Essay On Anik E2
The authors has revisited the Anik E1 and Anik E2 failures with the details of the events and the scrutiny of space weather conditions at that time. This communication failure is often used as the example to illustrate the potential damages from the space environment on our satellites and communications systems. The events begins on 20 January 1994 when Anik E1 began spinning uncontrollably; this disabled 40 northern Canadian communities’ telephone service and the radio stations. Luckily, by activating the redundant momentum wheel system (which is used for altitude determination and control), Telesat Canada was able to restored Anik E1 service. However, at 0214UT, January 21, 1994, Anik-E2 faced the similar issue except this time the backup system also failed. Due to the Anik-E2 outrage, more than 1600 northern communities lost their data and almost all their television services. To reestablish control of Anik-E2, Telessat

How did this paper extend your knowledge of the space environment?
It gave me a really good idea on how the space environment can affect our communication system. We understand that space environment will cause damages to the satellites and this paper demonstrates the conditions that might lead to the similar kind of events and the magnitude of damages it can cause. It also showed how different data can used to describe the overall picture of the space environment; particularly, how they used the use of Pc5 data to provide evidence of the ULF mechanism in accelerating the electrons.
8. What do you wish the authors had done differently in explaining their science results?
The authors has explained the events and space environment very well. One thing that I wish to be included in the paper is a plot of the relative location of the spacecrafts like Anik E1, Anik E2,YKC and GOES during the events so that we can visualize the situations better and understand how well these values represent the actual environment Anik E1 and E2
