The EU-ESA Workshop on Size Determination of Potentially Hazardous Near-Earth Objects continues. For Tuesday, 11/12/24, we continued phase curves, but after that it was thermal infrared observations and polarimetry: https://indico.esa.int/event/530/contributions/ Absolute magnitudes and photometry from the MPC catalog Peter Vereš (Minor… Read More »Workshop: Size Determination of Potentially Hazardous NEOs pt.

Ongoing: the EU-ESA Workshop on Size Determination of Potentially Hazardous Near-Earth Objects (https://indico.esa.int/event/530). Step one in “Planetary Defense” is, of course, to spot the Potentially Hazardous Objects (PHOs). But step two is also important: gauge the size of the threat object.… Read More »Workshop: Size Determination of Potentially Hazardous NEOs
Talk about New Astronomy. In vol. 113 (Dec), we see some details on Aster, the first deep-space probe to come from INPE (the Brazilian space agency)! de Carvalho Assis Goulant, G. Statella, T. Sfair, R. Definition of multispectral camera system… Read More »Note, Paper: Bem-Vindo Brasileiros
Yes, an incoming impactor was detected before impact. Object 2024 UQ was spotted (by the ATLAS telescope system) and reported back to the NEOCP (the Minor Planet Center‘s Confirmation Page). A trajectory solution determined that the object was likely to… Read More »Pre-detection of Impacting Meteor 2024 UQ

And now for a little change of venue. With the obvious exception of “mini-moons” (TCOs and TCFs) asteroid targets are in heliocentric orbits, and often at ranges measured in AUs. Round-trip light time is a few minutes, and it’s unrealistic… Read More »Note, Paper: A-Robot
We’re in an era of infrared astronomy… because we never left. Hot off the ‘presses’ (well, server, actually) is a paper in Publications of the Astronomical Society of the Pacific to continue the field. The modern infrared age was marked… Read More »IRTF time, pt. 2- MIRSI me!
