From the Editors
It has been an eventful year! We invite you to pour yourself a hot beverage - or throw some shrimp on the barbie, if that's what you're into - and curl up with this holiday edition of the FRB Newsletter. We're excited to see what new surprises await the FRB world in 2025.

Algorithms, Instrumentation, and Data Access
- Mapping the ionosphere with millions of phones; Smith et al., Nature, DOI: 10.1038/s41586-024-08072-x
"...a distributed network of noisy sensors - in the form of millions of Android phones - can double the measurement coverage, providing an accurate picture of the ionosphere in areas of the world underserved by conventional infrastructure. Using smartphone measurements, we resolve features such as plasma bubbles over India and South America, solar-storm-enhanced density over North America and a mid-latitude ionospheric trough over Europe."

ECR Journal Club:
The FRB Early Career Researcher Journal Club would like to extend an invitation to join our bi-weekly, informal meetings. The journal club is open to anyone at the undergraduate, graduate/PhD, or postdoc career stage. Meetings are one hour long and consist of a paper presentation followed by open discussion. From personal experience, this has been a wonderful forum to learn from and get to know other FRB early career researchers in a low-stakes, friendly environment! We will send out a poll to determine new meeting times in January with meetings starting up again in February. If you'd like to join, please reach out to any of the organizers for more information:
- Alexa Gordon - alexagordon2026[at]u.northwestern.edu
- Alice Curtin - alice.curtin[at]mail.mcgill.ca
- Yuxin (Vic) Dong - yuxin.dong[at]northwestern.edu
- Sunil Simha - sunilsimha.hassansatish[at]northwestern.edu
