Oct. 20/21 2017 Orionid observations from North Florida

Greetings again all,       Fellow ACACers Neal, Shadow and Shade Brown joined me at Matanzas Inlet (MI) this morning for three more hours of monitoring the 2017 Orionid (ORI) meteor shower.  We went from 3:15 to 6:15 a.m. all told, and I had results almost identical to the previous morning.  The first hour I had 24 ORIs.  I fell just short of the “magic” 30 per hour rate threshold on the ORIs during the second hour with 29.   Then, unexpectedly, the ORI rate dropped in half and I had only 16 during the third hour.  Most unusual!  Here is my data: Observed for radiants: ORI:  Orionids STA: South Taurids NTA: North Taurids EGE: epsilon Geminids LMI: Leonis Minorids SPO: sporadics Date: Oct., 20/21, 2017. Observer: Paul Jones, Location:  north bank of Matanzas Inlet, Florida, 15 miles south of St. Augustine, Florida, Lat: 29.75 N, Long:81.24W, LM: 6.2, sky conditions: 10% cirrus haze, Facing: South. 0315 – 0415 EDT (0715 – 0815 UT), Teff: 1 hour, clear, no breaks 24 ORI: 0(1), +1(1), +2(6), +3(7), +4(6), +5(3) 5 STA: +1(1), +2(1), +3(2), +4(1) 1 NTA: +4(1) 2 EGE: +2(1) +3(1) 8 SPO: +2(1), +3(3), +4(2), +5(2) 40 total meteors 5 of the 24 ORIs, 1 of the STAs and 1 SPO left visible trains, most common colors were gold and yellow and some bluish tints in the brighter ORIs. 0415 – 0515 EDT (0815 – 0915...

Meteor Activity Outlook for 21-27 October 2017

During this period the moon will reach its first quarter phase on Friday October 27th. At this time the moon will be located 90 degrees east of the sun and will set near midnight local summer time (LST) for observers viewing from mid-northern latitudes. This weekend the waxing crescent moon will set shortly after dusk and will not interfere with meteor observing the remainder of the night.

Oct. 19/20, 2017 Orionid observations from North Florida – Awesome!

Greetings again all,     I was quite surprised and pleased to find the skies beautifully clear this morning for a change and was able to take full advantage of them indeed at Matanzas Inlet.  Observing conditions were superb with no clouds and a nice sea breeze to blow the bugs away.    The three-hour marathon session was a total joy as the pre-maximum Orionids were coming hot, bright, and heavy throughout the session and a few of the other active radiants kicked in nicely as well. I was kept quite busy indeed.  Without further adieu, here is my full report: Observed for radiants: ORI:  Orionids STA: South Taurids NTA: North Taurids EGE: epsilon Geminids LMI: Leonis Minorids SPO: sporadics Date: Oct., 19/20, 2017. Observer: Paul Jones, Location:  north bank of Matanzas Inlet, Florida, 15 miles south of St. Augustine, Florida, Lat: 29.75 N, Long:81.24W, LM: 6.5, sky conditions: clear, Facing: SE. 0330 – 0430 EDT (0730 – 0830 UT), Teff: 1 hour, clear, no breaks 18 ORI: 0(3), +1(2), +2(2), +3(3), +4(3), +5(5) 4 STA: +1(1), +2(2), +3(1) 2 NTA: +1(2) 2 EGE: +3(2) 13 SPO: +2(2), +3(2), +4(6), +5(3) 39 total meteors 6 of the 18 ORIs, 2 of the NTAs and 2 SPOs  left visible trains, most common colors were gold and yellow in the brighter ORIs. 0430 – 0530 EDT (0830 – 930 UT), Teff: 1 hour, clear, no breaks 23 ORI:...

A look at 14-15-16 October showers through CAMS

Two clear nights, 14-15 and 15-16 October allowed to collect a large number of orbits by the CAMS BeNeLux network. A look at the radiant distribution reveals distinct activity from a number of major as well as minor meteor streams. Apart from the Orionids and Taurids, the October Ursae Majorids displayed a remarkable strong activity. Introduction The night of 14-15 October had delivered no more than a single orbit in 5 years of BeNeLux network activity 2012-2016, weather having been year after year unfavorable. After two weeks of mediocre weather the Benelux CAMS network enjoyed a couple of network wide...

Meteor Activity Outlook for 14-20 October 2017

During this period the moon will reach its new phase on Thursday October 19th. At this time the moon will be located near the sun and will be invisible at night. This weekend the waning crescent moon will rise during the early morning hours but will not interfere with viewing meteors as long as you keep the moon out of your field of view. The estimated total hourly meteor rates for evening observers this week is near 4 for those viewing from the northern hemisphere and 3 for those located south of the equator. For morning observers the estimated total hourly rates should be near 17 as seen from mid-northern latitudes and 16 from the southern tropics. The actual rates will also depend on factors such as personal light and motion perception, local weather conditions, alertness and experience in watching meteor activity. Note that the hourly rates listed below are estimates as viewed from dark sky sites away from urban light sources. Observers viewing from urban areas will see less activity as only the brighter meteors will be visible from such locations. The radiant (the area of the sky where meteors appear to shoot from) positions and rates listed below are exact for Saturday night/Sunday morning October 14/15. These positions do not change greatly day to day so the listed coordinates may be used during this entire period. Most...
