Space Weather Update: Welcome GOES-16!

Sharp eyes might have noticed a very abrupt drop on the solar X-rays graph today. What happened to the Sun? It went into cardiac arrest? Nope. Today, December 9, the NOAA SWPC has switched to GOES-16 as the primary satellite for geostationary space weather observations. GOES-16 was launched on 19 November 2016 and is the […]

Space Weather Update: Official Solar Cycle 25 Forecast Update

The NOAA/NASA Solar Cycle prediction panel has issued an official statement yesterday with news about the upcoming Solar Cycle 25. The most notable bit of information is that we likely haven’t passed solar minimum yet. The panel predicts solar minimum to occur in April, 2020 with an uncertainty range of +/- 6 months. The panel […]

Space Weather Update: Coronal hole faces Earth

A small but interesting southern hemisphere coronal hole is facing our planet today. While this coronal hole is fairly small, a quick look at the solar wind data from STEREO Ahead shows us some surprising numbers. The solar wind stream from this coronal hole arrived at STEREO Ahead late on 20 August and pushed the total strength […]

via the ARRL: HAARP Facility to Resume Ionospheric Research this Week

Alaska’s super-power High-Frequency Active Auroral Research Program (HAARP) transmitters in Gakona, Alaska, will fire up again for the spring research campaign April 6 – 14. University of Alaska Fairbanks (UAF) Space Physics Group researcher and HAARP Chief Scientist Chris Fallen, KL3WX, told ARRL that more than 40 hours of “externally funded” experiments are in the […]

Scientists in Alaska Attempt to Produce Artificial Aurora

Sometimes, experiments don’t work out as planned. In late September, Christopher Fallen and technicians at the High Frequency Active Auroral Research Program (HAARP) near Gakona, Alaska, switched on a giant array of 180 antennas. They were hoping to produce radio-induced airglow, also known as artificial aurora, as a way to better understand the mechanics of […]

Amateur Radio Participation is Key to University Solar Eclipse Experiment

Virginia Tech electrical engineering professor Greg Earle, W4GDE, is heading up a National Science Foundation (NSF)-funded solar eclipse experiment dubbed CEDAR — Coupling, Energetics, and Dynamics of Atmospheric Regions. The experiment proposes to study the effects on the ionosphere of the August 21 total eclipse of the sun, using a combination of GPS receivers, the […]

via the ARRL: Moderate (G2) Geomagnetic Storm Watch Issued for August 4

NOAA’s Space Weather Prediction Center (SWPC) has issued a G2 (moderate) geomagnetic storm watch for August 4, and a G1 (minor) watch for August 5. “A coronal hole high-speed stream, originating from a recurrent, positive polarity coronal hole…is likely to cause geomagnetic storming at the G2 level on 4 August 2017, and at the G1 […]
