Aurora-Chasing Citizen Scientists Help Discover A New Feature of STEVE

The plucky subauroral phenomenon STEVE (Strong Thermal Emission Velocity Enhancement) has struck again! Teamwork between citizen scientists and scientists Joshua Semeter, Michael Hunnekuhl, Elizabeth MacDonald, Michael Hirsch, Neil Zeller, Alexei Chernenkoff, and Jun Wang, has led to new information and new mysteries about features in STEVE’s dapper green picket fence structure. The team’s work—which includes[…]

LIstening and Learning Recap

After our first anti-racism meeting in support of #Strike4BlackLives, the Aurorasaurus team has been holding monthly meetings alongside members of the aurora science and citizen science communities on further action items to hold ourselves accountable. If you are interested in joining us for future meetings, please let us know at aurorasaurus.info@gmail.com. In this post, Liz[…]

Laura Learns Aurora: The Buzz on Bz

Laura here! I am an aurora enthusiast, but new to the science side. Fortunately, the Aurorasaurus blog and website are full of great resources that I’ll be sharing out as I cultivate my knowledge.  This week: what is Bz (pronounced “bee-zee”)? It sounds complicated but this post by former intern Sean McCloat makes it clearer.[…]

Sharing the story: Aurorasaurus Intern Vince

My backstory with the Aurora and Aurorasaurus The moment I saw my first aurora is forever ingrained in my memory.  The Halloween Storms of 2003 left the night skies above my Minnesota house dancing with green and purple lights, and seeing them at four years old as I walked down my neighborhood street, trick-or-treating with[…]

An animation shows how the center slices of each moment in a moving all-sky camera are placed next to each other to create a keogram

Eyes on the Aurora, Part 2: What is a Keogram?

Guest post by Aurorasaurus Ambassador Jeremy Kuzub This article is the second of three about how researchers and citizen scientists record and explore years of auroral activity using all-sky cameras, keograms, and software visualizations. The first post is available here.  Looking Up The first step in aurora borealis research is just looking up at the night[…]

A Frenzy of Sky Phenomena: Reflections on a Once-in-a-Lifetime Chase

In the early morning hours of July 13, a slow-moving coronal mass ejection from the Sun arrived early on its journey to Earth. That afternoon, word spread across social media in Europe, Canada, and the US: there might be aurora tonight. No one knew, however, whether it would last long enough for this part of Earth[…]

Another Lively Season of Night-Shining Clouds

by Kasha Patel Reposted from NASA Earth Observatory  Every summer in the Northern Hemisphere, electric blue streaks form high in the atmosphere. These seasonal clouds typically lurk about 80 kilometers (50 miles) overhead in the mesosphere around the Arctic, but every once in a while they form at lower latitudes. In 2019, the clouds showed up in places where[…]

Over an outlined map of North America are superimposed multiple all-sky image animations, showing the cameras' coverage across the continent under the auroral oval

Eyes on the Aurora Part 1: What is an All-Sky Camera?

Guest post by Aurorasaurus Ambassador Jeremy Kuzub This article is the first of three about how researchers and citizen scientists record and explore years of auroral activity using all-sky cameras, keograms, and software visualizations. What if you could stand under the aurora-filled night sky and watch everything from horizon to horizon, all night, every night,[…]

Calling Out and Calling In

A message from our founder, Dr. Liz MacDonald On June 10, 2020, there was an organized event to shut down STEM (Science, Technology, Engineering, and Mathematics) in support of Black Lives Matter. Aurorasaurus participated with a day of reflective practice alongside members of our community and the scientific community (agenda pasted below). We stand firmly[…]
