filter, we can see the myrid of massive magnetic field lines, from simple to complex, that weave and twist throughout the Sun.
The image is a ‘false color image’, meaning that observed data are in a range outside of what human eyes can see, so the data are digitally recast into colors that emphasize physically important features. This view is created from data gathered by the Solar Dynamics Observatory (SDO) satellite that flies above Earth’s atmosphere in an inclined geosynchronous orbit.
Emissions captured in this image come from iron (Fe), a trace element in the solar atmosphere that emits Extreme Ultraviolet (EUV) light when heated to temperatures in excess of one million deg K. In the solar corona the temperatures are so high that most chemical elements have lost many of their electrons. Some of the remaining electrons still attached to the atom emit EUV radiation in narrow wavebands or lines.
The 17.1 nm filter, or channel, is dominated by emissions from highly ionized iron: 8 times ionized (missing 8 electrons) iron–Fe IX. The roman numeral descriptors are consistent with spectral notation: the level of ionization for a given roman numeral is one unit larger that the actual number of missing electrons. The temperatures associated with this level of ionization is about 6 x 10^5 K.
The bright regions in this image correspond to regions of closed magnetic field loops that trap the hot, emitting plasma. Large bright regions are often called active regions. The dark regions correspond to cooler temperatures and possibly to locations where magnetic field lines open into the heliosphere, and thus, do not trap hot plasma.

Latest TEC map from NASA. What is TEC? Total Electron Content…
Latest TEC map from NASA. What is TEC? Total Electron Content (or TEC) is an important descriptive quantity for the ionosphere of the Earth. TEC is the total number of free electrons integrated between two points, along a tube of one meter squared cross section, i.e., the electron columnar number density. Affected by solar activity, Total Electron Content (TEC) describes the total number of free electrons present within one square meter between two points (i.e. between the receiver and satellite involved in measuring TEC).
These maps are also used to monitor ionospheric weather, and to nowcast ionospheric storms that often occur responding to activities in solar wind and Earth’s magnetosphere as well as thermosphere.
