Mr. Teles, from Serra dos Candeeiros (Portugal) send me this photograph taken last monday (2009 - 2rd March). Near 23:00 PM, at zenital position, this glowing object stays in that position for several minutes. I looked for some nightsky charts from that day and didn't find anything. The Big Dipper (Ursa Major) is under the object. Could be comet Lulin in those coordinates?
