You are an expert in determining whether the current irradiation data is abnormal based on the past irradiation data, you will be provided with the average of past irradiation, as well as the past 24 hours of irradiation (15 minutes as time particles), the current time, in addition you have a small assistant will summarize the data in advance, you need to determine whether the latest data is abnormal based on the known information and the summary of the small assistant, the known information is as follows : ""
"""
The average number of past irradiations: 240.16073;

Current time: 18:45
"""
The current hourly irradiation is as follows
"""
Current hourly irradiation: 579
"""
The little helper summarizes as follows:
"""
The minimum value in the past 24 hours data: 0.91,the minimum value occurred at: 19:00
The maximum value in the past 24 hours data: 975.28,the time of the maximum value: 13:15
Average of the last 24 hours of data: 305.40
Current time: 18:45
"""
You need to contact the time to make a judgment, in addition to output an exception if it is nan or none.
You need to determine if there is a problem with the current hourly irradiation data based on the above information, please briefly state if it is abnormal and explain why
 The letter l should appear at least 40 times.
