Comet SWAN Sudden Brightening ! was created by Keith g
All, news has been circulating that Comet SWAN has undergone a sudden outburst, now at visual magnitude 4 - 4.5. It is believed that a fragment of the nucleus has separated from the main nucleus, and is quite impressive to view. Now if the rain will go away...Here's a short description from another list..
Keith..
Greetings:
At 0300-0330 UT today, I observed Comet Swan during twilight here on the
west coast.
It had brightened enormously. Perhaps mag 4. Certainly naked eye, just
wnw of the Hercules keystone.
During observation (18" Newt@63X), I saw what appeared to be a small
portion of the nucleus which had separated from the main nucleus. The
separated portion appeared at a position angle of ~45deg, if the comet's
tail is at position angle 180 degrees. The broken off piece was well
within the coma of the main object. I believe this may account for the
sudden and dramatic brightening.
All members are encouraged to continue observations in coming days, as
we have a great period of seeing in the next few days.
Could someone forward this to SFAA Announce?
Thanks,
Uncle Bob

Anyone manage to observe it? The weather here in Maynooth was not at all conducive to observing .... unless rain-drops are your target that is

no, weather here was horrible. Maybe tonight
the following is a report fromcloudy nights posted today
"I also had a chance to see it from a NELM6.8 dark sky yesterday. In short, this is the best comet (for northern hemisphere) since Ikeya-Zhang. It's prominent with the naked eye, even if I didn't know it was there, I'd notice it immediately! There is even a ~2 degree tail, visible with the naked eye at magnitude 3.9. I observed it in 7x50, 11x70 and 11x80 binoculars, plus a NexStar 11. Large, but very condensed, *BLUE* coma, prominent tail with streamers, the first 3 degrees really bright, but traceable for a little more than the *entire* FOV of the 7x50! For everyone who has not yet gone out to see it - go *now*, this is a spectacular comet!

Cloudy here so far. Any ayempt I have made with the 12" to find the comet has been met with in-promptu cloud when I thought it would be clear enough. I'm going to take the small 70mm scope with me tonight, then on the way home from work, if it is clear, I'll have a scout for it.

Success tonight in Celbridge.
Couldnt see it with binos but saw it in the view finder as a definate fuzzy blob when i goto it.
Spectacular!!!! and very bright indeed saw a hint of a tail but needed averted vision. clouds stayed away for long periods and how i wish i had a dark site.............
