Dear Rosely Gregio,

Nice report you sent for us. Nice to meet you again. I was quite unsure if I
was going to meet you for these days, and, finally I got you and your nice
report! Nice news.

Congratulations! You do not have to complain about if it is too long. Long,
but precise. That's makes a good difference: scientists from amateurs. No
complains about. We're altogether.

Here in Recife, I still am without many luck. Except for the big brilliant
satellite mentioned along this list. North Star(?). Nothing else!!!  I hope
that October comes as fast as possible. That's the month where I can take
much of my observations. It is when I will seriously begin. Otherwise, the
place where I live is really nice to observe group of stars. They're modest,
but too conspicuous to track a meteor.

 Besides, I live in a building. You can imagine: a guy, with a tape
recorder, a paper, binocular, charts etc, etc and etc...They will think that
I am ....Anyway, I do not care (;< At least, I do have some "windows" in the
top roof of my building that afford me dark conditions to follow some 'shy'
stars. In there, probably, I will have my luck back again!!!!And before
October. Who knows (?)

My regards to the group of amateurs you mentioned in your report.You wrote
along your report about "some impacts in the moon..." The moon is really
nice to be seen exactly from my window. There I have found some brilliants
lightning which I didn't give to much attention. Now that you mentioned
about the fact, I will gladly wait for more details. I hope you can indicate
precisely what they mean to mean. That's very important for me. I'm looking
forward to read about them.

Finally, the least, but not the last... Excuse if it goes in English. In
Portuguese would be okay too. There many non English speakers around to
follow our conversation. Good job, Gal!!!!

Greetings,

Marco Valois
