COMET
LULIN BRIGHTENS--VISUAL REPORTS: "Today,
Feb. 17th at 4 am, I observed the comet with my 3.5-inch refractor,"
reports Mariano Ribas of Buenos Aires, Argentina.
"It is much brighter than it was just a few nights ago. I
estimate the magnitude at +5.6. If this brightening continues,
Lulin could reach magnitude +5.0 or even brighter during its closest
approach next week."
"I
observed comet Lulin before dawn this morning, Feb. 17th, and
I found it in an instant using 10x50 binoculars," says Martin
Mc Kenna of Maghera, N. Ireland. "The comet was
very bright and large with a coma 20 arcminutes in diameter. Despite
the glare of the last quarter Moon, I was very impressed to see
the comet easily with the naked eye with even a hint of green
colour. From a dark country site, Lulin should be an easy naked-eye
object, a view which can only get better at close approach to
Earth."
"Lulin
is bright and it is moving fast!" adds Fredrik Broms
of Kvaløya, Norway. "On Feb. 17th the comet was easily
detected in a simple pair of 8x42 binoculars, and with a bit of
patience it could just be made out with the naked eye. The comet
moved a noticable amount during my 4-hour observing session."

Comet
Lulin is brightening and moving faster across the sky. The
anti-tail seems quite a bit brighter than the ion tail and
has a distinctly reddish hue. |

Lulin
has brightened so much, telescopic amplification is no longer
needed to photograph it. Using an off-the-shelf digital
camera, Alex Roca of Hortoneda, Spain, caught the comet
passing 4th-magnitude star theta Virginis on Feb. 17th.
"I mounted the camera, a Nikon
D40, on the back of my telescope to track the stars,"
he says. "Otherwise, the telescope played no part in
this 10 minute exposure."
