In 2020, the Orionids will peak on the night between 20–21 Oct
October Meteor Shower
Orionids are active every year in October, usually peaking around October 20/21. At its peak, up to 20 meteors are visible every hour.
They are the second meteor shower of the month—the Draconids usually peak around October 7 or 8.
Dust From Halley's Comet
The Orionid meteor shower is the second meteor shower created by Comet Halley. The Eta Aquarids in May is the other meteor shower created by debris left by Comet Halley.
Halley takes around 76 years to make a complete revolution around the Sun. It will next be visible from Earth in 2061. Mail pilot 3 39 coupe.
Orionids are named after Orion, because the meteors seem to emerge or radiate from the same area in the sky as the constellation.
What Time is the Meteor Shower Tonight
The table is updated daily when the Orionids are active and shows the position of the radiant in the sky for the upcoming night. The Orionids will be active starting 2 Oct 2020. Use the date drop down above the Interactive Meteor Shower Sky Map to change dates.

How to See the Orionids
You don't need any special equipment or a lot of skills to view a meteor shower. Even though all you really need is a clear sky, lots of patience, and our handy Interactive Meteor Shower Sky Map with a visibility conditions meter to see a meteor shower, the following tips can help maximize your shooting star viewing experience.
- Find a secluded viewing spot, away from the city lights. Once at the venue, your eyes may take 15 to 20 minutes to get used to the dark.
- Dress for the weather, and make sure you are comfortable, especially if you plan to stay out long. Bring a blanket or a comfortable chair with you—meteor watching can be a waiting game.
- Once you have found your viewing spot, lie down on the ground and look up in the direction of the radiant. Use our Interactive Meteor Shower Sky Map or the table above to find the current direction of the radiant in the sky.
Peak Hour Volume, Design Flow Rate, PHF
Peak Hour 4 4 0 100
It is commonly known in your area that the heaviest traffic flow rates occur between 4:00 PM and 6:30 PM. Your assignment for the day is to find the peak hour volume, peak hour factor (PHF), and the actual or design flow rate for an existing one-lane approach. To do this, you obtain a click-counter and position yourself at the intersection. Snippet io. For each fifteen-minute interval, you record the numbers of right-turns, left-turns, straight-through trucks, and straight-through passenger cars. Your tabulated values are as shown below.

Time Interval | Left Turns | Right Turns | ST Trucks | ST Cars |
4:00-4:15 | 5 | 10 | 6 | 30 |

If a truck is equal to 1.5 passenger cars and a right-turn is as well, and if a left-turn is equal to 2.5 passenger cars, then calculate the peak hour volume, peak hour factor (PHF), and the actual (design) flow rate for this approach.
Peak Hour 4
[Solution Shown Below]
Solution
The first step in this solution is to find the total traffic volume for each 15 minute period in terms of passenger car units. This is done by multiplying the number of trucks by 1.5, the number of right turns by 1.5, and the number of left turns by 2.5. We then add these three numbers and the volume of straight-through cars together to get the total volume of traffic serviced in each interval. Once we have this, we can locate the hour with the highest volume and the 15 minute interval with the highest volume. The peak hour is shown in blue below with the peak 15 minute period shown in a darker shade of blue.

Red giant trapcode suite 13 0 0 download free. The peak hour volume is just the sum of the volumes of the four 15 minute intervals within the peak hour (464 pcu). The peak 15 minute volume is 135 pcu in this case. The peak hour factor (PHF) is found by dividing the peak hour volume by four times the peak 15 minute volume.
PHF = 464 /(4 * 135) = 0.86
The actual (design) flow rate can be calculated by dividing the peak hour volume by the PHF, 464/0.86 = 540 pcu/hr, or by multiplying the peak 15 minute volume by four, 4 * 135 = 540 pcu/hr.
