GSC 3656:1328

VAR CAS 06

Ett microlensing objekt i Cassiopeia SX och TT Cas ligger i närheten, objektet som förorsakar lensingen är

inte synligt ,ligger kanske för nära objektet om något år kanske man kan se den

Den hittills närmaste gravitations lins som observerats, möjligen förorsakad av en planet med 0.1 Sol massa?

Spectra is now showing a A star with lack of emission lines and the light-curve showing no flickering.

A real odd object, maybe a micro lensing…?
