	Arietid meteor shower (Site not responding. Last check: 2007-10-22)
		The Arietid meteor shower is the strongest daylight shower of the year.
		No one is sure where Arietid meteoroids come from, although some astronomers suspect they are debris from the sungrazing asteroid 1566 Icarus.
		Pre-dawn Arietids tend to be "Earthgrazers"--meteors that skim horizontally through the upper atmosphere from radiants near the horizon.

	June's Invisible Meteors
		"The Arietid meteors are active from a radiant located in eastern Aries approximately 10 degrees west of the Pleiades," explains Robert Lunsford, Secretary General of the International Meteor Society.
		The Arietids radiant is 15 degrees above the horizon, while the zeta Perseids radiant is a scant 4 degrees high.
		The Arietid and zeta Perseid showers are considered to be among the best showers of the year for radio observers.

	C&MS: The Autumn Arietids (Site not responding. Last check: 2007-10-22)
		One of these radiants, the "Xi Arietids" was said to be active during September and October from an average radiant of RA=30.9 deg, DEC=+9.6 deg, while another radiant---the "Sigma Arietids"---was said to be active during October from RA=41.9 deg, DEC=+13.7 deg.
		The October Arietids are a neglected shower among visual observers and, if not for the photographic and radar programs of the last 30 years, virtually nothing would be known of this stream.
		Combined observations of the October Arietids revealed an average magnitude of 3.37, based on 43 magnitude estimates, and a maximum ZHR of 3.4.

	Arietid meteor shower (Site not responding. Last check: 2007-10-22)
		Arietid meteors stream out of the constellation Aries; their source is unknown, although some astronomers suspect they come from the sungrazing asteroid Icarus.
		The Arietid radiant rises in the east about 45 minutes before the sun.
		(This is true for observers in both of Earth's hemispheres, north and south.) Pre-dawn Arietids tend to be "Earthgrazers"--meteors that skim horizontally through the upper atmosphere from radiants near the horizon.

	Record meteorite hits Norway
		It is probable that this meteorite is a fragment of the asteroid 1566 Icarus.
		The annual Arietid meteor shower emerges from a point in the sky only 30 degrees from the sun.
		For the Arietids, he noted that the Apollo asteroid Icarus (1566) possessed an orbit with similar characteristics.

	Constellation Aries
		The May Arietids are a daylight meteor shower active between May 4th and June 6th.
		The Delta Arietids shower was discovered in 1959 by analyzing photographic meteor orbits.
		The duration of the Autumn Arietids meteor shower extends from September 7th to October 27th.

	C&MS: The Arietids (Site not responding. Last check: 2007-10-22)
		The question of the stream's inclination has remained ever since 1951, with radar studies in Australia, the United States, and the Soviet Union variously revealing values of 19 deg to 38 deg, however, in 1975 the results of an Australian radar survey conducted during 1969 were published, which perhaps shed new light on this problem.
		Although no formal explanation seems to have been offered as to why the radiant's daily motion has been so difficult to determine, it may be possible that the inclination variances noted previously are directly responsible---especially since the radiant's motion in declination seems the hardest to establish.
		Thus, since Gartrell and Elford's data seem to indicate several filaments working simultaneously to produce the Arietid activity, the same filaments might be contributing to the confusion of the determination of the shower's daily motion.

	Meteors and Meteor Showers
		Without the heat shields, the spacecraft would vaporize due to temperatures approaching several thousand degrees F. Meteors and meteor showers can occur in the daytime as well, they just can't be seen due to the Sun's glare.
		As an example, one of the strongest annual meteor showers is the Arietids which occurs on or near June 8th.
		Because of the effects of perspective, the meteors from meteor showers appear to radiate from one point in the sky.

	Sungrazing comet - Wikipedia, the free encyclopedia
		The Marsden and Kracht groups both appear to be related to Comet 96P/Machholz, which is also the parent of two meteor streams, the Quadrantids and the Arietids.
		Studies show that for comets with high orbital inclinations and perihelion distances of less than about 2 Astronomical Units, the cumulative effect of gravitational perturbations over many orbits is to reduce the perihelion distance to very small values.

		Researchers aren't certain where the Arietids come from, but they might be debris from sungrazing asteroid Icarus.

	June 2006 Meteor Showers
		The Arietids will peak on the morning of June 7th.
		What makes the Arietids so unusual is the fact that the shower's radiant is fairly close to the Sun and rises only 45 minutes or so before sunrise, making this a "daytime" shower.
		The Arietids peak also occurs within a few hours of these listening times, so 2006 is a good year to listen for these meteors.

		Truth be told, I don't follow astrology and couldn't tell you what sign my wife is. The Arietids shower peaks tomorrow but I decided to start a day early.
		I observed for about 45 minutes and was able to spot 5 meteors, and only one might have been an Arietids but was rather high in the sky.
		I had read earlier that the Arietids are good for FM Radio observations because the ZHR is equal to 60 but that peak occurs after sunrise.

		The direction was from east-north east to west and its magnitude around -8 at least (i am not familiar with so bright objects!) and rather fast.

	June Daytime Showers (Site not responding. Last check: 2007-10-22)
		In this report we will concentrate on the Arietids, the best daylight shower of the year, with occasional references to the zeta Perseids.
		Nonetheless, the derived peak rate for the Arietids compares with the best of the consistent night-time showers (Perseids, Geminids, Quadrantids), and it is a longer lasting shower than any of these.
		The best match among known objects for a parent body of the Arietids is the Apollo asteroid 1566 Icarus.

		The Arietid meteor shower, so called because they seem to stream out of the constellation Aries peaks, on June 8, although they last from late May to early July.
		While it is thought the Arietids come from the asteroid 1556 Icarus no one is sure.
		Since the pre-dawn Arietids tend to be “Earthgrazers” some skim horizontally through the atmosphere, slow and bright.

		From September 7th to October 27th the shower Autumn Arietids is active.

	April to June 2005 \| International Meteor Organization
		Later in May and throughout June, most of the meteor action switches to the day sky, with six shower maxima expected during this time.
		Although a few meteors from the ο-Cetids and Arietids have been reported from tropical and southern hemisphere sites visually in past years, ZHRs cannot be sensibly calculated from such observations.
		Signs of most of these peaks were found in radio data from 1994-2002, though some are difficult to define because of their proximity to other sources, while the Arietid and ζ-Perseid maxima tend to blend into one another, producing a strong radio signature for several days in early June.

	RE: (meteorobs) Re: Arietids
		I used several filters and the polarizing one gave me the better results, even if I did not caught one meteor, I have results at night...

		I hope some of you get a good laugh out of it too...

		There's more - the Marsden and Kracht I groups, together with 96P/Machholz 1 may also be related to several meteor showers: The closest link is between Marsden, Kracht I and the Daytime Arietids.
