Meteor Activity Outlook for October 11-17, 2025

During this period, the moon reaches its last quarter phase on Monday October 13th. On that date the moon will be located 90 degrees west of the sun and will rise near 23:00 local daylight saving time (LDST) on the previous evening. The waning moon will be a factor for morning observations early in this period, but its interference will lessen with each passing night. The estimated total hourly rates for evening observers this weekend should be near 4 as seen from mid-northern latitudes (45N) and 3 as seen from tropical southern locations (25S). For morning observers, the estimated total hourly rates should be near 7 as seen from mid-northern latitudes (45N) and 4 as seen from tropical southern locations (25S). Morning rates are reduced due to moonlight. The actual rates seen 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 11/12. These positions do not change greatly day to day so the listed positions may be used during this entire period. Most star atlases (available online and at bookstores 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 (culmination), either due north or south along the meridian, depending on your latitude. Radiants that rise after midnight will not reach their highest point in the sky until daylight. For these radiants, it is best to view them during the last few hours before dawn. It must be remembered that meteor activity is rarely seen at its radiant position. Rather they shoot outwards from the radiant, so it is best to center your field of view so that the radiant lies toward 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

The large radiant of the Southern Taurids (STA) is currently located at 02:44 (041) +13. This area of the sky is located in southern Aries, 3 degrees north of the 4th magnitude star known as mu Ceti. This area of the sky is best placed for observing near 02:00 LDST, when it lies highest in the southern sky.  Current rates are expected to be 2 per hour, no matter your location. With an entry velocity of 34 km/sec., the average STA meteor would be of medium velocity. These meteors are also known as the October Arietids while the radiant lies within the boundaries of Aries in October.

The Orionids (ORI) are active from October 2 through November 12, with maximum activity occurring on October 23rd. The radiant is currently located at 05:56 (089) +15, which places it in northeastern Orion, 8 degrees north of the 1st magnitude star known as Betelgeuse (alpha Orionis). This area of the sky is best placed for observing during the last dark hour prior to dawn, when it lies highest in the southern sky.  Current rates are expected to be near 2 per hour, no matter your location. With an entry velocity of 68 km/sec., the average ORI meteor would be of swift velocity.

The epsilon Geminids (EGE) are active from October 1st through November 4^th with maximum activity occurring on October 16^th. The radiant is currently located at 06:24 (096) +29. This area of the sky lies in eastern Auriga, 1 degree east of the 4th magnitude star known as kappa Aurigae. To best see these meteors, face toward the south during the last few dark hours prior to dawn. Rates at this time should be near 1 per hour as seen from the northern hemisphere and less than 1 as seen from south of the equator. With an entry velocity of 69 km/sec., the average EGE meteor would be of swift velocity.

The October Ursa Majorids (OCU) are a recent discovery by Uehara and his colleagues in Japan (Uehara et al., 2006), These meteors are only active from October 14-16 with maximum activity occurring on October 15^th. The radiant is located at 09:43 (146) +64. This position lies in northwestern Ursa Major, 1 degree northeast of the faint star known as 23 Ursae Majoris. See the charts for a better idea of the location of this source. This area of the sky is best placed during the last hour before dawn, when it lies highest above the northeast horizon. Current rates would be most likely less than 1 per hour no matter your location. But near maximum, rates may reach 2 per hour during the late morning hours as seen from the northern hemisphere. Due to its extreme northern position, these meteors are not visible from the southern hemisphere. With an entry velocity of 56km/sec., most activity from this radiant would be of swift speed.

The Leonis Minorids (LMI) are active from October 16^th to November 6^th, with maximum activity occurring on October 22nd. The radiant is currently located at 09:52 (148) +40, which places it in northern Leo Minor, 5 degrees southwest of the pair of 3^rd magnitude stars known as mu and lambda Ursae Majoris. These meteors are best seen by facing toward the east during the last couple of hours prior to dawn. This shower is better for observers situated in the northern hemisphere where the radiant rises far higher into the northeastern sky before the start of morning twilight. Current rates should be less than 1 per hour no matter your location. At 62km/sec., the average Leonis Minorid is swift. From my personal experience this minor shower produces a high proportion of bright meteors with persistent trains.

