GEOMAGNETIC UNREST: Earth is entering a stream of solar wind flowing from a hole in the sun's atmosphere. This is causing geomagnetic unrest around the poles. High-latitude sky watchers should be alert for auroras on July 21st, especially in the southern hemisphere where winter darkness favors visibility. Free: Aurora Alerts
CME SWEEPS ASIDE COSMIC RAYS: On July 16th, a CME hit Earth's magnetic field, sparking two days of geomagnetic storms and beautiful southernauroras. The solar storm cloud also swept aside some of the cosmic rays currently surrounding Earth. Spaceweather.com and the students of Earth to Sky Calculus launched a space weather balloon to the stratosphere hours after the CME arrived. We detected a 7% decrease in X-rays and gamma-rays (two tracers of secondary cosmic rays). Neutron monitors in the Arctic and Antarctic recorded similar decrements. For instance, these data from the Bartol Research Institute show a nearly 8% drop in cosmic ray neutrons reaching the South Pole:
This is called a "Forbush Decrease," named after physicist Scott E. Forbush who first described it in the 20th century. Wherever CMEs go, cosmic rays are deflected by magnetic fields inside the solar storm clouds. As a result, when solar activity is high, cosmic radiation around Earth is relatively low--a yin-yang relationship that holds throughout all phases of the solar cycle.
Lately, cosmic rays around Earth have been intensifying as the solar cycle plunges toward minimum. The CME of July 16th reversed that trend--but only for a few days. Solar activity has returned to low levels and cosmic rays are on the rise again.
Why do we care about cosmic rays? For one thing, they penetrate commercial airlines, dosing passengers and flight crews so much that pilots are classified as occupational radiation workers. Some research shows that cosmic rays can seed clouds and trigger lightning, potentially altering weather and climate. Furthermore, there are studies ( #1, #2, #3, #4) linking cosmic rays with cardiac arrhythmias in the general population.
ICASA Licensing Matters - The SARL is aware of members who are having trouble in resolving their various licensing issues, especially in the case of a cancelled licence.

A completed ICASA Application Form
A copy of their Identity Document
Proof of payment for the re-application fee.
Original RAE results or HAREC certificate
In the case where a member has paid for a multiple year licence (2 years to 5 years) and has only received a one-year licence, the following information must be provided:
A copy of their communication/s with ICASA.
A copy of the payment made for a multiple year licence.
firstname.lastname@example.org. Use your call sign and licence number as a topic in the e-mail.

Interview with the IARU President - International Amateur Radio Union IARU) president Tim Ellam, VE6SH, talks with ARRL Media and Public Relations Manager Sean Kutzko, KX9X, at Hamvention 2017. Tim explains what the IARU is, how IARU's work affects every radio amateur in the world, and why hams should pay attention to the events within their own IARU member society.

SARL Fund for Disaster Victims
I am pleased to announce that Council have decided, on short notice, to establish an independent General Disaster Trust Fund to assist fellow radio amateurs who have suffered because of natural disasters. In a nutshell, this general disaster fund will be administered by independent trustees and not by Council.

NVIS PROPAGATION - UNDERSTAND THE BASICS - Radio Communication via Near Vertical Incidence Skywave propagation can be used for communication over a wide area. It is very well suited for emergency communication. It uses frequencies between 3 and 10 MHz with amateur allocation in the 5 MHz particularly attractive. Two propagation researchers, Ben Witvliet and Rosa Ma Alsina-Pages wrote an interesting paper with lots of reference to other papers for additional reading.
