BAA Journal news note on C/2019 Y4 (ATLAS) Nick James 04 May 2020 06:21 UTC
Morning all,

I thought I would share with you a news note that I have just prepared
for the next edition of the Journal of the BAA. It will probably be
edited for length and content prior to publication but I think it
demonstrates the amazing work that amateurs were able to do during the
recent fragmentation event. Many thanks to everyone who submitted
images, astrometry and photometry to the BAA over this period.

I also attach an animated GIF showing the images included in figure 5
run together as a movie. The sudden appearance of fragment A on April 9
and its subsequent drift down the tail is quite dramatic.

Keep observing this comet as it heads in to perihelion. Most large
professional telescopes are now unable to see it since the elongation is
small.

Nick.
