[vsnet-chat 5364] Re: V4641 Sgr: July 8-9 data from Monard

["Toni Scarmato" <toniscarmato@hotmail.com>]

Dear all,

regarding my observations of SGR4641 starting at 2002 July 5, I am sure that
I saw the intense increase of magnitude of the "star".
Also, I have observed this behaviour again the nigth of July 5 and 6.

Yet, the flares that I Have reported are not simultaneous.

To value the magnitude of the flares I Have used the stars GSC 6848:3606
10.9 and GSC 6848:3245 11.9. Because the short time to make the estimation
of the magnitude it is possible that I Have overestimated the flares,
but this is that I saw.

Best Regards,

Toni Scarmato
