“…Aperture photometry of the binary system was performed using the BOOTES-1 telescope. The Burst Observer and Optical Transient Exploring System (BOOTES) is a worldwide robotic telescope network primarily designed to detect and follow gamma-ray bursts (Castro-Tirado et al 2012;Hu et al 2023). The aperture photometry measurements were performed using BOOTES-1, which is a 0.3 m aperture telescope located in the Estación de Sondeos Atmosféricos in the Centro de Experimentación, El Arenosillo, Huelva, Spain.…”

The NASA Double Asteroid Redirection Test (DART) spacecraft successfully crashed on Dimorphos, the secondary component of the binary (65803) Didymos system. Following the impact, a large dust cloud was released, and a long-lasting dust tail developed. We have extensively monitored the dust tail from the ground and the Hubble Space Telescope. We provide a characterization of the ejecta dust properties, i.e., particle size distribution and ejection speeds, ejection geometric parameters, and mass, by combining both observational data sets and using Monte Carlo models of the observed dust tail. The size distribution function that best fits the imaging data is a broken power law having a power index of –2.5 for particles of r ≤ 3 mm and –3.7 for larger particles. The particles range in size from 1 μm up to 5 cm. The ejecta is characterized by two components, depending on velocity and ejection direction. The northern component of the double tail, observed since 2022 October 8, might be associated with a secondary ejection event from impacting debris on Didymos, although is also possible that this feature results from the binary system dynamics alone. The lower limit to the total dust mass ejected is estimated at ∼6 × 106 kg, half of this mass being ejected to interplanetary space.

The status of the Boyden observatory and equipment will be evaluated for use in optical counterpart studies of high energy sources. Optical systems include the 1.5 m Boyden telescope which has recently received system and equipment upgrades to the photometer, specifically a new sCMOS camera system. Additionally a state of the art spectro-polarimeter has been commissioned and is in final testing and initial observing phases. Besides the 1.5 m telescope, there is also robotic telescope systems, e.g. Watcher and BOOTES-6. Watcher, was primarily for follow-up of gamma ray bursts, but has also been used for optical counterpart and survey studies, and target-ofopportunity events. BOOTES-6, or Burst Observer and Optical Transient Exploring System, is a new telescope system that allows for much faster target acquisition for Gamma-ray bursts events, but is also available for optical studies of transient phenomena or optical counterpart studies. With these optical systems, various multi-wavelength studies and collaborative efforts are envisioned for the Observatory

“…In order to gather extensive data on the orbits of solar system small bodies and fireball trajectories and their behaviors, photographic all-sky camera networks have been established worldwide since the mid-20th century (Bland et al, 2012;Ceplecha & Rajchl, 1965;Colas et al, 2020;Devillepoix et al, 2020;Halliday et al, 1978;Howie et al, 2017;Trigo-Rodrıǵuez et al, 2006;Whipple, 1938). Subsequently, a posibility of meteor detection has been discussed or even integrated also within the broader scoped surveys on the Earth and beyond including the Vera C. Rubin Observatory, previously referred to as the Large Synoptic Survey Telescope (LSST), Mini-EUSO telescope on board the ISS, high-power large-aperture (HPLA) radars such as the European Incoherent Scatter facility EISCAT, the global network of robotic astronomical observatories BOOTES, and EnVision mission to Venus developed by the European Space Agency (Bektešević et al, 2018;Castro-Tirado, 2023;Christou & Gritsevich, 2024;Coleman et al, 2023;Hu et al, 2023;Kero et al, 2019;Pellinen-Wannberg et al, 1998;Räbinä et al, 2016;Vinković et al, 2016;Vinković & Gritsevich, 2020). Of particular interest are relatively rare meteorite-producing events (Boaca et al, 2022;Brown et al, 2013;Gritsevich, 2008a;Peña-Asensio et al, 2023;Sansom, Gritsevich, et al, 2019;Wetherill & ReVelle, 1981), as their identification and subsequent analysis may allow rapid recovery of unique extraterrestrial samples in unweathered conditions while also providing clues to their dynamic origin (Dmitriev et al, 2015;Jansen-Sturgeon et al, 2019;Kyrylenko et al, 2023;Peña-Asensio et al, 2021;Trigo-Rodrıǵuez et al, 2015).…”

The discovery of the Ischgl meteorite unfolded in a captivating manner. 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 environment. The recovery took place while clearing the remnants of a snow avalanche, 2 km northwest of the town of Ischgl in Austria. Subsequent to its retrieval, the specimen remained tucked away in the finder's private residence without undergoing any scientific examination or identification until 2008, when it was brought to the University of Innsbruck. Upon evaluation, the sample was classified as a well‐preserved LL6 chondrite, with a W0 weathering grade, implying a relatively short time between the meteorite fall and its retrieval. To investigate the potential connection between the Ischgl meteorite and a recorded fireball event, we have reviewed all documented fireballs ever photographed by German fireball camera stations. This examination led us to identify the fireball EN241170 observed in Germany by 10 different European Network stations on the night of November 23/24, 1970, as the most likely candidate. We employed state‐of‐the‐art techniques to reconstruct the fireball's trajectory and to reproduce both its luminous and dark flight phases in detail. We find that the determined strewn field and the generated heat map closely align with the recovery location of the Ischgl meteorite. Furthermore, the measured radionuclide data reported here indicate that the pre‐atmospheric size of the Ischgl meteoroid is consistent with the mass estimate inferred from our deceleration analysis along the trajectory. Our findings strongly support the conclusion that the Ischgl meteorite originated from the EN241170 fireball, effectively establishing it as a confirmed meteorite fall. This discovery enables to determine, along with the physical properties, also the heliocentric orbit and cosmic history of the Ischgl meteorite.