The last of the Daytime Sextantids (DSX) are expect this weekend from a radiant located at 11:04 (166) -06. This position lies in southeastern Leo, 3 degrees southwest of the 4^th magnitude star known as phi Leonis. Rates at this time should be less than 1 per hour no matter your location. With an entry velocity of 31 km/sec., the average DSX meteor would be of medium-slow velocity. No matter your location, these meteors are difficult to observe as the radiant lies roughly 30 degrees from the sun. Therefore, these meteors may only be seen during the last hour prior to dawn, shooting upward from the eastern horizon.

Sporadic meteors are those meteors that cannot be associated with any known meteor shower. All meteor showers are evolving and disperse over time to the point where they are no longer recognizable. Away from the peaks of the major annual showers, these sporadic meteors make up the bulk of the activity seen each night. As seen from the mid-northern hemisphere (45N) one would expect to see during this period approximately 7 sporadic meteors per hour during the last hour before dawn as seen from rural observing sites. Evening rates would be near 3 per hour. As seen from the tropical southern latitudes (25S), morning rates would be near 4 per hour as seen from rural observing sites and 2 per hour during the evening hours. Locations between these two extremes would see activity between these listed figures. Morning rates are reduced due to moonlight.

The list below offers information in tabular form of the active showers that I feel are within reach of the visual observer to discern. Hourly rates are often less than one, so these sources are rarely listed as visual targets in most meteor shower lists. If you are like me and wish to associate as many meteors as possible with known sources, then you will appreciate these listings. Before claiming to have seen meteors from these class IV showers, you should attempt to determine if these meteors actually belong to them and are not chance alignments of sporadic meteors. You can note parameters such as duration, length, radiant distance and the elevation of each meteor to help compute the probability of shower association.  It should be remembered that slow meteors can be seen from fast showers, but fast meteors cannot be produced from slow showers. Slower showers are those with velocities less than 35/km per second. Slow meteors can appear from fast showers when they appear close to the radiant or low in the sky. The table located on page 22 of the IMO’s 2025 Meteor Shower Calendar is a big help in aiding in the identification of meteors. If you record the length and duration of each meteor, you can use this chart to check the probability of the meteor belonging to a shower of known velocity. If the angular velocity is similar to the figure in the table, then your meteor probably belongs to that shower. Recognizing meteors from obscure showers is certainly not for the beginning meteor observer as it takes many hours to get a feel of what you are seeing. It is our hope that you will advance beyond watching meteors as a fireworks display and will want to help us expand our knowledge of the heavenly bodies we encounter in the skies above by classifying each meteor you see. Rates and positions in the table are exact for Saturday night/Sunday morning.

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. 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.

Class Explanation: A scale to group meteor showers by their intensity:

• Class I: the strongest annual showers with Zenith Hourly Rates normally ten or better.
• Class II: reliable minor showers with ZHR’s normally two to ten.
• Class III: showers that do not provide annual activity. These showers are rarely active yet have the potential to produce a major display on occasion.
• Class IV: weak minor showers with ZHR’s rarely exceeding two. The study of these showers is best left to experienced observers who use plotting and angular velocity estimates to determine shower association. These weak showers are also good targets for video and photographic work. Observers with less experience are urged to limit their shower associations to showers with a rating of I to III.

Robert Lunsford

Bob has been interested in the stars as far back as he can recall His first experience with meteors was a biggie, the 1966 Leonid shower. In 1980, a major awaking occurred. He received a sample copy of Meteor News. He was amazed to learn there was a group actually devoted strictly to meteor observing! He joined the group also started to view some of the minor showers list among the pages of Meteor News. Lastly, he was contracted by Springer Publishing in 2007 to write a book on observing meteors. The book is now available and hopefully will be a useful guide to all interested in the enjoyable field of meteor observing.
