Meteor over Coltesti, Alba Romania – Dec. 2012 © Sergiu Bacioiu

During this period the moon reaches its first quarter phase on Thursday April 14th. On that date the moon will be located 90 degrees east of the sun and will set during the mid-morning hours. This weekend the waxing crescent moon will set during the late evening hours and will not pose any problems for viewing meteor activity as long as you keep the lunar glare out of your field of view. The estimated total hourly meteor rates for evening observers this week is near 3 for observers located in the northern hemisphere and 4 for observers located south of the equator. For morning observers the estimated total hourly rates should be near 8 as seen from mid-northern latitudes (45N) and 11 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. 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 brightest meteors will be visible from such locations.

Radiant Positions at 9pm LDT

Radiant Positions at 9pm Local Daylight Saving Time

Radiant Positions at 1am Local Daylight Saving Time

Radiant Positions at 1am Local Daylight Saving Time

Radiant Positions at 5am LDT

Radiant Positions at 5am Local Daylight Saving Time

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 April 9/10. 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. 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 a 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 sigma Leonids (SLE) were first documented by Cuno Hoffmeister back in the 1940’s. Recent analysis show these meteors are active from April 8-25 with maximum activity occurring on the 15th. The radiant is currently located at 13:12 (198) +03. This area of the sky is actually located in central Virgo, 3 degrees east of the 3rd magnitude star known as Auva (delta Virginis). I’m not certain why this source is called the Sigma Leonids as even Hoffmeister placed the radiant in central Virgo, far from the star known as sigma Leonis. Perhaps back then there was a source of activity thought to be in southeastern Leo active at the same time? This radiant is best placed near 0001 local Daylight Saving time when it lies highest above the horizon. Rates are currently less than 1 per hour and may approach 1 per hour at maximum. With an entry velocity of 19 km/sec., the average meteor from this source would be of slow velocity.

The center of the large Anthelion (ANT) radiant is currently located at 14:12 (213) -13. This position lies in southeastern Virgo, 3 degrees south of the faint star known as kappa Virginis. Due to the large size of this radiant, Anthelion activity may also appear from the nearby constellations of Libra, eastern Hydra, and Serpens Caput as well as Virgo. This radiant is best placed near 0200 local Daylight Saving time, when it lies on the meridian and is located highest in the sky. Rates at this time should be near 3 per hour no matter your location. With an entry velocity of 30 km/sec., the average Anthelion meteor would be of slow velocity.

The April rho Cygnids (AEC) were discovered by Dr. Peter Brown during his meteoroid stream survey using the Canadian Meteor Orbit Radar. These meteors are active from April 11-May 4 with maximum activity occurring on the 22nd. The radiant is currently located at 20:18 (304) +41. This area of the sky is located in central Cygnus, just 1 degree northwest of the 2nd magnitude star known as Sadr (gamma Cygni). This radiant is best placed during the last hour before dawn when it lies highest above the horizon in a dark sky. Current rates are expected to be less than 1 per hour. With an entry velocity of 42 km/sec., the average meteor from this source would be of medium velocity. Note that these meteors are synonymous with the Nu Cygnids (Molau and Rendtel, 2009).

The delta Aquiliids (DAL) were discovered by Dr. Peter Jenniskens and mentioned in his book “Meteor Showers and their Parent Comets”. Recent analysis show these meteors are active from April 7-13 with maximum activity occurring on the 9th. At maximum the radiant is located at 20:32 (308) +12. This area of the sky is actually located in central Delphinus just north of the 4th magnitude star known as Deneb Dulfim (epsilon Delphini). This radiant is best placed during the last hour before dawn when it lies highest above the horizon in a dark sky. Rates at maximum are expected to remain less than 1 per hour. With an entry velocity of 63 km/sec., the average meteor from this source would be of fast velocity.

