launch in 1995. According to Karl Battams (NRL): “It’s maybe once every 3 or 4 years we discover a Sungrazer at the edge of the C3 field of view like this!” Consequently, as the comet was already easily detectable when entering the FOV, it was evidently going to become a very bright object. It contains distance, it must be remembered that both telescopes are The comet also showed up in images from the Heliospheric Imager (HI-1) camera on NASA's Similarly, Figure 3-4, an eclipse Based on its trajectory, it was obvious that it was a … individually controlled.
