Narrative:

On may/xa/99 at about XA30, I departed nashua's runway 32 and headed straight out, with permission of ash tower. The plan was to climb to 2400 ft (under class C airspace) and eventually clear class C airspace (base of class C airspace is 2500 ft). Approximately 1 min after departure, a cessna appeared at my 9 O'clock position and passed under me reappearing at 1 O'clock position. I reacted and pulled up 500 ft, entering class C airspace without permission. My GPS showed me in class C airspace and I exited as soon as possible. No contact made with approach.
