कोडईकनाल टॉवर टनल टेलीस्कोप से सौर रहस्यों की गहन जांच: A new study by Indian Institute of Astrophysics astronomers, using the Kodaikanal Tower Tunnel Telescope, probes magnetic fields across solar atmospheric layers. Simultaneous observations of a complex sunspot in Hydrogen-alpha and Calcium II-8662 Å lines reveal that Hα samples higher chromospheric layers, estimating weaker fields (~500 G) than the photosphere (~2000 G). This multi-line spectropolarimetry
