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.

MIT Haystack Observatory is pleased to announce the formal open source release of Digital RF version 2.5 under a BSD license. The software implements a data recording format for scientific radio frequency (RF) instrumentation using the HDF5 scientific data format. The implementation is designed for the management of highly time-dependent data from a large number of radio sensors. Applications include radio science (e.g., radio astronomy, geospace radar) and any project requiring the capture and use of RF data as raw digital samples.

The HamSCI team completed a successful weekend presenting at the 2017 Dayton Hamvention in Xenia, Ohio. From May 19-21, the HamSCI team ran a booth in the ARRL Expo area where they discussed the HamSCI mission, upcoming experiments, and ways ham radio operators could participate in HamSCI activities. The HamSCI team included members from the New Jersey Institute of TechnologyVirginia Tech, the MIT Haystack Observatory, and Citizen Scientists from the general amateur radio community. This includes the upcoming Solar Eclipse QSO Party (SEQP), participation in the EclipseMob Project, and a live demonstration of both Red Pitaya and Rabbit S-9C based Reverse Beacon Network receive nodes. On Saturday morning, HamSCI presented an ARRL-sponsored forum where members gave oral presentations about HamSCI research and activities. Photos, videos of the presentations, and PDFs of presentation slides are included in this post.

HamSCI member Bill Liles, NQ6Z, won the Best Paper Award at the 15th International Ionospheric Effects Symposium (IES2017) for his paper On the use of solar eclipses to study the ionosphereIES2017 was held in Alexandria, Virginia from May 9 - 11, 2017 and had the theme "Bridging the gap between applications and research involving ionospheric and space weather disciplines". Bill's paper includes a review of previous eclipse ionospheric findings and an overview of the efforts to study the August 21, 2017 Total Solar Eclipse. Bill's paper is co-authored with Cathryn Mitchell (M0IBG), Mark Cohen, Greg Earle (W4GDE), Nathaniel Frissell (W2NAF), K. Kirby-Patel, Laura Lukes (KK4FYT), Ethan Miller (K8GU), Magda Moses (KM4EGE), J. Nelson, and J. Rockway.
