GEOMAGNETIC STORM PREDICTED: NOAA forecasters say there is a 65% chance of G1-class geomagnetic storms on Feb. 26th when a stream of solar wind is expected to hit Earth. The gaseous material is flowing from an equator-stradding hole in the sun's atmosphere:
This is a coronal hole--a region where the sun's magnetic field opens up and allows solar wind to escape. In this case, the wind is blowing faster than 600 km/s (1.3 million mph). Earth should be inside the stream for approximately two days.
G1-class storms are relatively minor and have litte effect on satellites or global power grids. However, they can spark bright auroras around the Arctic Circle and confuse animals that use magnetism to navigate at high latitudes. Stay tuned for updates as the solar wind stream approaches.

RARE HAWAIIAN LIGHT PILLAR: Frankie Lucena of Puerto Rico frequently scans the automated Gemini webcam on Hawaii's Mauna Kea volcano, looking for sprites and other forms of exotic lightning. On Feb. 13th he saw something--but it wasn't lightning. "It was a rare Hawaiian light pillar," he says. Here is one frame from the complete video:
"I was searching for thunderstorms and just happened to come across this rarely seen event in this part of the world," says Lucena. "Light pillars usually occur in cold climates like Canada so to see them this far south is unusual."
Light pillars appear when urban lights reflect from the flat faces of ice crystals fluttering down from high freezing clouds. The source of the crystals, in this case, was probably a bank of altostratus/cumulus clouds shown in the video. "I do not recall seeing examples of these pillars so far south or in a location like Hawaii," says atmospheric optics expert Les Cowley. "So these are very rare indeed."

CROWD-FUNDING SPACE WEATHER RESEARCH: Did you know that cosmic rays in Earth's atmosphere are intensifying? It's true, and we are monitoring the phenomenon with regular space weather balloon flights to the stratosphere. This student science program is not supported by any government grant or corporate sponsorship. Instead, we raise our research funds by selling these:
On Dec. 31, 2017, the students of Earth to Sky Calculus flew a payload-full of these heart-shaped pendants to the stratosphere, 35.1 km (115,158 feet) above Earth's surface. They make great birthday and Mother's Day gifts.
You can have one for $119.95. Each glittering pendant comes with a greeting card showing the jewelry in flight and telling the story of its journey to the edge of space. Sales of this pendant support the Earth to Sky Calculus cosmic ray ballooning program and hands-on STEM research.
