Hola a todos,

Este año las fechas elegidas para el encuentro son el 11 y 12 de Agosto por la fase de la Luna. Es una pena que coincida con el máximo de las Perseidas, pero...

También es una pena que coincide con el máximo de periodo vacacional.

Por mi parte haré todo lo posible por ir.

Saludos.

Mmmm, jooooo.

¿No estaría mejor el finde anterior?

Es que ese finde ya sabeis que es las perseidas y para una vez
que hay luna nueva es mejor observarlas bien en un sitio oscuro que te cagas.

Luego en la Astromartos estamos más tiempo babeando encima de los tacas, que mirando al cielo.

A votar....

Cometas y yo no nos lo vamos a perder, aunque esta vez no podre asistir a algunas charlas ya que también van a venir los cometas Jr de casa. el 13 nos vamos hacia Lanzarote. Total que el 10 cogeremos un vuelo Barcelona-Granada, un coche de alquiler Granada-Martos, estaremos hasta el lunes que con el coche iremos a Madrid para coger el vuelo Madrid-Lanzarote. Esto si que es un buen montaje

[novato]

Cual es el programa completo? Seguramente voy a finales de Mayo a Montoro que creo no queda lejos , ya que mi parienta tiene familia alli, si la puedo convencer de aqui a Agosto igual nos animamos.
Hay algun tipo de alojamiento preparado.hotel,camping....
Un saludo.

Pues a mí en principio me da igual porque siendo fin de semana no tengo problema, pero vamos que igualmente pienso ir sea la fecha que sea . Saludos.

Os paso la indormación de las Perseidas de Este año.

Perseids (PER)

Active: July 17 —August 24
Maximum: August 13; 5h —7h30m UT (λ = 140°0 —140°1) - but see text
ZHR = 100
Radiant: α = 046°; δ = +58°
Radiant drift: see Table 6
v∞ = 59 km/s; r = 2.6
TFC: α = 019°; δ = +38° and
α = 348°; δ = +74° before 2h local time
α = 043°; δ = +38° and
α = 073°; δ = +66° after 2h local time (β > 20° N)
IFC: α = 300°; δ = +40°; α = 000°; δ = +20° or
α = 240°; δ = +70° (β > 20° N)

The Perseids were one of the most exciting and dynamic meteor showers during the 1990s, with outbursts at a new primary maximum producing EZHRs of 400+ in 1991 and 1992. Rates from this peak decreased to ~ 100 —120 by the late 1990s, and in 2000, it first failed to appear. This was not unexpected, as the outbursts and the primary maximum (which was not noticed before 1988), were associated with the perihelion passage of the Perseids' parent comet 109P/Swift-Tuttle in 1992. The comet's orbital period is about 130 years, so it is now receding back into the outer Solar System, and theory predicts that such outburst rates should dwindle as the comet to Earth distance increases. However, some predictions suggested 2004 —2006 might bring a return of enhanced rates ahead of the usual maximum, and in 2004 a short, strong peak happened close to that anticipated pre-peak time. After that, activity seemed to be roughly normal in 2005, and the moonlit 2006 return was still to come when this text was prepared, but nothing untoward was predicted for 2007 in any case. An average annual shift of +0°05 in the λ of the “old” primary peak had been deduced from 1991 —99 data, and allowing for this could give a possible recurrence time around 9h UT on August 13 (λ = 140°16), if so a little after the most probable maximum, that of the “traditional” peak always previously found, which is given above. Another feature, seen only in IMO data from 1997 —99, was a tertiary peak at λ = 140°4, the repeat time for which would be 15h UT on August 13. Observers should be aware that these predictions may not be an absolute guide to the best from the Perseids, and plan their efforts accordingly, so as not to miss out, just in case!

Whatever happens, and whenever the peak or peaks fall around August 13, new Moon on August 12 creates perfect observing circumstances this year. For mid-northern latitudes, the radiant is sensibly observable from 22h —23h local time onwards, gaining altitude throughout the night. The UT morning-hour maxima suggested here would be best-viewed from across North America and northern South America, while the possible ~ 15h UT peak would fall best for Far Eastern Asia.

Visual and still-imaging observers should need little encouragement to cover this stream, but telescopic and video watching near the main peak would be valuable in confirming or clarifying the possibly multiple nature of the Perseid radiant, something not detectable visually. Recent video results have shown a very simple, single radiant structure certainly. Radio data would naturally enable early confirmation, or detection, of perhaps otherwise unobserved maxima, assuming more than one takes place, if the timings or weather conditions prove unsuitable for land-based sites. The only negative aspect to the shower is the impossibility of covering it from the bulk of the southern hemisphere.


Yo desde luego que intentaré ir como sea, pero almenos espero que si es ese fin de semana; nos busqueis un sitio más oscuro, con menos polvo y seamos más nazis con los focos de luz. La sierra de Cazorla esta muy bien para eso . Además que como reserva de la Biosfera, según la Declaración de la Palma
http://www.iac.es/gabinete/noticias/DeclaracionStarlight-1.pdf

Es candidata a Reserva del Cielo y puede que la organización de la Reserva apoyase algo así.
