V1117 Her observations requested
Abstract:
The peculiar Young Stellar Object (YSO) V1117 Herculis has undergone rapid fades and recoveries. Observations, both visual and multiwavelength, are encouraged to understand the rapidly-changing evolution of the protoplanetary clumps in the circumstellar disc.
Justification:
The behavior of V1117 Her’s historical fading episodes may indicate rapidly-changing evolution of the protoplanetary clumps in the circumstellar disc. Observing the 'mini-fades' that occur before the main event may provide insights into the asymmetry in the circumstellar clumps.
