Jan 10/11/12 Meteors

The most active minor meteor shower during the nights of Jan 10/11 and 11/12 was the December Leo Minorids (DLM). The DLM is one of many showers that seem to be active this time of the year in Leo, Leo Minor and nearby constellations. There is even some debate as to whether the DLM is a real shower or just a part of a continuum of showers.

Jan 8/9/10 Meteors

Cirrus again knocked down the number of observable meteors on the night of Jan 8/9. The next night was very clear and even saw a few more Coma Berenicids (COM) than usual. The night of Jan 9/10 sees the start of monitoring of the weak Northern Delta Cancrids (NCC) shower.

Jan 6/7/8 Meteors

The night of Jan 6/7 was nice and clear producing 32 detections. Though the next night was plagued with cirrus it did see some nice activity from the December Leonis Minorids (DLM). Though only 14 meteors were seen, four of them were DLMs. Too bad the night wasn’t clearer to see if any more fainter DLMs would have been seen.

Meteor Activity Outlook for January 4-10, 2014

The Meteor Activity Outlook for the period 2014 January 4-10 has been posted by Bob Lunsford on the American Meteor Society website.

The Outlook has details on meteors from the Antihelion region and the following showers: Quadrantids, Alpha Hydrids, January Leonids, and December Leonis Minorids.

Jan 5/6 Meteors

Now that’s more like it. After two straight nights with cirrus, a clear night once again produced a larger number of detections. (And yes I know I shouldn’t complain about a few nights of cirrus when much of the US and Canada is undergoing a deep freeze).

The short window to see Quadrantids has already closed and this shower is done for the year. Still the other minor showers and Sporadics produced 30 detections.

Jan 3/4/5 Meteors

The last two nights have been hampered by high cirrus in southern Arizona. As a result, meteor rates were suppressed. It also doesn’t help that last week’s major shower, the Quadrantids, has come and gone and none of the established meteor showers are showing much activity. Hopefully more will be picked up tonight since there are no clouds in the forecast.

Jan 2/3 Meteors and the Quadrantids

The Quadrantid meteor shower was most definitely active this morning over southern Arizona. Though the actual peak of Quadrantid activity likely occurred some hours later, both the SALSA3 video system and my own visual observations detected many Quads.

Over the course of 1 hour of observation under a limiting magnitude of 6.0 sky, I detected 29 meteors of which 22 were Quadrantids. Unlike the Geminids of last month, the Quads were relatively faint with no negative magnitude meteors. The video camera doesn’t see as faint as the human eye but makes up for lack in sensitivity by running tirelessly all night long. As a result the camera picked up even more meteors (64 in total with 42 being Quadrantids). If the peak really occurred over Asia as predicted then Quad activity should be good but rapidly falling over Europe and more or less over for the wester hemisphere tonight.
