Here are today’s solar images taken from Al Sadeem Observatory, June 9, 2021.

The sky was generally clear with moderate breeze which provided good transparency but average seeing at the time these images were taken. 

Solar activity was at low levels over the past 24 hours.  AR2829 (Cso/beta) exhibited some decay of its entire sunspot structure. On the other hand, AR2830 and AR2831 are now behind the western limb. Another active region was recently see emerging in the encircled position; undesignated at this point. The latest sunspot number (based on visual count and Wolf number calculation) is 26. Several B-class and C-class solar flares, including a Type II radio emission associated with a non-Earth directed plasma ejection, were recorded by space weather agencies, mostly from AR2831.

Enhanced plages associated with the upper-mentioned sunspot groups and others near the eastern limb, few elongated stable filaments near the visible active regions, and some small quiescent prominences at the limbs, were the other noteworthy solar features distinctively captured in H-alpha imagery.

Space weather agencies* forecast solar activity to remain at low levels with chances of solar flares of mostly B-class to C-class intensity in the next few days, mainly from AR2829, as the other sunspot regions rotate away from Earth-view. 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.
