Adding ALT Tag Within This Javascript ?

I wish to add an ALT command to the following Javascript.

I have tried it with a ' /' /" or just " but always get an error message. I wish to add the ALT command to the URL link as is months [9].

How do I do it?

Also, I don't suppose there's any way of adding a mouseover command to the link while it is within this Javascript is there?

Code:
<SCRIPT LANGUAGE="JavaScript">

<!-- Begin
var months=new Array(13);
months[1]="this New Year!";
months[2]="this February!";
months[3]="this March";
months[4]="this Spring";
months[5]="this Spring";
months[6]="this June";
months[7]="this summer";
months[8]="this August <a href=http://www.augustwebsite.com August</a>";
months[9]="this <a href=http://www.septemberwebsite.com September</a>";

var time=new Date();
var lmonth=months[time.getMonth() + 1];
document.write(lmonth);

// End -->
</SCRIPT>
