2017 Total Solar Eclipse News

By Bill Liles, NQ6Z

Editor’s Note: The HamSCI-related eclipse efforts comprise of a number of sub-projects. This article describes the EclipseMob project, which is an experiment led by a team at George Mason University and the University of Massachusetts at Boston. EclipseMob will study eclipse-driven ionospheric effects using the Very Low Frequency (VLF) and Low Frequency (LF) bands. Results of this experiment could aid in understanding propagation at the proposed 2,200 meter ham band.

Since 1912 there have been many efforts to collect and analyze data during a solar eclipse to help understand the ionosphere. These efforts have been conducted in frequencies ranging from VLF to VHF.  In most cases, individuals or small teams have collected data from disparate transmitters.

HamSCI scientists met at the Fall American Geophysical Union (AGU) meeting in San Francisco during the week of December 11–17, 2016. The Fall AGU meeting is one of the largest gatherings of geoscientists in the world, with approximately 24,000 people attending. During the meeting, HamSCI scientists presented ham radio-based research, discussed possibilities for upcoming experiments, and networked with members of both the Citizen Science and Space Science Communities.

On October 19 – 20, 2016, two new Reverse Beacon Network (RBN) receivers were installed at the United Astronomy Clubs of New Jersey (UACNJ) Observatory at Jenny Jump State Park in Hope, NJ. These receivers, assigned call signs K2MFF-2 and K2MFF-3, are sponsored by the New Jersey Institute of Technology Center for Solar-Terrestrial Research (NJIT-CSTR). These receivers will listen for amateur radio Morse Code signals on the high frequency (HF, 1.8–30 MHz) bands and report “spots” back to the main RBN web site. These spots will be used by ham radio operators to find other hams to communicate with, and by scientists to study shortwave propagation and the ionosphere.

In “The Reverse Beacon Network” (Oct. 2016 QST, pp. 30-32), Pete Smith, N4ZR, and Ward Silver, N0AX explain how the Reverse Beacon Network (RBN) is used to observe and report both CW and RTTY communications to the DX spotting network and to a data archive. This article explains how to be spotted by the RBN, how to download RBN data, and also how to become an RBN receiving node.

In an article by Ward Silver, N0AX, the American Radio Relay League has featured HamSCI in the August 2016 (Pages 68-71) issue of QST.  Ward's article discusses some history of amateur radio involvement in science, the vision of HamSCI, and a description of ham radio activities for the 2017 Total Solar Eclipse.

In addition, the August 2016 QST inlcudes a full-page profile of HamSCI member Magda Moses, KM4EGE (Page 13). Congratulations, Magda!
