“This week old region region 2736 (renumbered 2738) returns to Earth view, giving the solar flux a much needed boost. This means radio propagation returns to the high side of marginal for amateur, shortwave radio & emergency operators on Earth’s dayside. Luckily, this monster region is not a threat for big flares or radio blackouts so GPS users should continue to enjoy decent reception, especially on Earth’s dayside.
Aurora photographers at high latitudes also get another brief chance for aurora views this week due to another small pocket of fast solar wind expected around April 12-13. On top of that, we have had some very strange lights in the sky recently due to a NASA rocket mission to study aurora (called AZURE). Learn the details of these stories, what conditions to expect and what else our Sun has in store this week.”
