Take a look at this image from the SOHO LASKO 2 camera. A sun grazing comet just below the sun.

There's a form to report them (http://sungrazer.nrl.navy.mil/?p=cometform).

I can't find any report on it and sometimes the images are the result of artifact. I await an update on this. Could be exciting.

Go to the SOHO movie theater page at http://sohodata.nascom.nasa.gov/cgi-bin/soho_movie_theater
and create a movie with the LASCO 2 images from May 11-12. Object enters the field of view just below the 00 seconds in the date stamp. Its fairly bright but fades and is barely visible when it passes behind the occulting mask. There is no sign of it emerging from behind the mask. Most likely, a very small nucleus that was completly vaporize when it got too close to the Sun. I couldn't get the report form the work for me, so I sent the Sungrazer section an old fashioned E-mail.

Ya, I am wondering that too.

You can see the thing midway through this MPEG movie. (http://sohowww.nascom.nasa.gov/data/LATEST/current_c2small.mpg) For whatever reason I have to click on the link then refresh the page to get it to work.

It has to have been noticed.

Could it have been this known comet? From Spaceweather.com today:
DISCONNECTION EVENT IN THE TAIL OF COMET LEMMON: Comet Lemmon (C/2012 F6), which is receding from the sun not far beyond the orbit of Earth, has just experienced a "disconnection event." A cloud of dusty plasma is propagating down the comet's tail, shown here in a photo taken by amateur astronomer Paul Mortfield on May 15th:The image (http://spaceweather.com/gallery/indiv_upload.php?upload_id=81856)
