Dear Argentine Astronomical Society,

In astronomy, even the most stable orbits occasionally face a bit of
"gravitational interference." Our usual editorial trajectory was slightly
diverted this month by the annual IAU Executive Committee meeting in
Lithuania. We apologize for the delay, but like a long-exposure photograph,
the wait has allowed several vital initiatives to come into clearer focus,
which deserve your kind attention.

The IAU cosmic calendar is moving quickly, starting with APRIM2026
