    Here's a list of meteor showers due in 2012. All in all the viewing conditions will be very favourable as regards interference from moonlight. Now if we could just guarnantee cloudless nights... Anyway update your calendars with the dates. Copied from EarthSky.com

    January 4
    , 2012 in the wee hours before dawn Quadrantids
    When we say January 4, we mean in the wee hours before dawn, not that night. Although the waxing gibbous moon lights up most of the
    night and doesn’t set until roughly 3 a.m. local time, this is about the best time of night to watch for these meteors.
    Although the Quadrantids can produce over 100 meteors per hour, the sharp peak only lasts for a few hours.

    April 22, 2012 Lyrids
    The Lyrid meteors – April’s “shooting stars” – tend to be bright and often leave trails.
    About 10-20 meteors per hour at peak can be expected. Plus, the Lyrids are known for uncommon surges that can sometimes bring
    the rate up to 100 per hour. Those rare outbursts are not easy to predict, but they’re one of the reasons the tantalizing Lyrids
    are worth checking out. The radiant for this shower is in the constellation Lyra, which rises in the northeast at about 10 p.m.
    Fortunately, in 2012, the new moon guarantees a dark sky in the late night and morning hours, the best time to watch the Lyrid shower.
    As a general rule, the greatest number of Lyrid meteors fall in the dark hours before dawn. The optimal night will probably be from
    late night April 21 until dawn April 22, though the night before or after (April 21/22 and April 22/23) may also offer a sprinkling
    of Lyrid meteors. With no moon to obscure this year’s display, we are assured of dark skies for the 2012 Lyrid meteor shower!

    May 5 and 6, 2012 Eta Aquarids
    This shower has a relatively broad maximum but is expected to show the greatest number of meteors before dawn on May 5 or 6.
    Unfortunately, the closest and largest full moon of the year will be out all night long, leaving no dark sky for this year’s
    Eta Aquarid show. But die-hard meteor enthusiasts will be watching anyway, to see how many Lyrids can be seen in a moonlit sky.
    At northerly latitudes the meteor numbers are few and far between, 10 to 20 meteors per hour may be visible in a dark sky.
    Farther south – like in the Southern Hemisphere – the meteor numbers increase dramatically, perhaps two to three times more
    Eta Aquarid meteors streaking the southern skies. For the most part, this is a predawn shower. The radiant for this shower appears
    in the east-southeast at about 4 a.m. and the hour or two before dawn offers the most meteors.
    The broad peak to this shower means that some meteors may fly in the dark hour before dawn for a few days before and after
    the predicted optimal date. Although the most meteors will probably rain down on May 5 or 6 before dawn, the full moon is sure
    to wash away all but the brightest Eta Aquarid meteors.

    July 28 and 29, 2012 Delta Aquarids
    Like the Eta Aquarids, this shower favors the Southern Hemisphere, and the tropical latitudes in the Northern Hemisphere.
    Although the waxing gibbous moon won’t set till after midnight, the hours between moonset and dawn will probably offer the most
    Delta Aquarid meteors. The meteors appear to radiate from the southern part of the sky. From northern temperate latitudes,
    the maximum hourly rate may reach 15-20 meteors in a dark sky. Unlike many meteor showers, this one doesn’t have a very definite peak,
    despite the dates given above. Instead, these medium-speed meteors ramble along fairly steadily throughout late July and early August.
    An hour or two before dawn usually presents the most favorable view of the Delta Aquarids. Try watching in late July, in the
    hours between moonset and dawn.

    August 12 and 13, 2012 Perseids
    And when we say August 12 or 13, we mean the morning hours after midnight – not that night. The waning crescent moon will rise
    around midnight, only somewhat obscuring the Perseid display during the shower’s actual peak. The moonlight shouldn’t be so
    overwhelming as to ruin the show. These typically fast and bright meteors radiate from a point in the constellation Perseus the Hero.
    You don’t need to know Perseus to watch the shower because the meteors appear in all parts of the sky. The Perseids are considered
    by many people to be the year’s best shower, and often peak at 50 or more meteors per hour in a dark sky. The Perseids tend to
    strengthen in number as late night deepens into midnight, and typically produce the most meteors in the wee hours before dawn.
    These meteors are often bright and frequently leave persistent trains. Starting at mid to late evening on the nights of August 11/12
    and 12/13, watch for the Perseid meteors to streak across this short summer night from late night until dawn, with only a little
    interference from the waning crescent moon.

