Meteor Activity Outlook for 13-19 October 2018 — 6 Meteor Showers Peak in October
- Meteor Activity Outlook for 13-19 October 2018 — 6 Meteor Showers Peak in October

During this period the moon will reach its new phase on Tuesday October 16th. At this time the moon will be located 90 degrees east of the sun and will set near midnight local summer time (LST). This weekend the waxing crescent moon will set during the late evening hours leaving the remainder of the night nice and dark for meteor observing. The estimated total hourly meteor rates for evening observers this week is near 3 for those viewing from the northern hemisphere and 2 for those located south of the equator. For morning observers the estimated total hourly rates should be near 22 as seen from mid-northern latitudes and 16 from the southern tropics. Evening rates are slightly reduced during this period due to moonlight. 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.

THESE SOURCES OF METEORIC ACTIVITY ARE EXPECTED TO BE ACTIVE THIS WEEK.
The Northern Taurids (NTA) are active from a large radiant located at 01:56 (029) +16. This area of the sky is located in southwestern Aries, 3 degrees south of the 3rd magnitude double star known as Mesarthim (gamma 2 Arietis). This position is close to the Southern Taurids so care must be taken in separating these meteors. You should have the two radiants near the center of your field of view to properly differentiate these sources. The maximum is not expected until early November so current rates would be 1 per hour or less. These meteors may be seen all night long but the radiant is best placed near 0200 LST when it lies on the meridian and is located highest in the sky. With an entry velocity of 28 km/sec., the average Northern Taurid meteor would be of slow velocity.

The Southern Taurids (STA) are active from a large radiant centered near 02:12 (033) +09. This position lies in northeastern Cetus, near the spot occupied by the 4th magnitude star known as xi 2 Ceti. These meteors may be seen all night long but the radiant is best placed near 0200 LST when it lies on the meridian and is located highest in the sky. Rates at this time should be near 3 per hour regardless of your location. With an entry velocity of 27 km/sec., the average Southern Taurid meteor would be of slow velocity.

The omicron Eridanids (OER) were discovered by Japanese observers using video data from SonotoCo in 2007-2008. The activity period ranges from October 16 – November 24 with maximum activity occurring on November 4th. This is a weak shower that usually produces rates less than 1 per hour, even at maximum activity. The radiant is currently located at 02:20 (035) -06, which places it in eastern Cetus, 8 degrees southwest of the 4th magnitude star known as delta Ceti. This location is close to the source of the Southern Taurids so care must be taken to separate these meteors. Like the STA’s these meteors may be seen all night long but the radiant is best placed near 0200 LST when it lies on the meridian and is located highest in the sky. With an entry velocity of 29 km/sec., the average omicron Eridanid meteor would be of slow velocity.

The Orionids (ORI) are active from a radiant located at 05:51 (088) +16. This area of the sky is located on the Taurus/Orion border, 8 degrees north of the bright 1st magnitude orange star known as Betelgeuse (alpha Orionis). This area of the sky is best placed near 05:00 LST, when it lies highest above the horizon. Current rates should be near 3-5 per hour no matter your location. With an entry velocity of 67 km/sec., most activity from this radiant would be of swift speed.

Revelation 12 New King James Version (NKJV)
3 And another sign appeared in heaven: behold, a great, fiery red dragon having seven heads and ten horns, and seven diadems on his heads. 4 His tail drew a third of the stars of heaven and threw them to the earth.
Satan Thrown Out of Heaven
7 And war broke out in heaven: Michael and his angels fought with the dragon; and the dragon and his angels fought, 8 but they did not prevail, nor was a place found for them[a] in heaven any longer. 9 So the great dragon was cast out, that serpent of old, called the Devil and Satan, who deceives the whole world; he was cast to the earth, and his angels were cast out with him.
