After about 18 hrs (4600 images) of monitoring V833 Tau with no flares I swapped to HIP25953 M4Ve last night with out much expectation as there forecast was for cloud.

However, to my surprise it flared. I still have to process the spectra but here is the discovery plot of the intensity of the zero order with timeĀ  v two comparison stars .

Each exposure is 100s through a SA200 grating. I will post the spectra once they are reduced.

Regards Andrew
