GS Pav: UGSS+E In https://www.aavso.org/vsx/index.php?view=detail.top&oid=24921 Please be careful and check the data when correcting the well-established type. A. Bruch simply was not aware that AAVSO observations only referred to outbursts (non-detections were not reported). The reported magnitudes were naturally almost the same and he made a wrong classification of NL (strangely, he did not refer to the GCVS classification, which gave the correct outburst cycle length). Have a look: Recent ASAS-SN data: https://asas-sn.osu.edu/sky-patrol/coordinate/1f93d862-9924-41c5-bf85-0728d…
