March edition of Cometary Science News (apparently no Feb?) now up. Three papers: luminescence of objects (i. e., UV/IR reemission) including asteroids, and distant-yet-active comets. Luminescence is chemically/compositionally interesting, but for characterization, not search. The Hui et al. paper on distant comets includes a review (so far…) of such comets (indicating activity from supervolatiles).
