The Gannon Storm: Citizen science observations during the geomagnetic superstorm of 10 May 2024
Maxime Grandin, Emma Bruus, Vincent E. Ledvina +12
The 10 May 2024 geomagnetic storm, referred to as the Gannon Storm in this paper, was one of the most extreme to have occurred in over 20 years. In the era of smartphones and socia…
Observations of the 2023 February 27 fireball in northern Sweden using the auroral imaging system ALIS_4D
Gabriel Borderes-Motta, Daniel Kastinen, Tima Sergienko +7
On 2023 February 27 at 18:15:55.77 UT, a bright fireball streaked across the sky above northern Sweden. The event offered a valuable opportunity to study the phenomenon using an op…
Long-term outburst activity of comet 17P/Holmes and constraints on ejecta size distributions
Maria Gritsevich, Marcin Wesołowski, Josep M. Trigo-Rodríguez +4
A quantitative understanding of cometary outbursts requires robust constraints on the size distribution of ejected particles, which governs outburst dynamics and underpins estimate…
Distance-Independent Atmospheric Refraction Correction for Accurate Retrieval of Fireball Trajectories
Jaakko Visuri, Maria Gritsevich, Janne Sievinen
Accurate determination of fireball direction is essential for retrieving trajectories and velocities. Errors in these measurements have significant implications, affecting the calc…
The Fireball of November 24, 1970, as the Most Probable Source of the Ischgl Meteorite
Maria Gritsevich, Jarmo Moilanen, Jaakko Visuri +13
In June 1976, a pristine meteorite stone weighing approximately 1 kg, fully covered with a fresh black fusion crust, was collected on a mountain road in the high-altitude Alpine en…
Oort cloud perturbations as a source of hyperbolic Earth impactors
Eloy Peña-Asensio, Jaakko Visuri, Josep M. Trigo-Rodríguez +4
The observation of interstellar objects 1I/'Oumuamua and 2I/Borisov suggests the existence of a larger population of smaller projectiles that impact our planet with unbound orbits.…
Evolution of the Dust Trail of Comet 17P/Holmes
Maria Gritsevich, Markku Nissinen, Arto Oksanen +2
The massive outburst of the comet 17P/Holmes in October 2007 is the largest known outburst by a comet thus far. We present a new comprehensive model describing the evolution of the…
The impact and recovery of asteroid 2018 LA
Peter Jenniskens, Mohutsiwa Gabadirwe, Qing-Zhu Yin +63
The June 2, 2018, impact of asteroid 2018 LA over Botswana is only the second asteroid detected in space prior to impacting over land. Here, we report on the successful recovery of…
