Alpha Scorpiids Meteor Shower

The Alpha Scorpiids meteor shower takes place within the boundaries constellation of the Scorpius. The meteor showers occurs between 21 Apr- 26 May with the peak occuring on the 15-May every year The Solar Longitude, mistakenly known as Lambda Omicron is 55.2 degrees. This value sometimes expressed as S.L. or λ ☉ is the the date of maximum activity. It is measured as a degree with zero degree indicating spring equinox (roughly March 21st/22nd). 90 is the Summer Solstice, 180 is the Autumn Equinox and 270 is the Winter Solstice. This degree is independent of the calender. AMS .

Alpha Scorpiids can sometimes be misspelt as Alpha-Scorpids with just one i in the second name. It is definately two i`s because if you look up Antares, it is noted as being Alpha Scorpii from what the meteor shower gets its name from.

It is a faint and small meteor shower and if you plan to spend much time watching for them, you`ll probably be disappointed as they only appear three every hour. If you do decide to look out for them, good luck.

The source of the meteor shower is an asteroid whose journey take in towards the Sun then out towards Jupiter before coming back in again before actually reaching the gas giant. The picture below was generated using N.A.S.A. page and shows the path.

The source of the meteor shower is 2004 BZ74?. The closest star to the radiant point of the meteor shower is Antares. The coordinates can also be determined by the Right Ascension (240.7) and the Declination (-22.1).

The Zenith Hourly Rate or how many you expect to see during the hour is 3. The ZHR can radically increase if the comet or associated object is close by. The speed/velocity of the Meteor Shower particles is 35 km/s.
