October 28 Meteor Observations from Southern California

I was out for 4 hours this morning. The humidity was a little higher (44%) than during recent sessions therefore the sky was just a tad hazy. I decided to look a bit higher in the sky and more toward the east to get better skies. The move paid off as all 4 hours had an LM between +6.1 and +6.2. The exact timing I was out was 1:30-5:30 am PDT (8:30-12:30 UT). I started out looking about 20 degrees south of the Pleiades and just let the sky drift by. This would have been a great night to break out the telescope as the stars were barely twinkling. Despite the slightly hazy conditions Canopus outshone Rigel at an altitude of less than 5 degrees. The temperature was about 10 degrees cooler than my other Orionid sessions. It started at 62F (17C) and fell to 58F (14C) by the end. Now for the details: . I counted a total of 40 meteors during the watch, not that impressive   There were several large gaps in activity that didn’t help. The hourly counts were 10-7-13-10. A majority of the meteors were 3rd magnitude with nearly all of the remainder evenly split between 2nd and 4th magnitude. The number of 5th magnitude meteors equaled the number of +1 and brighter. The brightest meteor of the session was an orange dart that...

Meteor Activity Outlook for 28 October-3 November 2017

During this period the moon will wax from half illuminated to nearly full by the end. Conditions will be favorable this weekend and early next week for viewing meteors in the hours before dawn. Late in the period the moon will become a problem as it is nearing its full phase and will remain is the sky most of the night. The bright moonlight will obscure all but the brighter meteors.

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...
