Sorry for the long radio silence but I've finally popped in to update all the aurora sightings. Many thanks for keeping on posting them - the information is still very useful. The (somewhat large!) spreadsheet I have of all the OW aurora / sunspot sightings is turning out to be a very useful resource. I've been contacted several times by researchers asking if there is evidence of any geomagnetic activity on a certain date, for example, and there are enough data there to write several more papers! So your time and diligence are still very much appreciated - thanks! :)

A super solar storm rocked Earth in 1872. They’re more common than you think.
February 4 and 5.

Currently our only ship with logs for February 1872 is Shenandoah

And would you know the Shenendoah did report a "brilliant aurora" on Feb 4 1872!
