Hi Paolo,

It certainly looks like a classic microlens. I plan to take a final spectrum once it is back to normal just for the record.
There is an interesting claim of a possible lensing planet

though I have not heard any confirmation of this.

A message from Prof Subo Dong asking for any spectra you have not yet submitted to him

Dear All,


We are wrapping up the analysis of the nearby microlensing events and prepare the first paper of the event (we are currently planning two). Please make sure to upload all the data you have taken to me as soon as possible.


If possible, please take one more epoch of images at the baseline if you have not done so yet.


Best,
Subo

Thanks Robin, I just send him my two spectra. I should observe again the star but I need very good sky conditions (and long exposure time) to capture some profile details given the actual magnitude.
