Likely alpha Monocerotids (AMO#246) outburst

#1  Postby newolder » Nov 19, 2019 11:11 am

A meteor outburst, or possible storm, has been forecast for November 22. Early UK risers (or about 11:50pm EST on Nov. 21 for USAians) should trace meteor trail observations to a point in the Monoceros constellation above the eastern horizon but below Orion...

Likely alpha Monocerotids (AMO#246) outburst on the morning of November 22, 2019

There is a good chance to observe a short-lived outburst of the alpha Monocerotids in the morning of the night 2019 November 21–22. Observers are encouraged to watch for possible alpha Monocerotids in the last hours of the night, from 4h15m UT onwards. If an outburst takes place it is likely to be centered around 4h50m UT with a duration of 15 up to 40 minutes maximum.

It could produce a ZHR value of maybe only about a hundred to even storm level (with a ZHR of more than 1000). However, because the radiant is not very high and also because of the possible twilight, the actual counts will be of course well below this level. In Helsinki, the Sun rises a little less than two hours later, so the twilight somewhat disturbs. The Moon is also present at the sky, but already as a crescent, so this may not disturb significant more than the twilight.

No one knows exactly where alpha Monocerotid meteors come from. The parent comet has never been seen. Based on the dynamics of its debris, it probably circles the sun every 500 years or so. We know the comet exists only because of the narrow trail of dust it left behind long ago. Earth has run into the dust trail at least 4 times, causing bright outbursts of meteors in 1925, 1935, 1985 and 1995.
