The temporal variations of solar rotation in the photosphere, chromosphere, and corona
have been widely investigated, whereas the rotation of the solar transition region is rarely …

The temporal variation of solar coronal rotation appears to be very complex and its
relevance to the 11-year solar activity cycle is still unclear. Using the modified coronal index …

The solar chromosphere was daily observed in the Ca ii K line at the Mount Wilson
Observatory from 1915 August to 1985 July. A digitized data base was created, which …

Synoptic maps of Ca II K-normalized intensity at±40° latitude belt from Carrington rotations
827 (1915 August 10) to 1764 (1985 July 7) are utilized to investigate the long-term variation …

In this article, we present the differential rotational profile of extreme ultraviolet (EUV)
corona. For this purpose, we used observations with high resolution obtained from SDO/AIA …

The aim of this paper is to study the latitudinal variation in the solar rotation in soft X-ray
corona. The time series bins are formed on different latitude regions of the solar full disc …

To date, the rotational characteristics of the solar transition region remain unclear. In this
work, by applying the flux modulation method to the images derived from the Solar …

We report on the variability of the rotation periods of solar coronal layers with respect to
temperature (or height). For this purpose, we have used observations from the Atmospheric …

In this paper, by applying the wavelet transformation analysis to the data of the daily 10.7 cm
radio flux covering the period from 1947 February 14 to 2014 August 31, a significant period …

Coronal heating is a big question for modern astronomy. Daily measurement of 985 solar
spectral irradiances (SSIs) at the spectral intervals 1–39 and 116–2416 nm during 2003 …
