SOLAR WIND, INCOMING: A stream of high-speed solar wind is expected to reach Earth on Feb. 15th or 16th, possibly causing G1-class geomagnetic storms. The gaseous material is flowing from a hole in the sun's atmosphere now turning toward our planet:
This extreme ultraviolet image of the sun was taken by NASA's Solar Dynamics Observatory
This is a coronal hole, a region where the sun's magnetic field opens up and allows solar wind to escape. Solar wind emerging faster than 550 km/s (1.2 million mph) is approaching Earth in a stream broad enough to envelop our planet for at least two days. Arctic sky watchers should be alert for auroras after Valentine's Day. Free: Aurora Alerts
STARMAN, 1 MILLION KILOMETERS AWAY: On Feb. 10, 2018, Enrico Pettarin of Farra dIsonzo, Italy, photographed Elon Musk's cherry red Tesla Roadster more than 1 million km from Earth "It was very faint," says Pettarin, "shining in reflected sunlight like a 17th magnitude star, but I was able to photograph it using my 0.4-meter telescope."
Launched on Feb. 6, 2018, by a Falcon Heavy Rocket at Cape Canaveral, the Roadster is traveling around the sun on an elliptical orbit that will take it beyond the orbit of Mars. Every day it is getting farther from Earth.
Other amateur astronomers around the world have also been photographing the distant electric car, piloted by a space-suited mannequin named "Starman." At the moment, Pettarin holds the distance record. But stay tuned, because records are meant to be broken!

VALENTINE'S DAY IS COMING: Nothing says "I Love You" like a Valentine's pendant from the edge of space. 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:
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.
