LUNAR TRANSIENT PHENOMENA

Mrs Winifred Cameron, now retired from NASA Goddard Space Flight Center, was the world expert in LTP. According her experience and scientific analysis the Moon is not completely dead and continue to show us some surface activities. 

These exceptional events are gaz ejection from the surface able to lighten some specific lunar formations. LTP happen sometimes just on the terminator, after the sun rise on the lunar relief and are in interaction with the solar activity. Others events occur when the Moon dives in the magnetic tail of the Earth, etc. 

All these sources of LTP are well-known and continue to be monitored mainly by amateurs from ALPO Lunar section. The Moon is far to be dead and that please me as this is one more reason to observe her face with accuracy in all possible lights including monochromatics, using both visual and spectroscopic methods.

RADIOASTRONOMY

The main activities accessible to amateur radio astronomers are the followings:

- Indirect method studies of solar phenomena, meteor infall, and Jupiter noise storms. This type work is usually done at the low radio frequencies, with relatively narrow band receivers. It does not involve sharp imaging of the radio noise source. This work is conducted mainly with communications-type receivers, requiring only a minimal need for auxiliary equipment. The expansion equipment usually takes the form of a strip chart recorder or an A/D (Analog to Digital) computer as a readout instrument, and a suitable DC (Direct Current) amplifier required to drive the readout (in some cases). This work, of course, does require a quiet radio band in the spectrum of interest.

- Imaging radio astronomy. This work makes up the bulk of amateur radio astronomy efforts. It is, by its very nature, best practiced in the VHF, UHF, and EHF radio spectra with receiving equipment of relatively broadband design. The reason for the broadband receivers is that all discrete radio objects radiate over a very broad spectrum, and the bandwidth of the receiver equates to the energy received from the object.

SETI@HOME

A short community of 200 professional astronomers are involved in long-term programs searching evidences of extraterrestrial intelligence in the universe, known under the acronym of SETI as it was quickly confirmed a direct contact was impossible to establish or very uncertain (CETI).

What arguments justify this fundamental research ?

- Bioastronomers believe the life has appeared in the cosmos wherein the optimist remind us there must be an infinity of life forms,

- What happened in the Earth coffin may happen elsewhere, even if life has evolved to species much different from what we know,

- At last we have to assume that human intelligence is not the top of the evolution.

Conclusion say bioastronomers, they must be more advanced civilizations than ours in the universe able to transmit voluntary of not electromagnetic waves we could detect.

Starting with these assumptions scientists conducted over fifty SETI projects. With high and low according political hazards, since 1960 they never had cancellation of these researches.

The last project to date is Optical SETI, the search for extremely short pulses in visible light (narrowband or monochomatic) from Sun-like stars. Amateurs can join OSETI. What you need is a 200mm scope or larger and a photometer.

Far to be a joke, some media however confused SETI and UFO at a point the US Congress cancelled his support to NASA project MegaSETI.

Since that sad day of 1993, private donations continue to support this activity bringing in 2000 the Planetary Society funding over $1,000,000. 

Today YOU are also in position to help SETI. 

If you own a computer you can even process yourself raw data from SETI@home project (now supported by BOINC) and send back your results to Berkeley University and SETI community. Over 5 millions amateurs are today involved in this quest, whom 600,000 are participating actively.