As seen from the mid-northern hemisphere (45N) one would expect to see approximately 5 sporadic meteors per hour during the last hour before dawn as seen from rural observing sites. Evening rates would be near 2 per hour. As seen from the tropical southern latitudes (25S), morning rates would be near 8 per hour as seen from rural observing sites and 3 per hour during the evening hours. Locations between these two extremes would see activity between the listed figures. The list below offers the information from above in tabular form. Rates and positions are exact for Saturday night/Sunday morning except where noted in the shower descriptions.

SHOWER DATE OF MAXIMUM ACTIVITY CELESTIAL POSITION ENTRY VELOCITY CULMINATION HOURLY RATE CLASS
RA (RA in Deg.) DEC Km/Sec Local Daylight Saving Time North-South
sigma Leonids (SLE) Apr 05 13:12 (198) +03 19 01:00 <1 – <1 IV
Anthelions (ANT) 14:12 (213) -13 30 02:00 3 – 3 II
April rho Cygnids (AEC) Apr 22 20:18 (304) +41 42 08:00 <1 – <1 IV
delta Aquiliids (DAL) Apr 09 20:32 (308) +12 63 08:00 <1 – <1 IV

      I didn’t really know what it was. I was driving home at 10;00 at night from a baseball game and I saw a huge blueish ball with a long white tail that got skinny at the end, like a tadpole soar above me. It was heading West. I think it was a meteor but I still don’t know for sure. I looked up pictures and it looks like it was a meteor. Could it have been one?

    My daughter was yelling what was that, I think I saw a shooting star. I could tell it was really something big the way she was yelling, but I had told her it was probably a firework or possibly a shooting star. This must have been what she saw.

    I could see a green meteor light up the sky south of detroit,
    it was north west bound,
    it went dark for a second then turned to a fireball that fizzled out before it got to close to the earth,
    from my vantage point it seemed to hit ground around Grosse ille, downriver Wynodotte area

    Luminescent green well defined spheroid object. Estimated velocity 7000 kmh. Vertical altitude, an estimated 1300 m. Traveling from an east to northwest direction. Viewed at an angle of inclination of 30 degrees; of a size comparable to that of a penny held at arm’s length. Uniform in color; no discernible trail, whatsoever. Elmhurst IL in the vicinity of York and Grand. Not a “fireball.”

    We got to witness the coolest thing lastnight at approximately 10:16pm. We were driving on Hwy 19 just east of Mexico Missouri when this ball of light came falling from the sky. At first we thought it was a firework, then we decided it was a shooting star or meteor. Either way, it was huge and bright! Of course my son and I made a wish on it, thinking it was a shooting star, but it was different. It had a light streak tail on it that started as white at the very end, turning yellow more towards the ball of fire, then it looked like red and either a blue or green fire ball. I have never seen anything like this, but definitely something worth being excited over for us!

    Was walking my dog, in my Mequon, WI neighborhood around 10:15 pm on Fri April 15 2016.
    We were walking towards the south, a bright emerald green fireball went shooting through the sky from east to west
    After just a few seconds it was out of my range of vision. There was no sound associated with the sighting.
    I wished it had just remained suspended in the sky allowing me to observe it for more than just a brief few seconds.
    It was spectacular!!

    I saw what looked like the end of it because it came from the east, looked blue at first but turned green as it went northwest. As we watched it go by, it appeared to go down in the field across the highway from us because it didn’t just disappear. It’s like it landed or went out. We are in Meadowbrook (Bethalto), IL. It was pretty darn awesome. We did think it was a shooting star.

    I saw a green flash as I was on the entrance ramp to I-55 at Joliet Road, southbound, in Indian Head Park. This flash was not high in the sky at all. It was very low – maybe a few stories high – traveling over the cars westbound. I thought it was some sort of fireworks, but it was only one streak that was rounded and very bright green at the large end in front with a light-colored streak for the rest of it. It didn’t last long – maybe 5 seconds and then it just wasn’t there. There were no noises or sparks.
