Comet Observers' Forum na adresi
http://correio.cc.fc.ul.pt/~apereira/index.html
je veoma interesantan sajt za sve ljubitelje kometnih posmatranja. Izvestaji se publikuju i redovnije nego na encke sajtu. Ova stranica posebno dobro posluzi kada se encke sajt ne azurira i po par nedelja. Moj izvestaj sam poslao tamo vec kada sam se sasvim pomirio sa tim da ne mogu da nadjem adresu na koju se to cini. Napokon je izvestaj bio poslat i ubrzo mi je stigao veoma topao odgovor!

Neki mesec kasnije, krajem Avgusta 2001 A. Pereira je u jednoj rutinskoj kontroli neba svojim 14x100 binokularom otkrio Novu zvezdu u Sagitariusu. Ovo je objavljeno u obavestenju americkog udruzenja posmatraca promenljivih zvezda (AAVSO) kao i cirkularu br 7692 internacionalne astronomske unije (IAU)

Koristim ovu priliku da mu najtoplije cestitam ovaj sjajan i redak uspeh!!!
