EX Hydrae

This interesting dwarf nova is an ideal object for almost everyone using a 6" or larger telescope. The field is easily located without setting circles, between the small but prominent constellations Crux and Corvus.

At minimum, EX varies continually round about Magnitude 13 but at outburst, it reaches magnitude 10. The outbursts are rare and only last about two days so it is easiy for the astronomical community to miss an outburst, unless the star is monitored continuously by amateurs.

You do not have to be able to see it, just report it as fainter than 12.0 or 12.7 or whatever but when you DO see a bright outburst, you should report it immediately to Jan Hers, myself, the VS Network or the AAVSO.

Enjoy EX Hya!
