	C&MS: The Theta Virginids
		Although it had long been known that abundant activity was present from the Virginid area during March and April, Hoffmeister's study was the first to attempt to identify the individual streams.
		The first apparent observation of the Theta Virginids was made by Robert P. Greg and A. Herschel during the interval of 1850-1867, when it became apparent that a radiant was active during March 5-17, from RA=190 deg, DEC=+1 deg.
		The first orbit represents that of the stream detected during the 1961-1965 survey, which was referred to as the "Northern Virginids." The other orbits are from the 1968-1969 survey and possess nearly identical durations, though the dates of nodal passage and the radiant positions were different.

		The Virginids are a stream of very long duration being active from early February until late May. Virginid meteors will appear to emanate from a very large radiant 15° in RA by 10° in Dec and will travel at a fairly slow speed across the sky.
		The Virginid stream has several maxima where the ZHR may reach between 5 and 10 meteors per hour but I can find no listing for an actual date of maximum for any of the sub-maxima.
		Virginid meteors should be easy to identify with there slow speed and large radiant size.

	C&MS: The Pi Virginids
		The Author has noted that the overall confusion of activity in the entire Virginid region during March and April generally makes visual observations useless---especially in the 19th century, when Denning's stationary radiant theory was in full swing.
		Another accurate method of studying these streams, and, especially the Pi Virginids, is by the use of radar.
		When the radar began operating on March 14, the first members of the Pi Virginids were detected and observations of stream members continued until March 23.

		The name change was meant to make it easier for newbies to understand the radiant position since it may not make sense to all to have the Virginid radiant located in western Leo as is the case in late January.
		April is a bit confusing as the Virginids are active from a radiant above Spica and the Sagittarid activity begins in Libra.
		I see now that the ALPO dates need to be modified so that the Virginids continue until mid-April and the Librid (Sagittarid) radiant needs to start in mid- April and not on April 1.

		Eta Virginids is a weak shower visible form February 24 through March 27.
		Theta Virginids also weak is visible from March 10 through April 21 peaking on March 20.
		Pi Virginids is visible from February 13 through April 8, the strongest of the three at a rate of 3 - 5 meteors per hour.

	NAMN Guide: Appendix A - List of Meteor Showers
		The radiant is above the horizon for almost the entire night, and meteors from this shower are best seen during the early to middle part of the night.
		Virginids (VIR) Active: Jan 25-Apr 15 Max: several Radiant: 195 -04 Diameter: 15/10 Drift: +0.5 -0.3 Velocity: 30 km/s Population Index: 3.0 ZHR: 5 NOTES: As there are a large number of low activity radiants close together, it is very difficult to distinguish what branches of the Virginids are active at any one time.
		With this is mind, the IMO has for the time being incorporated all Virginids seen into one shower.

		This galaxy is also known for its strong radio source Virgo A. A nice pair for observing is the 9th magnitude elliptical galaxies M 84 and M 86.
		Eta Virginids are observed between 24 February and 27 March,.
		The strongest shower amongst these three is the Pi Virginids with an hourly rate of 3 to 5 meteors.

	C&MS: The Eta Virginids (Site not responding. Last check: 2007-10-11)
		The Eta Virginids appear to be a fairly diffuse branch of the Virginid complex of February to April.
		In 1980, the early Eta Virginids were seen during February 23-March 10, with a maximum ZHR of 2.27+/-0.34 coming on March 9 from RA=184 deg, DEC=+1 deg.
		The Author has conducted a mathematical determination of the radiant ephemeris of this stream and revealed a daily motion of +0.9 deg in RA and -0.4 deg in DEC. Confirmation of this was given when the 37 radio meteor orbits were grouped according to inclination and then subjected to a least-squares fit.

		A result of the low radiant elevation is that Virginid meteors can, on occasion, have long, slow trajectories up from the horizon towards the zenith.
		Observed Virginid rates are typically low, usually no better than 2-3 meteors/hr in late March and early April.
		As with the earlier Virginids, the meteors can sometimes be long, slow and reasonably bright as they climb from the low southern sky.

	Constellation Virgo
		Virgo is the 6th sign of the zodiac; the sun passes through this constellation from late september to the end of october.
		For detailed information about M 49, M 58, M 59, M 60, M 61, M 89 and M 90 (as well as of the other galaxies) please refer to the Messier database.
		Three meteor showers seem to origin from Virgo: the Eta Virginids, Theta Virginids and the Pi Virginids.

	January to March 2005 \| International Meteor Organization
		The diffuse ecliptical stream complex of the Virginids gets underway by late January, running through to mid April, probably producing several low and poorly observed maxima in March or early April.
		The interesting late January to early February spell (during which several new, swift-meteor minor showers radiating from the Coma- Leo-Virgo area have been suggested in recent years), is severely moonlit, especially for most of the, perhaps core, January 20-27 period.
		This type of large, loose radiant area is similar to the Virginids, and the δ-Cancrids are probably an early part of the Virginid activity.

		A minor stream part of the large Virginid complex, and one of the better recognizable substreams.
		Maximum is ill defined and occurs near April 29 (radiant RA 229d, dec. -7d); the stream is also well recognizable however during the Lyrid maximum, when the radiant is located at RA 225d, dec. -5d.
		Activity is low, the radiant altitudes remain low for the Northern hemisphere, but the streams are recognizable.
