The radio flux density is one of the most important parameters for predicting solar activity, such as solar flares and Coronal Mass Ejections. Compared to other burst types, solar burst type III (SRBT III) occurs most frequently due to solar flare phenomena. In the meter and decimetre wavelength range, gyro synchrotrons dominate, as do localized disturbances in the plasma frequencies caused by SRBT III. In this paper, we examine the most recent solar event that took place on 26th October 2021 in this gradual phase of the 25th solar cycle and can be detected from our site. In order to compare our results to other regions of the electromagnetic spectrum, we also used the data from the Solar Monitor and Space Weather Live website, where the data from NOAA and SDO/AIA were made publicly available. A wavelength of 10.7 cm corresponds to 101 solar flux units. Approximately 4.7 nT of interplanetary magnetic field exists and 1.7 nT in the northward direction. In the past 6 hours and 24 hours, flares of class C2 and M1 have been detected due to active region AR2887 generated by a 'beta-gamma' magnetic field.

“…Compared to other bursts, solar burst type III is the most common, mostly caused by solar flares. Solar radio burst type III is fascinating because it explains how particles ejected during massive solar activity are emitted [2]. There are three types of solar bursts: single bursts, group bursts, and complex bursts.…”

“…Although there are well-known five categories of SRBs [10], [11], [12] depending on the frequencies since the 1960s there are still some types related to solar magnetic reconnection that are not detectable or recognizable due to the variability of the Sun [13]. However, in this paper, we will examine a subtype III burst (SRB type VI) in more depth, which has never been done before.…”

We focus on the subcategory Solar Radio Burst Type III (Type VI) events detected on 11th July 2023, exhibiting an extended duration lasting almost 24 hours. Utilizing archival data from the e-CALLISTO network, we analyze the dynamical properties with emphasis on the 11:17-11:30 UTC interval due to their prominent features. The six selected stations recorded a series of well-defined SRB type III features with various intensities. Drift rates were calculated and produced the average absolute value of 1.4 MHz/s for a series burst and 8.2 MHz/s for a single burst, aligning with previous SRB type III drift rate ranges. Solar parameters on that day indicate a quite high range solar wind of 329.9 km/s, high solar coronal density of 6.07 protons/cm3, also high solar flux units in the radio sun measurement correlating with the abundance of sunspots numbers and an elevated peak in solar flare intensity on that month. Direct associations between SRB type VI and solar flares of class C4.5 were observed, while no direct links to Coronal Mass Ejections (CMEs) were identified within that timeframe. This research underscores the importance of understanding SRB type VI characteristics and their associations with solar activities for space weather forecasting.
