Meteor Activity Outlook for October 23-29, 2021

- 2 Comments - In:

Philippe Jacquot captured this interloping fireball while photographing the local residents enjoying the fresh morning air. This fireball occurred at 04:00 CEST (02:00 UT) on 15 August 2021, near the town of La Giettaz, France.

During this period, the moon reaches its last quarter phase on Thursday October 28th. At that time the moon lies 90 degrees west of the sun in the sky and rises near 23:00 (on 27 Oct.) local standard time. This weekend the waning gibbous moon will rise during the early evening hours and will spoil the sky the remainder of the night. Late in this period meteor observers can view activity during the evening hours prior to moon rise. The estimated total hourly meteor rates for evening observers this week is near 2 as seen from mid-northern latitudes (45N) and 1 as seen from tropical southern locations (25S). For morning observers, the estimated total hourly rates should be near 12 as seen from mid-northern latitudes (45N) and 7 as seen from tropical southern locations (25S). 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. Rates are reduced during this period due to moonlight. 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 23/24. These positions do not change greatly day to day so the listed coordinates may be used during this entire period. Most star atlases (available at science stores and planetariums) will provide maps with grid lines of the celestial coordinates so that you may find out exactly where these positions are located in the sky. I have also included charts of the sky that display the radiant positions for evening, midnight, and morning. The center of each chart is the sky directly overhead at the appropriate hour. These charts are oriented for facing south but can be used for any direction by rotating the charts to the desired direction. A planisphere or computer planetarium program is also useful in showing the sky at any time of night on any date of the year. Activity from each radiant is best seen when it is positioned highest in the sky, either due north or south along the meridian, depending on your latitude. It must be remembered that meteor activity is rarely seen at the radiant position. Rather they shoot outwards from the radiant, so it is best to center your field of view so that the radiant lies at the edge and not the center. Viewing there will allow you to easily trace the path of each meteor back to the radiant (if it is a shower member) or in another direction if it is sporadic. Meteor activity is not seen from radiants that are located far below the horizon. The positions below are listed in a west to east manner in order of right ascension (celestial longitude). The positions listed first are located further west therefore are accessible earlier in the night while those listed further down the list rise later in the night.

These sources of meteoric activity are expected to be active this week.

Details of each source will resume next week when viewing conditions are more favorable.

You can keep track of the activity of these meteor showers as well as those beyond the limits of visual observing by visiting the NASA Meteor Shower Portal available at: https://meteorshowers.seti.org/ You can move the sky globe to see different areas of the sky. Colored dots indicate shower meteors while white dots indicate sporadic (random) activity. The large orange disk indicates the position of the sun so little activity will be seen in that area of the sky.

    I saw a giant green meteor fall almost directly south of me (DeLand, FL). I had no clue what it was, as I have only witnessed white streaks falling at what seemed a far distance. This one just flashed through the sky and appeared huge and was surely the brightest color green of anything I’ve ever seen in the night sky!!!

    Ok, so I am an 8th grader from Iowa. I was out on a Church trip to some person’s farm for a Halloween. We were on a hayrack ride and all of a sudden, a huge fireball the size of my index finger streaked I think to the West. It was insanely close because I heard a hissing sound. We have witnessed from the entire Youth Group on that night.
