Hi List,

Thirteen years ago SOHO caught these and ESA/NASA used the Subject title,
"Sun Bags Another Comet". Every few days it was updated and circulated on
astro related lists.

When I stopped observations around 2000 the Sun had "bagged" 102 on record.

They are magnanimously keen on showing how many thousand NEOs whiz past each
day (the fear factor at work again), yet I surmize from the posts that they
stopped counting or are not advising very frequently on the Sun's dietary
habits as in the past.

ESA did offer an awesome screensaver of SOHO images that updated live
every 15 minutes showing sunspots, CMEs, comets being bagged, etc. all thru
color-filtered masks. I tried to find it a couple of years ago, but it was
no longer offered. Perhaps..........

Best wishes,
Kiera
