That is already an older target (submitted here mainly for testing purposes). But it is still bright and certainly an easy and nice object to observe…

Yes last measurements show we are just passing the maximum around the 1st of august. around magnitude 12. Measurements in July are valuable to improve the rising light curve. And it is interesting to follow all along August to get the encreasing magnitude and color index. However this is a difficult SN to measure due to the location in NGC7331 close to the galaxy bulb. It gives a nice test to smart image processing.
