I simply had to share this report from Martin McKenna who
has dark rural Irish skies! Last night after most of our Comet Watches all
around Ireland were washed out by the storm, the clouds miraculously parted, at
least over Leinster and several of us got to see the Comet at its closest (about
2 degrees) to the Pleiades - an amazing sight in 10x50B with both tails visible,
even from the suburbs of Dublin. Unforgettable. Martin saw the Comet a few days
earlier and sent this report:
Hi David!
Observed comet Q2 Machholz on the night of 5/6.1.04 at 00.28
with the naked eye. Q2 was 5* below open cluster M45, a striking sight, the only
bright object in that area. After very good dark adaption i could make out the
ion tail as a beautiful neon blue streak pointing to the NE 5 degrees long to
the E of the Pleiades. The tail was broad as it left the coma and decreaed in
diameter with distance until it ended in a point. This was an incredible sight!
I reckoned that the tail would pass over or close to M45 in the days ahead,
todays image of the comet on www.spaceweather.com shows the ion tail touching
the reflection nebula around the star Merope. On 2 occasions i also suspected i
briefly glimpsed the dust tail as a thin grey streak to the SE. With the naked
eye the coma is large, grey,cirular and well condensed however through 10X50
binos it was a fantastic green, elongated and sporting lovely long blue
streamers at various position angles from the the central condensation. Comet is
a real treat, we are so lucky to see it high in the evening sky as it approaches
perihelion. Most bright comets stay close to the sun, visible only in the
twilight skirting the horizon leaving a short window for observation but this
guy is visible until the early hours of the morning giving many people time to
get a decent look. I was able to introduce a friend to the comet who has never
been interested in astronomy before, i told him to look below the 7 sisters and
he spotted the comet right away with the naked eye which amazed him, he
commented how people in the nearby passing cars had no idea that there was a new
visitor sitting in the sky so bright. This comet is a great way of getting new
people interested in astronomy. Mag:3.7 Dia:30' DC:6/ Ion tail 5* NE Dust tail
50' SE (16" Reflector) *Also seen a tumbling naked eye satellite pass in front
of the false nucleus!

Now, you don't have to have as much equipment or send in
as detailed a report but even if you see the comet with the naked eye do email
us at observe@astronomy.ie with your
name, location and a description in your own words so we can include
your sighting in our report.
Those of you who want to go further can read some notes I
put online about observing comets at:
If you see any other really nice ones please let me
know.
