PREVIEW of 144 MHz-Activities for the upcomming METEOR-Showers

UPCOMING METEOR SHOWERS: FEBRUARY - MARCH 2015

Only minor showers hit the Earth in February - March. The most significant is Capricornids / Sagittariids (Peaking February 1st, 22h UT), a medium-ZHR daytime shower; its radiant culminates at relatively low elevation in northern emisphere skies. Note that recent radio results indicate that Capricornids / Sagittariids maximum may fall variably sometime between February 1-4.

Southern Enisphere observers will check activity of α-Centaurids. The average peak ZHR of this shower, between 1988-2007 was only 6 hr-1; but in 1974 and 1980 outbursts of few hours’ duration yelded ZHR close to 20-30 hr-1. If the shower is of a long orbital period type as some analysts supect, there is the possibility there could be a fresh outburst this year, on February 8 at about 11h28m UT, an hour or so before the nodal crossing time (12h30m UT).

Even γ-Normids deserve a careful check in the southern Emisphere: observing rsults since 1999 have suggested the possibility of a short lived peak alternatively between λsol = 347°-357°, equivalent to 2015 March 8-18. However, a recent video analisys has indicated that the activity ocurs preferentially around March 25 (λsol=4°) instead.

Sporadic meteors are now reaching their seasonal minimum, but MS contacts via “sporadics”are still possible, especially in early morning hours.




For Radio Observers, the (Theoretical) UT peaks for upcoming showers in February-March 2015 are as follows:

Capricornids / Sagittariids (Daytime shower)
Active: January 13 – February 04
Maximum: February 01, 22h UT (λsol= 312.5°)
ZHR: Medium

α – Centaurids (Southern Emisphere shower)
Active: January 28 – February 21
Maximum: February 08 (λsol= 319.2°)
ZHR: Typically low (6 hr-1) but may reach 25 hr-1

χ- Capricornids (Daytime shower)
Active: January 29 – February 28
Maximum: February 13, 23h UT (λsol= 324.7°)
ZHR: Low

γ – Normids (Southern Emisphere shower)
Active: February 25 – March 28
Maximum: March 15 (λsol= 354°)
ZHR: Low (6 hr-1)

IMO fireball report goes live

On behalf of the International meteor Organization we forward the following message:

Dear all,

After huge efforts on the part of Mike Hankey and Vincent Perlerin, the IMO website now hosts a multi-lingual fireball report form at http://fireballs.imo.net/ Assuming no specialist astronomical knowledge or observing experience, this form easily guides the user through the process of reporting a fireball sighting in detail. The information gathered from the submitted reports is collected into a public database which can be searched for particular events: http://fireballs.imo.net/members/imo_view/browse_events

A team of volunteers has been hard at work translating the fireball form into more than 25 languages, and the IMO now requests your help in publicising it to local astronomical societies and groups in your region. We all know that large fireball events often excite local media. If such an event happens in your region, you can help by publicising the form widely to ensure reports are collected from as many eye-witnesses as possible.

If you would like to contribute a new translation in a language not already covered, or spot a mistake in the text of the form in your native language, please follow the instructions to translators at http://fireballs.imo.net/members/imo/translators

The IMO fireball report can be customized and branded for amateur societies, observatories, institutions or other astronomy organizations who receive fireball reports and enquiries from the public (see the Turkish Uzaybimer version at http://fireballs.imo.net/?org=uzaybimer for example). For more details, and to set up an account for your organization, please contact vperlerin@gmail.com

If you would like to test the form without submitting a false event to the database, please use the test version: http://dev.imo.amsmeteors.org/

Clear skies,
Megan Argo
IMO Press Officer
