Another weak SC24 sunspot appears in the southern hemisphere

Would spots this weak have been seen by 19th Century observers?

Solar Cycle 24 spot - the start of something?

At least, it could be SC24 but the last magnetogram is from nearly 3 days ago.

I think the true test is if this spot lasts more than 48 hours. The others haven’t lasted that long.
