    Notes: Abstract The Explosive Transient Camera (ETC) has been performing automatic observations of the night sky since 1990. Since the launch of the Compton Gamma-Ray Observatory, the times and localizations ofγ-ray bursts detected by the Burst and Transient Source Experiment (BATSE) have been compared with ETC observations to determine whether the ETC had observed a γ-ray burst in progress. To date, six temporal and spatial correlations have been found, but no new optical radiation has been detected. In this paper, we present current results of ETC/BATSE correlated observations and describe plans for future observations.

    Notes: Abstract The High Energy Transient Experiment (HETE) will be able to perform multiwavelength observations ofγ-ray and X-ray bursts. HETE will potentially be able to localizeγ-ray bursts to a precision of ∼20 arc-minutes if significant X-ray flux is detected from the burst; a precision of ∼20 arc-seconds is possible if there is also significant UV radiation from the burst. HETE will broadcast information about bursts detected within seconds of their detection. This VHF-band broadcast will be received at a number of secondary ground stations (SGS) dedicated to HETE, and forwarded to a central distribution site at MIT, from which it is sent to interested observers via Internet.

    Notes: Abstract The High Energy Transient Experiment (HETE), scheduled for launch this year, is a small satellite dedicated to multiwavelength observations of γ-ray and X-ray bursts. The HETE spacecraft will be equipped with gamma-ray detectors, X-ray detectors with a coded mask, and ultraviolet-sensitive CCD cameras. The UV cameras on HETE are wide-field imagers which will a) provide UV images of the regions in which γ-ray or X-ray bursts are detected, before, duringand after the burst, b) detect UV transients, whether associated with a high-energy transient or not, c) monitor the brightnesses of field stars for variability over a wide range of timescales, and d) serve as star trackers for HETE. In this poster, we describe the HETE UV instrumentation, control software, and data products.
