Here are today’s solar images taken from Al Sadeem Observatory, June 27, 2021.
The sky was mostly clear with light breeze which provided good to average transparency and seeing at the time these images were taken.
AR2835 (Dso/beta) exhibited further growth of its entire sunspot structure throughout the monitoring period, though it has been quiet with only minor B-class solar enhancements recorded. A new smaller bipolar sunspot group was seen emerging just below AR2835 and has been recently designated as AR2836 (Bxo/beta). The latest sunspot number (based on visual count and Wolf number calculation) is 32.
Other noteworthy solar features observed were remnant enhanced plages within former sunspot groups AR2831 and AR2832, also the ones associated with AR2835 and AR2836, and few stable elongated filaments across the Sun’s disk, as distinctively captured in H-alpha imagery.
Space weather agencies* forecast solar activity to be at low levels with chances of solar flares of mostly B-class to possibly isolated C-class intensity, mainly from the upper mentioned sunspot groups in the next few days. Close monitoring is being conducted by numerous space weather agencies for any significant development.
Equipment used are Skywatcher 120mm refractor telescope with Baader filter and unmodified Canon EOS 1D Mark IV DSLR camera for visible imagery. For H-alpha imagery, the equipment used are Lunt 60mm H-alpha solar telescope, and QHYCCD 290III mono camera; all mounted on Skywatcher EQ6 pro mount Pre-processing of visible solar images was performed in PIPP, stacking in Autostakkert, slight wavelet adjustments in Registax 6, and post-processing in Adobe Photoshop CC.
