Change of critical frequency and height of E sporadic formed certain patterns. Solar activity, geomagnetic activity, and meteor showers influence this change. In order to get the pattern of critical frequency and height of E sporadic formed by meteoroid cluster the effect from solar and geomagnetic activity should be eliminated. June Lyrids, Shower 217, and Perseids meteor shower has the pattern of y = ax3 + bx2 + cx + d, with y is the quantity of meteor and x local time, with 0,0001 < a < 0,01; 0,1 < b < 0,6; -0,3 < c < 3,4; 11 < d < 19, showed result the critical frequency trends at Biak (01 deg 11 min S, 135 deg 07 min E) as 1. y = -0,6763 x + 15,476 at 15 to 17 June 1993 in 18.00-24.00 2. y = -0,0961 x3 + 1,0023x2 - 2,9815x + 5,2362 at 4 to 6 August 1993 in 0 1.00-06.00 and y = -0,0638x3 + 4,1376x2 - 89,175x + 641,15 at 4 to 6 August 1993 in 18.00-24.00 3. y = -0,0517x + 3,1683 at 12 to 14 August 1993 in 01.00-06.00 and y = 0,0349x3 - 2,1x2 + 41,588x - 268,44 at 12 to 14 August 1993 in 18.00-24.00 with y is the frequency in MHz and x local time. The research also obtained the pattern height of E sporadic as follows: 1. y = -5,625x + 201,63 476 at 15 to 17 June 1993 in 18.00-24.00 2. y = 2,125x3 - 22,425x2 + 66757x + 62,705 at 4 to 6 August 1993 in 01.00-06.00 and y=0,4478x3 - 26,966x2 + 538,21x - 3458,4 at 4 to 6 August 1993 in 18.00-24.00 3. y = 3,058x + 113,08 at 12 to 14 August 1993 in 0 1.00-06.00 and y =0,3072x3 - 18,411x2 + 364,54x - 2280,1 at 12 to 14 August 1993 in 18.00-24.00 with y is the height in kilometers (km) and x local time.
