Meteor prospects Spring and Summer 2008 |
|
|
|
Following early January’s Quadrantids, the opening months
of the year are generally regarded as a rather thin time for meteor observing,
with only minor shower and low background sporadic activity in evidence. Even the
most dedicated observers find the minimal rates - sometimes only one or two
meteors per hour - in February and early March rather a trial on their
patience.

Meteor Observing Prospects for Autumn/Winter 2007-8 |
|
|
|
Autumn in the northern hemisphere is the prime observing season for
meteor enthusiasts. Following the Perseids in August, several further showers
come to prominence during October-December. ‘Peak season’ is rounded off by the
Quadrantids in early January, following which activity reaches something of a
trough.
Even at times when major
shower activity is not expected, the ever-present background sporadic meteor
population can provide sufficient rates - perhaps 10-12/hr in the early hours
on a September morning - to reward patient watchers.

Meteor Prospects for Spring-Summer 2007 |
|
|
|
The year opened with very unfavourable conditions (a Full Moon!) for the Quadrantids in early January. In the coming months, however, there are plenty of good observing opportunities - looking ahead to the autumn, especially, the Orionid, Leonids and Geminids will each be well-placed for dark sky conditions. In the more immediate future, the Lyrids offer a chance to clock up some observing time with reasonable activity following the quiet months of the year’s opening quarter. Come high summer, the August’s Perseids are superbly-placed in 2007 |

Summer 2006 Prospects |
|
|
|
Every three years or so – roughly one-sixth of a Saros cycle – lunar phasing is such that the maximum of the Perseids is adversely affected by strong moonlight. This is, sadly, the case in 2006: Full Moon falls on August 09d, meaning that the shower’s peak on Aug 12-13 will be swamped by glare, and only the brightest meteors will be seen. This won’t deter ‘casual’ watchers – many local astronomical societies are doubtless planning barbeques/etc for the Saturday night – but productive serious, systematic watches are out of the question. Circumstances will be a whole lot better in 2007, when maximum is favourably-timed for western European longitudes in a moonless sky! For the meantime, observers have to make the most of the reasonable opportunities presented by the less prolific Capricornid and Aquarid showers active during late July’s Dark of the Moon. Coverage of these is just as important to the Meteor Section’s long-term work, and the combined activity from these radiants, coupled with reasonable sporadic rates, can make for productive viewing in the post-midnight hours. |

Winter 2005-6 Prospects |
|
|
|
Unfavourable lunar phasing has affected many of the major annual showers through the autumn of 2005, the Orionids, Leonids and Geminids each being notable casualties. A couple of reasonably favourable opportunities remain before meteor activity hits its annual low point during late January into February. |
