Lambda Bootids Meteor Shower

When and where does the Lambda Bootids Meteor Shower Occur

The Lambda Bootids  meteor shower takes place within the boundaries constellation of Bootes. The meteor shower occurs between Jan 17-18 with the peak occurring on the Jan 17 every year.

The Solar Longitude (Abbrev: S.L., λ ☉) is 296 degrees, this value 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 .

The closest star to the radiant point of the meteor shower is Xuange. The coordinates can also be determined by the Right Ascension (221.5) and the Declination (42.4).

The speed/velocity of the Meteor Shower particles is 41 km/s.

The Lambda Bootids appear a couple of weeks after the first meteor shower and the most prolific at that, the Quadrantids. The Lambda Bootids occur in the roughly in the same area as the Quadrantids but a bit to the east.

How to Find and View the Lambda Bootids

Northern Hemisphere

The Northern Hemisphere has the better chance of seeing the meteor shower. The star that the shower gets its name from is visible in the night sky after six p.m. Over the course of hours, the star will rise higher in to the sky allowing it to be seen clearly.

Southern Hemisphere

From the southern hemisphere (Sydney being Reference Point), the star Lambda Bootis which lends its name for the meteor shower is very hard to see. The star is visible in the early hours, roughly 4 o'clock, just before the Sun rises. It is best seen between north and north easterly direction. The star barely rises in the sky before the Sun brightens to block out any view.
