A Tail of Two Comets

   April 1990 Comet Austin (1989c1) now getting brighter approaching naked-eye visibility.
   April 2020 Comet ATLAS (2019c1) predicted to brighten to naked eye visibility has now apparently broken apart.

   30 years ago, April 1990, I wrote the first of what was to become a continuing column about Earth and Space called Scope on the Skies for Science Scope Magazine. This is the Professional Journal for Middle School Science Teachers and is published by the National Science Teaching Association (NSTA)

   That April 1990 column, Comet Watch – “Comet Austin”, was about a potential naked-eye visible comet discovered by New Zealand Astronomer Rod Austin during December 1989. The comet was appropriately named Comet Austin 1989c1. The comet increased in brightness over the months following its discovery reaching around 4th magnitude and naked-eye visibility the following May of 1990.

   This month as Comet ATLAS (2019c1) was showing signs of becoming a bright comet it broke apart. This was reported a few days ago and the break-up has since been tentatively confirmed.
