И я согласенO:) Смотрел вчера о Кита, незначительно ярче а Рыб. То есть в районе 3.5м. Хоть и максимум, по расчётам:rolleyes:

вот-вот, там где два врача, там три диагноза ..
нашёл в другом источнике, что максимум у omicron Ceti будет 31 декабря 2008 года в 00:54 UTC ..

The Psi Aurigids (PSA) were discovered among the radiants found by the IMO network of video cameras. This weak shower is active from October 8-18, which maximum activity occurring on the 15th. On the 8th, the radiant is located at 06:52 (103) +41. This position lies in a remote area of eastern Auriga, halfway between Castor (Alpha Geminorum) and Menkalinan (Beta Aurigae). This area of the sky is best placed in the sky during the last hour before dawn, when it lies highest above the horizon in a dark sky. Current rates should be less than 1 per hour no matter your location. With an entry velocity of 68 km/sec., most activity from this radiant would be of swift speed.

The Tau Cancrids (TCA) are active from October 9-25, with maximum activity occurring near the 17th. This shower was discovered by Peter Jenniskens and verified by IMO video data. Activity will be extremely weak this week from a radiant located at 08:24 (126) +29. This position lies in northwestern Cancer, 7 degrees east of the 1st magnitude star known as Pollux (Beta Geminorum). This area of the sky is best placed in the sky during the last hour before dawn, when it lies highest above the horizon in a dark sky. Current rates should be less than 1 per hour no matter your location. With an entry velocity of 69 km/sec., most activity from this radiant would be of swift speed.
