As seen from the Northern Hemisphere, March is the slowest month of the year for meteor activity. No major annual showers are active and only a few very weak minor showers produce activity this month. The sporadic rates are also near their annual minimum, so there is not much to look forward to this month except for the evening fireballs that seem to peak this time of year. This could be due to the fact the Antapex radiant lies highest above the horizon this time of year during the evening hours as seen from the Northern Hemisphere. From the Southern Hemisphere, activity from the Centaurid complex begins to wane with only the weak activity visible from Norma and perhaps others nearby areas. At least southern sporadic rates are still strong to make the late summer viewing a bit more pleasurable.

During this period, the moon will reach its full phase on Tuesday, March 3rd. At that time, the moon will lie opposite the sun and will lie above the horizon all night long. Moonlight will be a major nuisance all this week on both sides of Tuesday’s full moon.

The estimated total hourly rates for evening observers this weekend should be less than 1 as seen from mid-northern latitudes (45°N) and near 1 as seen from tropical southern locations (25°S). For morning observers, the estimated total hourly rates should be near 3 as seen from mid-northern latitudes (45°N) and 6 as seen from tropical southern locations (25°S). Rates are reduced due to moonlight.

The actual rates observed 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 based on observations 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 from which meteors appear to originate) positions and rates listed below are exact for Saturday night/Sunday morning, January 3/4. These positions do not change greatly from day to day, so the listed coordinates may be used throughout this entire period. Most star atlases (available online, in bookstores, and at planetariums) include maps with celestial coordinate grids that can help you locate these positions 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 represents the sky directly overhead at the corresponding hour. These charts are oriented for facing south but can be used for any direction by rotating them accordingly. A planisphere or planetarium app is also useful for 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; therefore, it is best to view them during the last few hours of the night.

It must be remembered that meteor activity is rarely seen directly at the radiant position. Rather, meteors shoot outward from the radiant, so it is best to center your field of view so that the radiant lies near the edge rather than the center. Viewing in this way allows you to trace the path of each meteor back to the radiant (if it belongs to a shower) or in another direction if it is sporadic. Meteor activity is not visible from radiants located far below the horizon.

The positions below are listed in west-to-east order by right ascension (celestial longitude). The positions listed first are located farther west and are therefore accessible earlier in the night, while those listed farther down the list rise later.

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

.

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

The list below provides information in tabular form on the active showers that 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 catalogs. If you, like me, wish to associate as many meteors as possible with known sources, you will appreciate these listings.

 

Rates and positions in the table are exact for Saturday night/Sunday morning February 28/March 1.

SHOWER DATE OF MAXIMUM ACTIVITY CELESTIAL POSITION ENTRY VELOCITY CULMINATION HOURLY RATE CLASS
RA (RA in Deg.) DEC Km/Sec Local Standard Time North-South
Anthelion (ANT) 11:32 (173) +02 30 01:00 1 – 1 II

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.
