The Younger Dryas (YD) cosmic impact hypothesis is gaining support due to the increasing amount of proxy evidence from 26 Younger Dryas Boundary sites that includes depositions of magnetic, silicate, and carbon spherules; high‐temperature meltglass and melt accretions; nanodiamonds, and Ir and Pt deposits, as well as evidence of major biomass burning and widespread extinctions in stratigraphic layers dated ∼12.8 kyr ago. Among the possible causes, an encounter with a swarm of fragments on an orbit similar to that of 2P/Encke is proposed. This work suggests another potential source of impacting material that requires no special events in the Solar System: Main Belt asteroids excited into highly eccentric Earth‐crossing orbits via mean‐motion resonance with Jupiter and the ν6 secular resonance with Saturn—the established mechanisms of Main Asteroid Belt depletion and Earth‐bound meteorite delivery. It is shown that the probability of and the time between collisions of ejected material with Earth (Δt ∼ 32 kyr), as well as the energy of impacts, are broadly compatible with the YD impact proxy evidence. Such events may reoccur via bombardments of fragment swarms, potentially challenging existing asteroid deflection concepts.

During the British Astronomical Association (BAA) 2022 campaign, 27436 photometric observations of the dwarf nova (DN) CG Draconis were made, with 106 eclipses recorded. This work summarizes the new data available and provides updated ephemeris and commentary on the observed eclipse profiles. The orbital period found is = 4 h 31 m 38 s ± 1 s . Two types of quasi-periodic outbursts are identified: normal outbursts, of Δ ≈ 1.25 mag amplitude, and bright, of Δ ≈ 1.5 mag. The pattern resembles superoutbursts of SU UMa-type DNe, however, no presence of superhumps characterizing these DNe was found. Given CG Dra is located above the period gap, it may represent a new intermediary subtype between SS Cyg and SU UMa-type stars, or provide support to superoutburst models that do not rely on eccentric accretion disks.
