Nova in constelatia ''Sagetatorul''-Nova in Sagittarius

Iata o stire venita din partea userului  ''gp100man'' din grupul yahoo  ''60mmtelescopeclub''.
Stirea anunta o nova de aproximativ 8mv in constelatia Sagetatorul.
Dau mai jos intreg mesajul lui gp100man,inclusiv micul comentariu gastronomic despre placintele cu dovleac recomandate de prietena si colega noastra de club ,Carol!

Duminica,8 Iulie a.c., gp100man a scris pe grupul yahoo ''60mmtelescopeclub'':


On July 07,2012, a few hours ago Japanese astronomers discovered a
bright new NOVA in Sagittarious between the "lid" and "spout" in the teapot/archer constellation. Right Ascension 18 H 20.5 M, Declination -27o 44" (equinox 2000).
The really really new NOVA is rated at 7.8 magnitude.
The Celestron website states that their Powerseeker 60EQ model 21043(my favorite 60mm due to the F/15 focal ratio and good quality lens)will go down to 11.4 limiting steller magnitude. 


WHO WILL BE THE FIRST ASTRONOMER IN THIS 60MM ONLINE TELESCOPE CLUB TO SPOT THE NEW NOVA. 


Speaking for myself, I don't think I've ever seen a NOVA, so this 
will be quite an adventure this coming next few days. And I hope the NOVA gets brighter, like 1572 type brighter.
This info is rather preliminary, so if you can get more info on the NOVA, please post it here.
Carol. I'm eating as much pumpkin pie as I can wishing for clear skies this coming week.

Aceeasi stire ,cu ceva mai multe date de la Roger Sinnott din partea revistei  ''Sky&Telescope'',prin alertele lor ''AstroAlert''.
Nova poarta denumirile de ''Nova Sagittarii 2012 No. 4'' si de asemenea '' PNV J18202726-2744263''.
Succes la observatii,Mircea

A fairly bright nova has been discovered in Japan by Koichi Nishiyama (from Kurame) and Fujio Kabashima (Miyaki). They made their find on July 7, 2012, using a 105-mm f/4 camera lens and CCD, describing the nova as magnitude 7.8. It is located in Sagittarius roughly between the "lid" and "spout" of the Teapot stars, at right ascension 18h 20.5m, declination -27° 44' (equinox 2000.0). A number of other observers in Japan have made confirming sightings.
The discovery was announced on CBET 3166, issued July 7th by the Central Bureau for Astronomical Telegrams in Cambridge, Massachusetts. This circular assigns the star the official designations Nova Sagittarii 2012 No. 4 and also PNV J18202726-2744263.

Am plotat harta de mai jos cu ajutorul plotterului AAVSO pentru un camp de 5x5 grade si stabilind o magnitudine  minima de 10mv pentru stelele de comparatie.

Binoclurile mele  Fujinon Mariner 7x50mm sau Baigish 10x50mm ar trebui sa fie suficiente pentru observarea novei in aceasta faza a evolutiei,mai bine zis  a eruptiei sale.


Multumesc lui gp100man,''60mmtelescopeclub'',Sky&Telescope si AAVSO pentru informatii.
