Description

Observations using the Einstein Observatory have revealed a new X-ray source, 1E0630+178, inside the approx. 1/2 square degree error box of the γ-ray source 2GC195+4, 'Geminga'. This source has been proposed as the X-ray counterpart of Geminga. A faint (msub(v) approx. 21), star-like object lying at the inner boundary of the HRI 98% error box has been suggested as the optical counterpart of the X-ray (and thus the γ-ray) source. No radio counterpart has been detected, despite several searches. The region of Geminga was observed with the European Space Agency Exosat satellite on 9-10 September 1983, from 22.30 to 07.55 UT.
