Sunspots 25 Nov 2020 by flickr user Antonio Agnesi. All rights reserved. Used by permission. The image was captured through a Tele Vue Ranger refractor with Celestron Ultima 2x Barlow and Lunt Herschel wedge with Baader Solar Continuum filter. The camera used was a ZWO ASI 120MM. All gear was carried on a Skywatcher AZ-EQ6 mount. Exposures 5ms and the best 120 frames were stacked. macOS software used was ASICap, Lynkeos, and Photoshop CC.
According to a recent Solar Activity Update by the National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center, “Solar activity picked up at the end of November into early December, 2020, as several sunspot groups emerged or rotated onto the visible disk”. The update continues: “Solar activity is anticipated to slowly increase over the upcoming years towards the predicted solar maximum peak around July, 2025.” This is great news for observers of our nearest star! At times this year, there had been month-long sunspot “droughts” with no or few sunspots on the solar disk.
The return of Sun as a target of interest has led to a sudden uptick in Solar image postings to social media these past few weeks.
