Recent IMO analyses, based on data collected between 1984 and<br>2001, indicate that ZHR is generally above 30 hr-1 between about may 3-10.<br><br>The peak rates appear to be variable on a roughly 12-years timescale,<br>due to influence of Jupiter. According to this model, the most recent<br>highest rates should have happended around 2008-2010. Peak ZHR around<br>65 hr-1 is predicted for 2012. Please note that n – Aquariids radiant is<br>above horizon (thus making the shower usable for MS) in Europe only<br>(approximatively) in very late night and morning hours. While southern<br>Europe stations will be able to “see” the radiant till early afternoon,<br>in northern Europe skies the radiant culminates at reletively low<br>elevation so an observer is able to see the radiant for much less time.<br><br>Some daytime showers (? – Cetids, peaking May 20th being the most<br>significant ) will be also active this month; in addition to increasing<br>Sporadic Meteors background, they will provide good conditions for MS<br>DXing.<br><br>Theoretical peaktimes for May meteorshowers can be found here:<br><a href="http://mmmonvhf.de/ms.php" target="_blank">http://mmmonvhf.de/ms.php</a><br><br>SOURCE: Massimo, IV3NDC, team MMMonVHF<br>--<br><br>April to June<br><br>Meteor activity picks up towards the April-May boundary, with new Moon<br>gracing both the late April shower maxima. Sadly, the η–Aquariids in<br>early May are very poorly placed [for visual activities], with full Moon<br>on May 6, just a day after their predicted peak on the 5th. Stronger<br>η–Aquariid activity can persist at near-maximum levels for several days,<br>although the shower can be observed usefully only from equatorial and<br>southern hemisphere sites for a few hours before dawn. Rates should be<br>in the declining phase of the shower's theoretical 12-year cycle in<br>2012, with ZHRs of perhaps 60–70. The minor η–Lyrids fare little better,<br>expected at maximum perhaps on May 8 or 10, with May's waning gibbous Moon.<br><br><a href="http://www.imo.net" target="_blank">http://www.imo.net</a><o:p></o:p></p></div></div></div><p class=MsoNormal><br><br clear=all><br>-- <br> <br><br> Antes de imprimir este e-mail pense bem se é mesmo necessário.
