Abstract
During the summer of 1978 the F Corona was observed from the ground in the near infrared at 2. and 3. in an attempt to measure the localized thermal emission from dust predicted by Peterson (1963) and several other workers. We failed to detect this emission even though our experimental errors were well below previously quoted emission values. If thermal emission peaks around the sun exist, we believe they are either much weaker or have different shapes compared to previous ones found. This result, if confirmed, will require a revision of the dynamics and physics of circumsolar dust.