    October 7, 2012 Draconids
    The radiant point for the Draconid meteor shower almost coincides with the head of the constellation Draco the Dragon in the
    northern sky. That’s why the Draconids are best viewed from the Northern Hemisphere. The Draconid shower is a real oddity, in that
    the radiant point stands highest in the sky as darkness falls. Unlike many meteor showers, the Draconids are more likely to fly in
    the evening hours than in the morning hours after midnight. This shower is usually a sleeper, producing only a handful of languid
    meteors per hour in most years. But watch out if the Dragon awakes! In rare instances, fiery Draco has been known to spew forth many
    hundreds of meteors in a single hour. With no moon to interfere during the evening hours, try watching at nightfall and early evening
    on October 7 and 8.

    October 21, 2012, before dawn. Orionids
    With the waxing crescent moon setting before midnight (on October 20), that means a dark sky between midnight and dawn, or during
    the best viewing hours for the Orionid meteors. On a dark, moonless night, the Orionids exhibit a maximum of about 15 meteors per
    hour. These fast-moving meteors occasionally leave persistent trains and bright fireballs. If you trace these meteors backward, they
    seem to come from the Club of the famous constellation Orion the Hunter. You might know Orion’s bright, ruddy star Betelgeuse.
    The radiant is north of Betelgeuse. The Orionids have a broad and irregular peak that isn’t easy to predict. More meteors tend to
    fly after midnight, and the Orionids are typically at their best in the wee hours before dawn. The best viewing for the Orionids in
    2012 will probably be before dawn on October 21..

    November 4/5, 2012, late night November 4 until dawn November 5 South Taurids
    The South (and North) Taurids are perhaps best suited to die-hard meteor aficionados. The meteoroid stream that feeds the Taurids
    is very spread out and dissipated. That means the Taurids are extremely long lasting (September 25 to November 25) but usually don’t
    offer more than about 7 meteors per hour. That’ll be true even on the South Taurids’ expected peak night of November 4
    (before dawn November 5). The waxing crescent moon sets at early evening, leaving a dark sky for the South Taurid meteors, which
    are expected to produce the most meteors in the wee hours just after midnight on November 5.

    November 11/12, 2012, late night November 11 until dawn November 12 North Taurids
    This shower is long-lasting (October 12 – December 2) but modest, and the peak number is forecast at about 7 meteors per hour.
    Typically, you see the maximum numbers at around midnight to 1 a.m., when Taurus the Bull moves nearly overhead. This year, the
    thin waning crescent moon won’t rise till close to dawn, leaving a long dark night for these rather slow-moving but sometimes bright
    North Taurid meteors. you might even see some Taurid fireballs. The greatest numbers of North Taurid meteors come just after
    midnight on November 12..

    November 16/17, 2012, late night November 16 until dawn November 17 Leonids
    Radiating from the constellation Leo the Lion, the Leonid meteor shower is famous. Historically, this shower has produced some of
    the greatest meteor storms in history – at least one in living memory, 1966 – with rates as high as many thousands of meteors per
    hour. Indeed, on that beautiful night in 1966, the meteors did fall like rain. Some who watched the shower said they felt as if
    they needed to grip the ground, so strong was the impression of Earth plowing along through space, fording the meteoroid stream.
    The meteors, after all, were all streaming from a single point in the sky – the radiant point – in this case in the constellation Leo
    the Lion. Leonid meteor storms sometimes recur in cycles of 33 to 34 years, but the Leonids around the turn of the century – while
    wonderful for many observers – did not match the shower of 1966. And, in most years, the Lion whimpers rather than roars, producing
    a maximum of perhaps 10-15 meteors per hour. Like most meteor showers, the Leonids ordinarily pick up steam after midnight and
    display the greatest meteor numbers just before dawn. In 2012, however, the waxing crescent moon will setting at early evening,
    leaving a dark night for Leonid meteor shower.

    December 13/14, 2012, late night December 13 until dawn December 14 Geminids
    The final major meteor shower of every year (unless one surprises us!) is always the December Geminid shower, often producing
    50 or more meteors per hour. It is a beloved shower, because, as a general rule, it’s either the August Perseids or the December
    Geminids that give us the most prolific display of the year. Best of all, the new moon guarantees a dark sky on the peak night of
    the Geminid shower (mid-evening December 13 until dawn December 14). But the nights on either side of the peak date should be
    good as well. Unlike many meteor showers, you can start watching the Geminids by 9 or 10 p.m. local time. The peak might be around
    2 a.m. local time on these nights, because that’s when the shower’s radiant point is highest in the sky as seen around the world.
    With no moon to ruin the show, 2012 presents a most favorable year for watching the grand finale of the meteor showers.
    Best viewing of the Geminids will probably be from about 1 a.m. to 3 a.m. on December 14.

    The radiant for this shower is in the constellation Lyra, which rises in the northeast at about 10 p.m. Look towards Dublin!

    Will be visable in Kilkenny if the skies are clear.
