Leonid Meteor Shower Tonight

The annual Leonid meteor shower hits tonight, as the Earth moves through the orbital path of a comet. The show is exceptionally good every 33 years, and in 1966 it was so dramatic some people thought the world was coming to an end. No one knows how it will look this year, so keep your fingers crossed. You don't need a telescope, just warm clothes, patience, and clear skies. The Leonids' unpredictability make it worth going out as soon as it's dark, but the peak is supposed to be between 11 PM and 1 AM (EST?). If it's cloudy, check out NASA's weather-balloon webcam.

      The peak IS supposed to be between 9-10pm EST (2am UT), but the shower is unviewable at that time from the US. Because of the position of the radiant (near the constellation Leo), very few meteors can be seen prior to midnight (local time) and the viewing isn't at its best until after 2am, and improves until dawn. The best part of the world for viewing that is the Middle East, Eastern and Northern Europe, and Africa. However, in the past, predictions for this particular shower have been way off base (18 hours late in the case of the 66 shower, and 12 early in case of last year's). If it arrives 3-9 hours late, the eastern US will be one of the best spots. You'll want to start viewing as early as possible (just before midnight), since (if the predictions are right)the most meteors will be falling then. However, there's no telling if this will be an amazing year like the '66 shower (dozens of meteors per second at the peak), or if it will be just a nice shower (50-200 meteors per hour).

    First, on the astronomy side, this will be the last good Leonid meteor shower. Ever. The Earth will move out of the path of the cometary debris, from now on, which will result in steadily weaker showers, eventually fading out to nothing.

Even NASA, who have multicast facilities, won't interrupt some pre-recorded multicast which they've been repeating every 10 minutes since mid-day, for the meteor shower of the millenium. Last year, all of the sites broadcating webcams and RealAudio links were overloaded to the point of collapsing. BUT THEY WILL NOT LEARN!!! What is WRONG with these people?!?!?!

Regardless of what is being reported at other web sites and in the popular press, this event could NOT have ben associated with the Leonid meteor shower. At the time of this event, North America was completely in the shadow of the Leonid stream, with the radiant located slightly east of the anti-zenith, that is, underfoot.

  10. Peak rate 2am /UTC/ (~not~ EST) by Cally · · Score: 5
    Times for astronomical events are given in UTC which is the same as GMT. The expected peak Zenithal Hourly Rate (ZHR) of 15,000 has been predicted for 2am GMT.;

    Note that the ZHR is a /theoretical/ maximum that would be seen by an observer if the radiant (the line of comet's orbit, ie the place in the sky where the meteors appear to radiate away from) were directly overhead. Actual observed rates are always lower.

    Hints and tips for observing :

    • No smoking ! It ruins night vision.
    • Get as far away from light pollution as possible.
    • The radiant rises at about midnight local time in the northern hemisphere, in the east (of course ;) )
    • Use a deckchair or lawn chair to prevent a permanent crick in the neck.
    • wrap up WARMLY -- good skies == clear skies == very cold !
    • Hot drinks (counter-intuitively) do NOT warm you up if you're outdoors.
    • If your location is clouded in, set an alarm clock for 60-90 mins and check again. If they storm, and you miss them, you'll kick yourself !

    Finally, don't be too disappointed if you "only" get a ZHR of a few hundred. Last year's observations allowed significantly better understanding of the separate streams of debris coming off the parent comet. Predictions are for a relatively quiet year next year, but much higher ZHRs in 2001 and 2002.

    1999 Leonids: Rapid Information Dissemination
    =============================================

    Dear meteor observer,

    >From earlier communications, you have learned that the IMO is setting
    up a communication network to obtain reliable information as soon as
    possible after the event in the morning of November 18. We invite you
    to contribute to this effort.

    First of all, we want to point out you must DISTINGUISH between the
    USUAL OBSERVATIONAL REPORTS, such as collected by the IMO's Visual
    Commission, and which may be used for detailed, global analyses, and
    the "EXPRESS REPORT" described below which serves as sole purpose the
    compilation of a rough but reliable picture of the activity within
    hours after the event.

    The EXPRESS REPORT should have the following format:

    Meteo R. Observer
    Fireball City (45N 10E)

    Time Interval (UT) Lim. Magn. Nr. of Leonids Remarks (if any)
    ------------------------------------------------ -----------------------
    01:15-01:30 5.8 27 None
    01:30-01:45 5.9 56 None
    01:45-02:00 6.1 156 None
    .
    .
    .

    To the extent possible, bin your observations for this "express report"
    in time interval of 15 MINUTES.

    (Again, the full report of your observations will be different from
    this express report, as shorter intervals are required as well as
    magnitude distributions and some additional data - see the earlier
    posted article with visual observing hints - but the above data
    suffice for the purpose indicated.)

    If you wish to collaborate with the IMO in this respect, please send
    your express report for the night of November 17/18 ONLY (or, of course,
    for any unexpected activity you might happen to witness)
    *** IMMEDIATELY AFTER THE OBSERVATION *** to the following email
    addresses:

    wgn@imo.net
    gyssens@hcoss.uia.ac.be

    The latter is a back-up address in case Web-site access to www.imo.net
    would prove to slow down our computer too much. This back-up address
    will be active only on November 17 and 18!

    Thank you in advance for any collaboration we may receive!

    If you're worried about the conjunction of this with the turn of the millenium, you should relax on this as well. The christian counting of years was calculated by Dennis the Short, in the mid 500s at the direction of the Pope. He worked off of events of the time that modern bible scholars and historians now know were inaccurate. The best calculations show that the birth of Jesus was 4 years earlier than Dennis calculated.

It wasn't like normal Leonid debris where the Earth basically slams into a cloud of tiny pebbles (think of driving through a bunch of no-see-ums); this was something that was travelling roughly in Earth's orbit and slowly grazed along the upper reaches of the atmosphere. It was in the far North, which suggests a slower planetary rotation time, as well.

    Bolides like this don't always break up, either. There was one a year or two ago (in the Southwest?) that was seen by thousands of people during daylight, but the trace it left suggested that it passed through and then left our atmosphere again.
