Last night we said goodbye to the November Orionids (NOO) and the Kappa Draconids (KDR) and hello to the Monocerotids (MON). Interestingly the NOO and MON were both produced by Comet Mellish. The NOO about 4000-5000 years ago while the MON were released more recently. For a bit more about these 2 showers see my previous post from a few days ago.
After the Sporadics (which are meteors not affiliated with any known shower, or at least not affiliated anymore), the best producers are the Geminids and Sigma Hydrids. Both showers have been producing some nice fireballs. Salvador Aguirre’s all-sky cam has been picking up a number of these objects over Hermosillo, Sonora, Mexico. You can see video of some of his detections on his blog (in Spanish).
