Legend of the Constellation

The Serpents although two separate constellations are usually referred to as one. The constellation Ophiuchus is sandwiched in between them. They are probably serpents that Ophiuchus cured people with.

Meteor Showers

There are 12 Meteor Showers that occur during the year within this constellation based on information gathered from Adam Mickiewicz University (Poland). The ones listed as the ones I've been able to find a date range for. For others if you have the time, you can visit the AMU site, obtains the SL value then use IMO tables to calculate the date. A lot of the Meteor Showers are weak and you need to do a lot of stargazing to spot them.
