The vintage Astroland Amusement Park on Coney Island is open -- for what may be its last season.

It opened Sunday under gloomy, cloudy skies.

The amusement park was purchased last fall by Thor Equities in a more than $1 billion plan to make it into a year-round destination. The group plans to close the 3.1-acre attraction at the end of the 2007 season.

Thor's plans include a mix of amusements and attractions, including a new roller coaster and a new hotel to accommodate the anticipated arrival of new tourists.

The famed Cyclone rollercoaster was not part of the purchase. The family that sold off the Astroland Park will continue to run it.
