On 7th August 2019, an impact flash lasting $\sim1$s was observed on Jupiter. The video of this event was analysed to obtain the lightcurve and determine the energy release and initial mass. We find that the impactor released a total energy of $96-151$ kilotons of TNT, corresponding to an initial mass between $190-260$ metric tonnes with a diameter between $4-10$m. We developed a fragmentation model to simulate the atmospheric breakup of the object and reproduce the lightcurve. We model three…

Analysis of the April 13, 2021 bolide off the coast of Florida and Grand Bahama Island
In this paper, we examine the trajectory, orbital, and radiometric characteristics of the bolide event occurring off the coast of southern Florida and the Grand Bahama Island on April 13, 2021. An
Detection of an Extremely Large Impact Flash on Jupiter by High-cadence Multiwavelength Observations
We report the detection of an optical impact flash on Jupiter on 2021 October 15 by a dedicated telescope, Planetary ObservatioN Camera for Optical Transient Surveys, for the first time. Our
Detection of a Bolide in Jupiter's Atmosphere With Juno UVS
The Ultraviolet Spectrograph (UVS) instrument on the Juno mission recorded transient bright emission from a point source in Jupiter's atmosphere. The spectrum shows that the emission is consistent
The Dynamical Viability of an Extended Jupiter Ring System
Planetary rings are often speculated as being a relatively common attribute of giant planets, partly based on their prevalence within the solar system. However, their formation and sustainability

The Impact of a Large Object on Jupiter in 2009 July
On 2009 July 19, we observed a single, large impact on Jupiter at a planetocentric latitude of 55°S. This and the Shoemaker-Levy 9 (SL9) impacts on Jupiter in 1994 are the only planetary-scale
Impact flux on Jupiter: From superbolides to large-scale collisions
Context. Regular observations of Jupiter by a large number of amateur astronomers have resulted in the serendipitous discovery of short bright flashes in its atmosphere, which have been proposed as
Small impacts on the giant planet Jupiter
Context. Video observations of Jupiter obtained by amateur astronomers over the past 8 years have shown five flashes of light with durations of 1–2 s, each observed by at least two observers that
NUMERICAL MODELING OF THE 2009 IMPACT EVENT ON JUPITER
We have investigated the 2009 July impact event on Jupiter using the ZEUS-MP 2 three-dimensional hydrodynamics code. We studied the impact itself and the following plume development. Eight impactors

First Earth-based Detection of a Superbolide on Jupiter
Cosmic collisions on planets cause detectable optical flashes that range from terrestrial shooting stars to bright fireballs. On 2010 June 3 a bolide in Jupiter's atmosphere was simultaneously
Long-Term Evolution of Comet SL-9 Impact Features: July 1994–September 1996
Abstract We present a two year study of the evolution of SL9 impact aerosol debris we observed between 0.4 and 0.9 micrometers with continuous high temporal coverage from July 1994 through September
Jupiter After the 2009 Impact: Hubble Space Telescope Imaging of the Impact-Generated Debris and Its Temporal Evolution
We report Hubble Space Telescope images of Jupiter during the aftermath of an impact by an unknown object in 2009 July. The 2009 impact-created debris field evolved more slowly than those created in
HST imaging of atmospheric phenomena created by the impact of comet Shoemaker-Levy 9
TLDR
Hubble Space Telescope (HST) images reveal major atmospheric changes created by the collision of comet Shoemaker-Levy 9 with Jupiter and record the overall change in Jupiter's appearance as a result of the bombardment.
