2017 Total Solar Eclipse

Map of US Eclipses from 2017-2052

On 21 August 2017, a total solar eclipse will cause the shadow of the moon to traverse the United States from Oregon to South Carolina in just over 90 minutes. Although the ionospheric effects of solar eclipses have been studied for over 50 years, many unanswered questions remain. HamSCI is inviting amateur radio operators to participate in a large-scale experiment which will characterize the ionospheric response to the total solar eclipse and target open science questions.

How can hams and the general public get involved?

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.
