ARLA/CLUSTER: Boas perspectivas para actividades em Meteor Scatter nos proximos meses

[João Costa > CT1FBF]

Meteor shower activity

The South African Radio League (SARL) report there are 88 meteor showers
present throughout the year, of which about ten are major showers and the
rest minor showers.

They say: The stronger meteor showers can provide VHF contacts up to  2,500
km on 50 MHz or 70 MHz SSB or digital.
The Orionids meteor shower will peak on Thursday night 20 October until
early morning on Friday 21 October 2016 when about 20 meteor trails will be
visible per hour.

A meteor burst that provides about 30 seconds of communication on 50 MHz
will yield only 3 seconds on 144 MHz and about a second on 432 MHz, but
digital communication is still possible on these bands.

On rare occasions, a meteor burst could last up to three minutes on 50 MHz.
The Orionids meteor shower will be followed by peak periods of the Leonids
on 17 November, the Geminids on 14 December 2016 and the Quadrantids on 4
January 2017. The visual rate for the Leonids will be around 20 trails per
hour, whereas the Geminids will peak at 120 per hour followed by the
Quadrantids at 100 per hour.
